A dry contact is basically a relay. In this case, mine is NC. When my unit is reset and the relay is closed I see a 0 on the pin. When the relay goes open I see a 1 on the pin. When the relay closes again I still see a 1 on the pin. My question is why does the pin not go back to a 0? I hope that clears up my questiona little better. Sorry about that. Matt |
