SSR SERIES MODULES AND BACKPLANES  
This guide describes the mechanical and electrical aspects of the solid state  
relay (SSR) Series modules and backplanes. It also describes how to install  
and configure them for use with National Instruments data acquisition  
(DAQ) devices. The SSR Series consists of the following digital signal  
conditioning modules and backplanes:

Introduction  
You can use the SSR Series digital signal conditioning modules with your  
PC and National Instruments DAQ devices to control or sense voltages  
from field devices. The SSR modules are high-performance, fully  
encapsulated devices that interface the PC to field devices via optical  
isolation. These modules plug into one of the SSR backplanes, which are  
available with 8-, 16-, 24-, and 32-module capacities. Each backplane has  
screw terminals for field connections. A 50-pin connector connects the  
backplane to the DAQ device. The backplanes also have light emitting  
diodes (LEDs) that indicate the status of each SSR module.

The dropout voltage and current specifications for the output modules are  
given in the Manufacturer Data Sheets section. For most control  
applications, such as controlling motors or lamps, these requirements are  
not difficult to meet.  
A second difference between these output modules and conventional relays  
is that they do not turn off completely. A small leakage current flows all the  
time even in the off state. For most control applications, this current causes  
no problems.  
Output SSR modules require a certain amount of current from the digital  
control for the module to turn on. If the DAQ device sends a logic high  
signal, the output module turns off and no current flows. If the DAQ device  
sends a logic low signal, the output module turns on and current flows from  
the +DC control or Vcc to the -DC control. This current must be large  
enough to turn on the output module. If the DAQ device or digital control  
cannot sink enough current through the -DC control, the module does not  
turn on. Refer to Table 1 to find the minimum logic control current required  
to turn on each output module.

Note  
Make sure you pair the output module with a DAQ device that provides sufficient  
control current. For example, the following National Instruments DAQ devices do  
not work reliably with the SSR-OAC-5 and SSR-OAC-5A: the DIO-24 (6503),  
DIO-96 (6508), Lab/1200 Series, AT-MIO-16D/AT-MIO-16DE extended DIO  
lines, DAQCard-700, PC-LPM-16, and PC-AO-2DC.  
SSR Backplanes  
This section describes the SSR backplane in detail including connection,  
function, SSR module installation, and field connections.  
Connection  
All four SSR backplanes function similarly, but they accommodate a  
different number of modules. Each backplane has a special cabling scheme  
to maximize the number of modules in use.

The SSR backplanes are divided into ports of eight modules each. The  
8-, 16-, 24-, and 32-module backplanes have one, two, three, and four  
ports respectively.  
Table 2 shows backplanes that need an interface to convert the digital  
input/output (DIO) lines to map correctly. Table 2 also shows cables that  
are available for connecting DAQ devices and SSR backplanes. Refer to the  
National Instruments catalogue if your system is not listed in the table.

2This adapter is available separately. See the National Instruments Catalogue for information about cabling to connect an  
SC-205X to your DAQ device.  
NA means not applicable  
If you need an interface, use the SC-205X Series devices. You can connect  
backplanes that do not need an SC-205X Series device directly to a DAQ  
device because the modules map directly to one or more DIO ports.  
The SC-205X Series devices break out different DIO ports for use with  
different products. For information on connecting, mounting, and cabling  
your DIO ports using the SC-205X, see your SC-205X Series User Manual.

Caution  
Do not attempt to connect the SSR backplane to a host computer DAQ device for  
which it was not designed. Such connections can damage any or all SSR modules,  
the host computer, and the DAQ device. National Instruments is not liable for any  
damages resulting from incorrect connections.  
!
The 32-module backplane connects the PCLK1 (OUT1) and PCLK2 (OUT2)  
signals of the DIO-32HS (6533) device to ground. When using a 32- module  
backplane, do not configure a device for any mode that uses the PCLK1 or PCLK2  
line. Specifically, do not configure the DIO-32HS (6533) for burst handshaking  
mode, which uses PCLK, or write any data to port 4, which is the port that includes  
the PCLK1 and PCLK2 lines. Incorrect configuration can damage the host  
computer and your DAQ device. National Instruments is not liable for any  
damages resulting from incorrect configuration.  
Configuring the Power Supply  
This section describes how to configure the SSR backplane jumpers to get  
+5 VDC power to the SSR modules.  
You can power the SSR module backplanes by either the DAQ device or an  
external power supply. You need external power when connecting to a DAQ  
device that does not supply external power or when the power needed for  
the SSR modules and any other accessories exceeds the power supplied by  
the DAQ device. Different DAQ devices supply different amounts of  
power; for example many supply 1 A. See the specifications of your device  
for more information.  
The current needed for the SSR modules and accessories is the sum of the  
maximum logic supply current of all SSR modules connected to the DAQ  
device plus any other current needed by accessories connected to the same  
DAQ device.  
To configure the SSR module backplane for external power or DAQ device  
power you need to set a jumper on the backplane. This can be just a wire  
jumper or it can be a fuse. If you use a wire jumper, you need to fuse the  
logic power supply somewhere before the backplane.  
Figures 1 through 7 show the backplane power jumper locations, which are  
not clearly marked on the backplane. Install only one jumper at a time. If  
you install both jumpers, you can damage the supply or SSR module  
backplane.

Note  
The Crouzet 32 module backplane has no position on the backplane for either a  
fuse or jumper. You must add a power supply fuse elsewhere before connecting the  
power. Use a fuse that is suitable for your application.  
SSR Module Installation  
You can install the SSR modules by plugging each module into one of the  
positions on an SSR backplane. They are keyed so they cannot be inserted  
incorrectly. Many DAQ devices require that all DIO lines in a port be  
configured either for input or output. In these cases make sure you install  
the same type of SSR module, input or output, for each line in the port.  
You can mix input and output SSR modules on the mounting rack only if  
you connect them to different I/O ports or you use a DAQ device that allows  
mixed line directions within a port. Do not attach input modules to output  
lines under any circumstances or you can damage the SSR modules or the  
DAQ device.  
LEDs  
Each module position of an SSR backplane has a status LED to show the  
status of the SSR module logic line. For input modules, the LED is on when  
the load voltage is within the specified range of the SSR module. For the  
SSR Series Modules and Backplanes

output modules the LED is on when the module is turned on. See the  
Manufacturer Data Sheets section for further information.  
Signal Connections  
Connect external devices to the SSR modules using the screw terminals.  
Two screw terminals are dedicated to each module. Screw terminal  
pair 1 and 2 are for module 0, terminal pair 3 and 4 are for module 1, and  
so on. In the case of the DC modules, the odd numbered screw terminal is  
always the positive terminal and the even numbered screw terminal is the  
negative terminal. On the load side, a 5 A fuse protects each module. This  
fuse is always located on the even numbered or negative screw terminal to  
the module. Figures 8 through 11 show typical signal connections. See the  
Manufacturer Data Sheets section for further information.
