How much current flows typically through a dry contact to a digital input module? Using 120VAC module and power.
I'm assuming around 30mA.
I'm wiring a Valves Open limit switch DI point and a Close limit switch DI point together on the common side.
I'm pretty sure I'm ok, but need some assurance that my .25Amp is sized correct. I see other designers jumper alot more and the plc panel function just fine.
