OM5-WMV/WV
Analog Voltage Input Modules, Wide Bandwidth
DESCRIPTION
FEATURES
Each OM5 wide bandwidth voltage input module provides a single channel
of analog input which is amplified, isolated, and converted to a high level
analog voltage output (Figure 1). This voltage output is logic-switch
controlled, allowing these modules to share a common analog bus without
the requirement of external multiplexers.
● ACCEPTS MILLIVOLT AND VOLTAGE LEVEL SIGNALS
● HIGH LEVEL VOLTAGE OUTPUTS
● 1500Vrms TRANSFORMER ISOLATION
●
ANSI/IEEE C37.90.1-1989 TRANSIENT PROTECTION
The OM5 modules are designed with a completely isolated computer side
circuit which can be floated to 50V from Power Common, pin 16. This
complete isolation means that no connection is required between I/O
Common and Power Common for proper operation of the output switch. If
desired, the output switch can be turned on continuously by simply
connecting pin 22, the Read-Enable pin to I/O Common, pin 19.
● INPUT PROTECTED TO 240VAC CONTINUOUS
● 100dB CMR
● 10kHz SIGNAL BANDWIDTH

1µV/°C DRIFT
The input signal is processed through a pre-amplifier on the field side of
the isolation barrier. This pre-amplifier has a gain-bandwidth product of
5MHz and is bandwidth limited to 10kHz. After amplification, the input
signal is chopped by a proprietary chopper circuit. Isolation is provided by
transformer coupling, again using a proprietary technique to suppress
transmission of common mode spikes or surges. The module is powered
from +5VDC, 5%.
● CSA CERTIFIED, FM APPROVED, CE COMPLIANT
● MIX AND MATCH OM5 TYPES ON BACKPANEL
A special input circuit provides protection against accidental connection of

ter. This allows a 2-wire loop powered transmitter to be directly connected
to the module without requiring an external power supply. The regulated
supply will provide a nominal +20VDC at a loop current of 4mA to 20mA.
● PROVIDES ISOLATION FOR NON-ISOLATED 2-WIRE
The OM5-TX will provide a 1500V isolation barrier for non-isolated 2-wire
field transmitters. It can also be used when additional isolation is required
between an isolated 2-wire transmitter and the input stage of the control
room computer.

OM5-IFI
Frequency Input Modules
FEATURES
DESCRIPTION
● ACCEPTS FREQUENCY INPUTS OF 0 to 100kHz
● PROVIDES HIGH LEVEL VOLTAGE OUTPUTS
● TTL LEVEL INPUTS
Each OM5-IFI Frequency input module provides a single channel of fre-
quency input which is isolated and converted to a high level analog voltage
output. This voltage output is logic switch controlled, which allows these
modules to share a common analog bus without the requirement of external
multiplexers (Figure 1).
● 1500 VOLT TRANSFORMER ISOLATION
● ANSI/IEEE C37.90.1-1989 TRANSIENT PROTECTION
● INPUT PROTECTED TO 240VAC CONTINUOUS
● 0.05% ACCURACY
The frequency input signal can be a TTL level signal or a zero-crossing signal.
Terminal 3 (+In) on the field-side terminal block is the “common” or ground
connection for input signals. A TTL signal is connected from terminal 2 (–In)
to terminal 3 (+In), while a zero-crossing signal is connected from terminal 4
(+EXC) to terminal 3 (+In). Input circuitry for each of the signal types has
hysteresis built in. An input signal must cross entirely through the hysteresis
region in order to trigger the threshold comparator.
● MIX AND MATCH OM5 TYPES ON BACKPANEL
● CSA CERTIFIED, FM APPROVED, CE COMPLIANT
A 5.1V excitation is available for use with magnetic pick-up or contact-
closure type sensors. The excitation is available on pin 1 (–EXC) and the
excitation common is pin 3 (+In).
The modules are designed with a completely isolated computer side circuit
which can be floated to 50V from Power Common, pin 16. This complete
isolation means that no connection is required between I/O Common and
Power Common for proper operation of the output switch. If desired, the
output switch can be turned on continuously by simply connecting pin 22,
the Read-Enable pin to I/O Common, pin 19.
A special circuit in the input stage of the module provides protection against
accidental connection of power-line voltages up to 240VAC.

