I found this in a going outta business computer hardware store. I got it for free but it had no instructions. I hooked up a 12v transformer to the two isolated screw terminals and it still powers up and everything. The other screw terminals are the 4 channel inputs. + and common. Any help would be appreciated. I think I could have a little fun with this relay once I figure out how to run it haha.
Anything helps! Thank you!
