Non-loop powered device to AB AI card

The Phoenix Contact device is a passive, loop powered isolator and the Moore Industries device is an active, powered isolator. If your I/O's input is not isolated, you may have a ground loop that will keep the PC unit from working. PC also makes powered isolators. I would talk to PC since you bought the PC isolator already. If you get not joy, the folks at Moore Industries are excellent at technical support. Give the people at Phoenix Contact a chance, first.

That may be the problem.