OM5-LTC
Linearized Thermocouple Input Modules
FEATURES
● INTERFACES TO TYPES J, K, T, E, R, S, N, AND B
The OM5-LTC modules are designed with a completely isolated computer
side circuit which can be floated to 50V from Power Common, pin 16.
This complete isolation means that no connection is required between I/O
Common and Power Common for proper operation of the output switch. If
desired, the output switch can be turned on continuously by simply
connecting pin 22, the Read-Enable pin to I/O Common, pin 19.
THERMOCOUPLES
● LINEARIZES THERMOCOUPLE SIGNAL
● HIGH LEVEL VOLTAGE OUTPUTS
● 1500Vrms TRANSFORMER ISOLATION
The OM5-LTC can interface to eight industry standard thermocouple types:
J, K, T, E, R, S, N, and B. Its corresponding output signal operates over a
0V to +5V range. Each module is cold-junction compensated to correct for
parasitic thermocouples formed by the thermocouple wire and screw
terminals on the mounting backpanel. Upscale open thermocouple detect
is provided by an internal pull-up resistor. Downscale indication can be
implemented by installing an external 47MΩ resistor, 20% tolerance,
between screw terminals 1 and 3 on the OM5-BP backpanels.
●
ANSI/IEEE C37.90.1-1989 TRANSIENT PROTECTION
● INPUT PROTECTED TO 240VAC CONTINUOUS
● 160dB CMR
● 95dB NMR AT 60Hz, 90dB at 50Hz
●
1µV/°C DRIFT
Signal filtering is accomplished with a six-pole filter which provides 95dB
of normal-mode-rejection at 60Hz and 90dB at 50Hz. Two poles of this filter
are on the field side of the isolation barrier, and the other four are on the
computer side.
● CSA CERTIFIED, FM APPROVED, CE COMPLIANT
● MIX AND MATCH OM5 TYPES ON BACKPANEL
After the initial field-side filtering, the input signal is chopped by a
proprietary chopper circuit. Isolation is provided by transformer coupling,
again using a proprietary technique to suppress transmission of common
mode spikes or surges. The module is powered from +5VDC, 5%.
DESCRIPTION
Each OM5-LTC thermocouple input module provides a single channel of A special input circuit provides protection against accidental connection of

open or high, the hold mode is enabled. The module is designed with a
completely isolated computer side circuit which can be floated to 50V from
Power Common, pin 16. This complete isolation means that no connection
is required between I/O Common and Power Common for proper operation
of the track and hold circuit. For a low state, simply connect pin 23, the Write-
Enable pin, to I/O Common, pin 19.

GROUNDING
ELECTRICAL
Figure 4 details the optional ground jumper configuration available on the
OM5-BP-16-C backpanel. Jumpers J1, J3, and J4 are factory installed.
P1 AND P2 CONNECTOR
Connection to the host system is made at connectors P1 and P2. These
connectors are electrically equivalent. Two connectors are provided to allow
both analog input and analog output from host systems having individual
input and output connectors.
Jumper J1 connects the AGND shield wires (pins 3, 6, 9, 12, 15, 18, 21, and
24) to the backpanel signal ground. This provides a ground connection
between the host system and backpanel. Jumper J1 is required if output
modules are used, or if there is no high impedance sense input (input low of
a differential or pseudo-differential system) on the host measurement sys-
tem.
ADJACENT CHANNEL JUMPERS
Adjacent channels may be connected together to provide an isolated output
signal from an isolated input module, providing two levels of 1500V
isolation. This capability is provided with the 15 jumpers labeled JP1
through JP15 on headers E1, E2, and E3. A simplified drawing of the OM5-
BP-16-C schematic for Channel 1 through 4 is shown in Figure 3.
Jumper J3 connects the SENSE line (pin 25) to the backpanel signal ground.
If the host system has the capability, this allows measuring the OM5-BP-16-
C ground potential.
For proper operation of the output switch or track-and-hold circuit when
usingtheOM5backpanels, acurrentpathmustexistbetweenthehostcontrol
logic power common and module I/O Common (module pin 19). This path
can be established on the OM5-BP-16-C via jumper J4. If this connection
exists elsewhere in the system, jumper J4 should be removed since possible
ground loops could exist. Other connections of power ground and signal

