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.

power supply  
12V - 48VDC  
The signal input section consists of an Optocoupler isolated  
input (compatible with both current sink output and current  
Vcc  
source output).  
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.
