TL-SSR – 24V / 80A DC Unidirectional Solid State Relay (SSR)

Did not work, despite hooking it up exactly how I was supposed to. Always allowed electricity to flow through it even with the ground control wire not connected and hooking it up in the proper direction (in/out).

These are great relays.

I replaced some brick-type solid state relays with these after the original parts kept overheating. I've had zero problems with these. They seem to actually perform at the rated current capacity. They're feeding a set of motor controllers for thrusters on an underwater robot.
