I/O Circuit and Wiring diagrams

Wiring diagram

Non-voltage contact or
NPN open-collector transistor
Low : 0 to 1 V
High: 4.5 to 30 V, or open

Note:
Terminal [2, 0 V of power supply, is isolated from 0 V of input / output circuitry for noise immunity. However, if you expect to share the power supply with the output loads, connect terminals [2] and [6] , terminals [2] and [10] , or terminals [2] and [20] to make 0 V common.

I/O circuit diagram

Note:
0 V of power supply is isolated from 0 V of input / output circuitry. To share the power supply with a load, both the 0 V terminals should be short-circuited.
Symbols・・・ D : Reverse supply polarity protection diode
ZD : Surge absorption zener diode
Tr : NPN output transistor
