What am I missing? I just put together two of these. I’m running each one off of its own power supply (one of your 5vds usb power supplies), which is stated at 1A out. I definitely have 5vdc coming into the terminal on the beefcake, but neither of the units are switching. No click, no led, nothing.
I’m not doing anything weird; I’m using each relay to control a 120 A outlet. So, I have my hot (black) connected to the load, and it goes to an outlet. The other side of the outlet goes to the white return wire. I’m slaving off of the 120 A input to drive the power supply, but that shouldn’t affect the relay. It’s all pretty simple stuff, so I figure I must be missing something or doing something stupid.
Thanks in advance for any help!
