About this product
Two-channel 12V relay module with optocoupler isolation between the control inputs and the load side, helping protect delicate control circuitry. Its screw terminals (COM, NC, NO) make wiring simple. Triggered by a low logic signal, it can be controlled by Arduino, AVR, PIC and ARM microcontrollers.

Can I control it directly from a 5V Arduino?
The control inputs are logic-level signals, so an Arduino digital pin can drive them. Power the relay coils at their rated 12V and share a common ground between the Arduino and the module.
How should I wire the screw terminals?
Use COM for the common connection, NO to connect the load when the relay is active, and NC when the load should be connected while the relay is idle. Tighten the screws firmly and respect the rated load limits.