analog buses; one for analog input and one for analog output. This two-
bus configuration takes advantage of the switch controlled outputs on the
input modules and the track-and-hold inputs on the output modules. A
temperature sensor is mounted on each channel to provide cold junction
compensation for thermocouple input modules (See Figure 6 for
schematic). Field connections are terminated with four screw terminals at
each module site. Up to four OM5-BP-16-MUX-C backpanels may be
daisy-chained. Use OMX-CAB-01-C cable for daisy chaining and OMX-
1315-XX-C cable for connecting to host computer.

GROUNDING
ELECTRICAL
Figure 7 below details the optional ground jumper configuration available on
the OM5-BP-16-MUX-C backpanel. Jumpers J1, J2, and J4 are factory
installed.
P1 CONNECTOR
The 26 pin P1 connector provides the signal interface between the OM5-BP-
16-MUX-C backpanel and the host measurement system. Two separate
analog bus connections are provided; one for analog input signals and one
for analog output signals. Two sets of six address lines and an enable pin
allow input and output modules to be independently multiplexed onto their
respective analog signal bus. R0 thru R5 and RDENAB are used for input
modules, and W0 thru W5 and WRENAB are used for output modules.
Jumper J1 connects the SIG COM shield wires (pins 2, 5, and 6) to the
backpanel signal ground. This provides a ground connection between the
host system and backpanel. Jumper J1 is required if output modules are
used, or if there is no high impedance sense input (input low of a differential
or pseudo-differential system) on the host measurement system.
Jumper J2 connects the SNS LO line (pin 4) to the backpanel signal ground.
If the host system has the capability, this allows measuring the OM5-BP-16-
MUX-C ground potential.
ADDRESS SELECTION
The OM5-BP-16-MUX-C backpanel has address decoding circuitry to allow
multiplexinganycombinationofupto16inputoroutputmodules. Capability
is also provided in the address decode circuitry to expand the system to 64
channels (four OM5-BP-16-MUX-C backpanels) of multiplexed input or
output. Jumpers on HD10 header, E1 and E2 group, select which set of 16
addresses are assigned to a particular backpanel. The E1 group assigns a set
of 16 addresses for input modules, and the E2 group assigns a set of 16
addresses for output modules. The table below shows the correlation of
jumper position to address range.
For proper operation of the output switch or track-and-hold circuit when
usingtheOM5-BP-16backpanels, acurrentpathmustexistbetweenthehost
controllogicpowercommonandmoduleI/OCommon(modulepin19). This
path can be established on the OM5-BP-16-MUX-C via jumper J4. If this
connection exists elsewhere in the system, jumper J4 should be removed
sincepossiblegroundloopscouldexist. Otherconnectionsofpowerground
and signal ground usually occur at the A/D or D/A converter of the host
measurement system.
E1 Jumper Pos
E2 Jumper Pos
Address Range/Mode
If the connection of power common and SIG COM shield wires exist in the
host measurement system, a resistive connection between SIG COM and the
backpanel signal ground can be made via R1. R1 can be aslargeas 10K ohms;
100 ohms is a recommended value. Jumper J3 can be used to connect the
SNS LO line to R1 when this ground configuration is used.

