electrical & pneumatics help
I am trying to connect an old bot up with the new controller, and i am having trouble with the pneumatics. The nason pressure switch says "C" and "NC". These have to connect to digital I/O, but i need to know which one is +,-, or Signal. I had it working, but the wire had gotten hot. Can you tell me what the C and NC plug into.

thanks

PS, I am supposed to use PWM for this right?
