4-Channel 5V Relay Module

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.

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.

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.