Forfullprotectionagainstlargeelectricaldisturbancesonthefield-sideofthe
OM5 modules, a #10-32 ground stud is provided on the backpanel. An
electricalconnectionbetweenthisgroundstudandsystemgroundshouldbe
provided with a large gauge wire of the shortest possible length. When this
connection is made, a possible ground loop could result through the SIG
COM shield wires and backpanel signal ground. If the application involves
only input modules and a differential input is used by the host measurement
system, J1 should be removed. Remember that J1 is required if output
modules are used or if the host system does not have differential inputs.
To connect multiple OM5-BP-16-MUX-C backpanels in this expanded
configuration, use interconnect cable OM5-CAB-01-C.
POWER
The OM5-BP-16-MUX-C backpanel requires external +5VDC 5% power.
The chassis mounted OMX-976 power supplies have adequate capacity to
power any combination of modules.
FUSING
The OM5-BP-16-MUX-C backpanel power is fuse protected through F1.
This is a Littlefuse type 252004, 4 amp fuse. Zener diode DZ1 provides extra
protection by clamping the input power voltage to +5.6V. If the input supply
voltage connection is reversed, this zener diode will be forward biased and
fuse F1 will be blown.

SELECTION GUIDE FOR OM5 ISOLATED
SIGNAL CONDITIONING PRODUCTS
General Description
ANALOG VOLTAGE INPUT MODULES, NARROW BANDWIDTH (4Hz BW)
OMEGA® OM5 Series Isolated Signal Conditioning Modules are low cost,
high performance, plug-in signal conditioners. Each OM5 module provides
a single channel of isolated analog input or output. Input modules interface
to all types of external sensors. The modules filter, isolate, amplify, and
convert the input signal to a high-level analog voltage output. The output
modules accept a high-level analog voltage signal from a host system, then
buffer, isolate, and amplify before providing a process current or voltage
output to field devices. Over 115 different OM5 modules are available
encompassingawideselectionofisolatedanaloginputandoutputfunctions.
Analog inputs include voltage and current in narrow and wide bandwidths,
Thermocouple, RTD, Potentiometer, Strain Gage, Frequency, and 2-Wire
Transmitter. Custom I/O ranges are also available. All modules are CSA
certified and FM approved for safe operation in Class I, Division 2, Groups
A, B, C, and D hazardous environments.

OM5-IMV/IV
Analog Voltage Input Modules, Narrow Bandwidth
FEATURES
● ACCEPTS MILLIVOLT AND VOLTAGE LEVEL SIGNALS
DESCRIPTION
Each OM5-IMV and OM5-IV voltage input module provides a single
channel of analog input which is filtered, isolated, amplified, and converted
to a high level analog voltage output (Figure 1). This voltage output is
logic-switch controlled, allowing these modules to share a common analog
bus without the requirement of external multiplexers.
● HIGH LEVEL VOLTAGE OUTPUTS
● 1500Vrms TRANSFORMER ISOLATION
●
ANSI/IEEE C37.90.1-1989 TRANSIENT PROTECTION
The OM5 modules are designed with a completely isolated computer side
circuit which can be floated to 50V from Power Common, pin 16. This
complete isolation means that no connection is required between I/O
Common and Power Common for proper operation of the output switch. If
desired, the output switch can be turned on continuously by simply
connecting pin 22, the Read-Enable pin to I/O Common, pin 19.
● INPUT PROTECTED TO 240VAC CONTINUOUS
● 160dB CMR
● 95dB NMR AT 60Hz, 90dB at 50Hz
●
●
●
0.05% ACCURACY
0.02% LINEARITY
1µV/°C DRIFT
Signal filtering is accomplished with a six-pole filter which provides 95dB
of normal-mode-rejection at 60Hz and 90dB at 50Hz. Two poles of this filter
are on the field side of the isolation barrier, and the other four are on the
computer side.
● CSA CERTIFIED, FM APPROVED, CE COMPLIANT
After the initial field-side filtering, the input signal is chopped by a
proprietary chopper circuit. Isolation is provided by transformer coupling,
again using a proprietary technique to suppress transmission of common
mode spikes or surges. The module is powered from +5VDC, 5%.
● MIX AND MATCH OM5 TYPES ON BACKPANELS
A special input circuit on the OM5-IMV and OM5-IV modules provides
protection against accidental connection of power-line voltages up to
240VAC.

