Customer Reviews (5.0 / 5 · 5 reviews)

Charlotte Y. ★★★★★

The NC and NO terminals on each channel make wiring a breeze, and the 5V trigger worked flawlessly with my Arduino on the first try. I’ve got four separate loads hooked up now, and the LEDs on each channel are a nice touch for quick status checks.

Edward Z. ★★★★★

The screw terminals are spaced just right for my jumper wires, and the LED indicators make it super easy to see which channel is active at a glance. I've got all four channels switching different 12V loads in my workbench setup, and they've been rock solid for two weeks straight.

James Y. ★★★★★

These relays clicked on and off reliably during my test run, and having both NO and NC terminals on each channel saved me a lot of extra wiring. Works exactly as described for controlling my low-voltage project loads.
