I have a 1734-oe2v +/- 10 volt card that drives a proportional valve. Its been in service for several years. today it quit outputting. The day shift electrical team replaced the card with no change. One electrician disabled the card then re enabled it and it started outputting again. four hours later it did the same. and again the electrician disabled/enabled and it started outputting again. Im not getting any faults or alarms on the card or the logix. Any Ideas?
