how to detect relay ON/OFF state with Analog Input of PCI 6221 card

Solved!
Go to solution

It works perfect with your setting JB.

 

Although, I am using an AI, because I have all the de DI occupied.

 

Ah, and the relay is driven by an external device, I just wanted to check how is it set.

 

Thank you very much.

An AI to check if a contact is ON or OFF is a quite "expensive" solution but obviously, if there is no remaining DI...