RTD excitation is provided from the module by two matched current

to flow in each RTD lead, which cancels the effects of lead resistances. The
excitation currents are very small (0.25mA for 100Ω Pt and 120Ω Ni, and
1.0mA for 10Ω Cu) which minimizes self-heating of the RTD.

OM5-IP4/IC4/IN4
Linearized 4-Wire RTD Input Modules
Each OM5 4-wire RTD input module provides a single channel of RTD input
FEATURES
which is filtered, isolated, amplified, linearized, and converted to a high
level analog voltage output. This voltage output is logic switch controlled,
which allows these modules to share a common analog bus without the
requirement of external multiplexers.
●
INTERFACES TO 100Ω PLATINUM, 10Ω COPPER,
OR 120Ω NICKEL RTDs
● TRUE 4-WIRE INPUT
The OM5 modules are designed with a completely isolated computer side
circuit which can be floated to 50V from Power Common, pin 16. This
complete isolation means that no connection is required between I/O
Common and Power Common for proper operation of the output switch. If
desired, the output switch can be turned on continuously by simply
connecting pin 22, the Read-Enable pin to I/O Common, pin 19.
● LINEARIZES RTD SIGNAL
● HIGH LEVEL VOLTAGE OUTPUT
● 1500Vrms TRANSFORMER ISOLATION
●
ANSI/IEEE C37.90.1-1989 TRANSIENT PROTECTION
● INPUT PROTECTED TO 240VAC CONTINUOUS
● 160dB CMR
RTD excitation is provided from the module by a precision current source.
The excitation current is available on two leads which are separate from the
two input signal measuring leads. The excitation current does not flow in
the input signal leads, which allows RTD measurement to be totally
independent of lead resistance. The excitation current is very small (0.25mA
for 100 Ω Pt and 120 Ω Ni and 1.0 mA for 10Ω Cu) which minimizes self-
heating of the RTD.
● 95dB NMR AT 60HZ, 90dB AT 50HZ
● CSA CERTIFIED, FM APPROVED, CE COMPLIANT
● MIX AND MATCH OM5 TYPES ON BACKPANEL
Signal filtering is accomplished with a six-pole filter which provides 95dB
of normal-mode-rejection at 60Hz and 90dB at 50Hz. Two poles of this filter
are on the field side of the isolation barrier, and the other four are on the
computer side. After the initial field-side filtering, the input signal is
chopped by a proprietary chopper circuit. Isolation is provided by trans-
former coupling, again using a proprietary technique to suppress transmis-
sion of common mode spikes or surges. The module is powered from
+5VDC, 5%.
DESCRIPTION
In RTD temperature measurement applications requiring a very high level
of accuracy, the OM5 4-Wire RTD input module offers a significant
advantage over 3-wire measurement techniques (Figure 1). The OM5
measures only the voltage dropped across the RTD and almost completely
ignores the resistance or length of the RTD lead wires. The OM5
3-Wire RTD module provides lead resistance compensation, but requires
equal lead resistances, while the 4-wire modules do not require matched
lead resistances.
A special input circuit provides protection against accidental connection of
power-line voltages up to 240VAC.

