Using 24VDC Asco 4-Way Solenoid valves to supply air to actuators with NC/NO mechanical switches to indicate open/close position of each valve. How should the solenoid valves and limit switches be wired for control under PLC?
Thinking about running the solenoid through a relay first, but I'm pretty sure the modules should drive the solenoid with no issue. Better to be on the safe side I guess....
Yes, an interposing relay wouldn't hurt anything. You would also want to use diodes to protect your output from flyback from the relay coil or solenoid coil.
