Like other F&eIT series products, the module has a 35mm DIN
rail mounting mechanism as standard. A connection to a
controller module can be effected on a lateral, stack basis in a
unique configuration, which permits a simple, smart system
configuration without the need for a backplane board.

Output section
Figure below shows the output circuit for the interface section
of this product. The signal output section consists of an
Optocoupler isolated open collector output (current sink type).
An external power supply is therefore required to drive the
output section of this module.
The maximum output current rating per channel is 150 mA for
this product (at 12 - 24 VDC) or 50mA for this product (at 36 -
48 VDC). A surge voltage protection circuit (zener diode) is
provided for the output transistors of this module. When the
module drives relays, lamps, and other induction loads,
however, another surge voltage countermeasure should be
provided on the load side.
Signal Layout on the Interface Connector
The Module can be connected to an external device using a
12-pin connector that is provided on the Module face.

An external power supply is therefore
required to drive the input section of this module. The power
requirement for the <DIO-4/4(FIT)GY> or <DI-8(FIT)GY> is
about 8 mA per input channel at 24 VDC (about 4 mA at 12
VDC).

Setting a Device ID
The controller module distinguishes and keeps track of the
modules that are connected to it by assigning device IDs to
them. Each module, therefore, should be assigned a unique
ID.
A Device ID can be assigned in a 0 - 7 range, so that a
maximum of eight modules can be distinguished.
The factory setting for the Device ID is [0].
Setup Method
A Device ID can be set by turning the rotary switch that is
located on the module face.
A Device ID can be assigned by turning the switch.
