Hello. I am having a similar problem. What I am attempting to do is to use a contact closure and confirm that a device has actuated. I have wired it so that the DI is the current source, through the contact to the ground. This tests out correctly (switches the I/O) using the LJ test function so I believe that my channels are configured properly. However, DF does not seem to be reading the signal.
The other (but related) problem I am having is that the LED device works differently than I think it should. Again, my intent is that the LED goes on when the contact closes. Please advise where I am going wrong. The email I sent to support (no response yet) is attached.