OM5-WBS
Strain Gage Input Modules, Wide Bandwidth
FEATURES
The OM5-WBS modules are designed with a completely isolated computer
side circuit which can be floated to 50V from Power Common, pin 16. This
complete isolation means that no connection is required between I/O
Common and Power Common for proper operation of the output switch. If
desired, the output switch can be turned on continuously by simply
connecting pin 22, the Read-Enable pin to I/O Common, pin 19.
● INTERFACES TO 100Ω THRU 10kΩ, FULL-BRIDGE, HALF-BRIDGE,
OR QUARTER-BRIDGE STRAIN GAGES
● HIGH LEVEL VOLTAGE OUTPUTS
● 1500Vrms TRANSFORMER ISOLATION
The OM5-WBS can interface to full-bridge or half-bridge transducers with
a nominal resistance of 100Ω to 10kΩ. A matched pair of bridge-
completion resistors (to 1mV at +10V excitation) allows use of low cost
half-bridge or quarter-bridge transducers (Figures 2, 3, 4). The 10kHz
bandwidth allows measurement of high speed processes such as vibration
analysis.
●
ANSI/IEEE C37.90.1-1989 TRANSIENT PROTECTION
● INPUT PROTECTED TO 240VAC CONTINUOUS
● FULLY ISOLATED EXCITATION SUPPLY
● 100dB CMR
Strain Gage excitation is provided from the module by a very stable 10V
or 3.333V source. The excitation supply is fully isolated, allowing the
amplifier inputs to operate over the full range of the excitation voltage. This
feature offers significant flexibility in real world applications. Full scale
sensitivities of 2mV/V, 3mV/V or 10mV/V are offered as standard. With 10V
excitation, this results in 20mV, 30mV or 100mV full scale input range
producing 5V full scale output.

The input signal is processed through a pre-amplifier on the field side of
the isolation barrier. This pre-amplifier has a gain-bandwidth product of
5MHz and is bandwidth limited to 10kHz. After amplification, the input
signal is chopped by a proprietary chopper circuit. Isolation is provided by
transformer coupling, again using a proprietary technique to suppress
transmission of common mode spikes or surges. The module is powered
from +5VDC, 5%.

DESCRIPTION
Each OM5-WBS Strain Gage input module provides a single channel of
strain gage input which is filtered, isolated, amplified, and converted to a
high level analog voltage output (Figure 1). This voltage output is logic
switch controlled, which allows these modules to share a common analog
bus without the requirement of external multiplexers.
Special input circuits provide protection of the signal inputs and the
isolated excitation supply up to 240VAC.

OM5-IVI
Current Output Modules
DESCRIPTION
FEATURES
Each OM5-IVI current output module provides a single channel of analog
output. The track-and-hold circuit in the input stage can be operated in a
hold mode where one DAC can supply many output modules, or a track
mode where one DAC is dedicated to each module. In addition to the track-
and-hold circuit, each module provides signal buffering, isolation, filtering,
and conversion to a high level current output (Figure 1).
● ACCEPTS HIGH LEVEL VOLTAGE OR PROCESS CURRENT INPUT
● UNIPOLAR OR BIPOLAR CURRENT OUTPUT
● 1500Vrms TRANSFORMER ISOLATION
●
ANSI/IEEE C37.90.1-1989 TRANSIENT PROTECTION
● OUTPUT PROTECTED TO 240VAC CONTINUOUS
● 110dB CMR
Setting of the track or hold mode is controlled by the logic state of WR EN\,
module pin 23. When pin 23 is low, the track mode is enabled. If pin 23
is open or high, the hold mode is enabled. The module is designed with a
completely isolated computer side circuit which can be floated to 50V
from Power Common, pin 16. This complete isolation means that no
connection is required between I/O Common and Power Common for
proper operation of the track and hold circuit. For a low state, simply
connect pin 23, the Write-Enable pin, to I/O Common, pin 19.
● 400Hz SIGNAL BANDWIDTH
● 0.05% ACCURACY
● 0.02% LINEARITY
● CSA CERTIFIED, FM APPROVED, CE COMPLIANT
● MIX AND MATCH OM5 TYPES ON BACKPANEL
The OM5-BP-16-MUX backpanels allow host computer control of the WR
EN\ control line, which allows multiplexing of one host DAC to up to 64
OM5-IVI output modules. During power-up, the output remains at 0mA for
100ms on all models, which allows the track-and-hold circuit to be
initialized.
A special circuit in the output stage of the module provides protection
against accidental connection of power-line voltages up to 240VAC.
