Hello,
Forgive the basic question, but I've been having a hard time finding a clear answer to this online or otherwise. I'd really appreciate any help here!
This is still a theoretical problem at the moment. Let's say I've got a PLC operated machine that's running on a 480vAC power circuit and a 120vAC control circuit, and we're relying on the PLC's internal power supply (transformer/rectifier) to convert that control power to whatever we need.
I want to wire a start PB into this PLC. I know one side goes to an input terminal on the appropriate module. But what does the other side of the start pb connect to? Is there a neutral return on the module to connect to?
Once again, forgive my ignorance. I really appreciate any help!
