How to wire AC input just to test with switch

5 posts in this topic

Use to working on DC inputs, now I have a PLC I am playing with and the digital inputs are AC, can I still just wire a on/off switch to complete the circuit just for testing? This is a micrologix 1100.

Let's make sure your MicroLogix can handle AC. What's the part number of the PLC or module that you're hooking this to?

Then yes. Normally I would feed one side of the switch with 120VAC, take the other side of the switch to your input, then take the common for that input group to neutral.
