DC 24V Relay Module 8 Channel

These were low priced and worked perfectly for my project. I used this to take 12vdc mosfet driven outputs to contact closure to operate various low voltage loads. My only complaint is the screw terminals - they are a poorly cast (off-center) low quality phillips head screws that I was afraid would not stand up to frequently being tightened/loosened. My project was basically a one and done - so for my purposes it was fine.

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.

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.

El módulo quedó bien en mí equipo

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.

i linked this to a arduino nano as part of a localized room control. Works great for it.

this was perfect, highly sensitive on the input, which is what I was looking for, and the relays make a solid connection.

Works flawlessly. Excellent product.
