This unit survived a lot of experimentation until the time I accidentally reversed the DC inputs. Something popped and then it was over. In ordering a replacement, I found another vendor that had two in the package for almost the same price. Smart.

I was planning on using it to isolate my remote turn on. Relay 1 randomly turns on/off regardless of trigger state. Relay 2 seems to be functioning fine but the trigger input backfeeds 12v for about 15 seconds after the trigger signal is shut off. I think i got a bad one lol. For the price im not gonna bother with a refund, ill just use a relay.
