2-7 Peripheral control wiring
2-7-1 Input/output circuit wiring
The input/output circuit to control the external signal such as external emergency stop input and relay
changeover signal output is wired.
The input/output circuit for each unit is as follows.
Input circuit Output circuit
For a switch or relay to be wired, use a switch or relay that satisfies the input/output (voltage, current)
conditions.
Interface name Selection example
For digital input signal (CN23,CN9)
Use a minute signal switch which is stably contacted and operated even with low
voltage or current
<Example> OMRON: G2A, G6B type, MY type, LY type
For digital output signal (CN9)
Use a compact relay operated with rating of 24VDC, 50mA or less.
<Example> OMROM: G6B type, MY type
