E10 Relay+ inputs

<< < (2/2)

support:
The LED flashes if there are current flowing through it but it does not mean that the input is recognized by the CPU. 

Are you able to measure the output from the vision system before you connect to the PLC's digital inputs? That way you can be sure what is the output voltage like when the output is ON and OFF.

Remember that the input to E10-Relay+ must be PNP type (i.e. between 18 to 24VDC when ON and 0-3V when OFF) so the output from the vision system must be compatible with the input requirement of the PLC for the CPU to recognize it.
