Hi Gents:
I met a problem with one of my 1769-OB32 module. Some of the channels suddenly malfunction -- The light indications for the channel are showing right status for ON/OFF, but the output voltage is wrong. When I force channel off, I can get 24VDC from the terminails, while when I force it on, I can measure 18VDC. Meanwhile, most of other channels are working right, that no voltage when off and 24VDC when it is on.
Any thoughts? Thank you.
