GenerL question. I dont have the part number infront of me. But i am looking at a valve with an M12 connection on it. Pin1 - not used, pin 2 - 24VDC A, pin 3 - 0vdc, pin 4 24vdc B.
Generally if i am switching safety voltage i would do it on the 24vdc side. But due to limited space i am wondering if it is still safe if the 0vdc side is switched. There is no ground wire that the 24VDC would use as an alternate path.
Just curious since i have never wired a machine this way.
Thanks for any advice!
