Hi
I have two directional pneumatic valves that have some sort of coils on them, when energized they let the air out through a port. What i'm not sure is how to connect them to my dc output card?
If i have an output card with transistors can i use a solid state relay since these coils on my valves are operating at 115VAC. How to connect the relay is it just simple as connecting "+" side of solid state relay to one of the outputs, and "-" on solid state relay to COM of PLC.
Thanks
