Jejpi23 Posted September 19, 2022 Report Share Posted September 19, 2022 Hello, I connected the plc and outputs as in attached file. But there is no voltage on any outputs any help ? The PLC outside the outputs works correctly (the LED on outputs are lid when they should bo no V ). Thx for any hint or help. Quote Link to comment Share on other sites More sharing options...

There won't be with no wiring connected. They are relays with a shared common. You either make the common - or +, but I always prefer to switch the +. So + goes to the CM# and on relay activation you get + at the relevant output. FYI, this is really electronics 101. Prior to doing further work, I suggest that you need to do some initial learning of some basics. cheers, Aus Quote Link to comment Share on other sites More sharing options...
