I'm sure this is a common sense question but I have to ask since I've never wired a PLC.
I have a sensor with two wires. My PLC terminal has one wire. Am I correct in assuming that the + wire from the sensor goes to the PLC terminal and the - wire is connected to the common from the power supply to the PLC?
Thanks in advance.
