Used it as an interface between a QSYS GPIO and a contact closure display lift control. Sixteen display lifts grouped into six channels. Bought this 8 channel unit. Unit worked perfectly. Has a convenient LED to indicate power and then each relay has an LED to indicate if it's actuated. You can trigger off of a high signal or low, and the relays offer both normally open and normally closed connections. Will buy again.

Works like a champ, after I re soldered a leg on the optoisolator for relay 1. Works perfectly for my microcontroller. 5 stars because I'm back up and running on my automated house controls.

strong clicks even with low current signal wires. Signal inputs of 3.7v, 5v, and 12v working. Make sure the DC in voltage for the board is at the expected 12v.Whats cool about these relays if you connect the hot 12v of a switch into one of the inputs, then set jumper to LOW for that relay... whenever that switch is activated and the circuit is complete, so will the relay.

Works as needed. I’ve bought a few of these and never had a problem.

Using this with an ESP32 controller to activate 5 sprinkler zones. Relays activate fine on 3.3v signal. I am running 24V through the main relay contacts to active the sprinkler valves. Has been running over a year with no problems.

Bought this module to control 16 outlets via a PLC. Over 10k cycles and not a single issue so far, can't complain for such a low cost set of relays. Only thing that would make this perfect is if it came with nylon stand-off's and screws, but that is just me being nit-picky.
