The mag of course needs the power removed with an OPEN, but the 624 sends a short. Anyone have an idea how I can change the short from the 624 to an OPEN. I was thinking of a small 12VDC relay, but maybe someone has run into this situation before, & can lend me some brain power. Thanks in advance. pfonman [email protected]
