Product details This is a dual-channel relay module powered by 12 V DC and featuring optical isolation on each input channel to safeguard the controller or logic circuitry against noise, spikes or interference from the relay coil or load circuits. The module provides two separate relay channels; each relay is capable of switching moderate mains loads (up to 10 A), such as motors, lights, solenoids or other appliances. The inputs are opto-isolated, which means the trigger side (control logic) is isolated from the relay coil / contact side, improving safety and reducing chance of back-EMF, interference or ground-loop issues. Signal LEDs indicate the status of each relay, and screw-terminal blocks are used for load connections (Common, Normally Open, Normally Closed). Mounting holes on the PCB facilitate firm installation. Ideal for industrial-lite, automation, embedded / MCU-based control systems where you want two separate outputs controlled via 12 V logic input.
