Hi
I have a connection from PLC cabinet to MOV for remote operation
Details as below :
Driving Control Voltage : 120VAC
Cable from PLC to MOV for command (DO) and feedback (DI) : 19C
Observation :
MOV operation and feedback from remote mode in PLC is fine, no issues.
One observation is, when put multimeter probe between one core of the cable and to ground ,it measures around 45VAC.This voltage is enough to lit feedback LED. Need to understand
1. What is this voltage /Why do see measure this voltage
2. Is this harmful for PLC
3. Can we eliminate this
