So I decided to go ahead and use one of the xACs I had to trigger my garage door. I initially bought 3, one for each of my bikes, but after doing the first one I decided to see what other projects I could use them for. I ended up having to replace the one on the bike after I rode in a storm and the waterproof compartment wasn’t so waterproof, so that leaves me with 1 left.
Yesterday I tried installing it but the relay wouldn’t trigger. I thought perhaps the DPDT I used was a bit large and the trigger current might have been too much so I ordered a pack of basic 12V SPDT marketed for auto use.
Well, these aren’t triggering either. I’ve tried two different power supplies, and both will trigger the relay no problem by themselves, but when I wire up the xAC it’s no good. I get the red LED on and measurements at the trigger wire show 7.3V when attached to a load (the relay), but 12V when left off. Do I just have a dud or…? Any help would be appreciated.
PS 12V -------> xAC red
PS GND --------> relay pin 85 and xAC black
xAC white ---------> relay pin 86
