Overview

Add reliable, isolated switching to your next electronics project with this DC relay module board. Built around an optocoupler input stage, it lets a low-power signal from a microcontroller safely control higher-current loads without electrical noise bleeding back into your logic circuit.

Available in 1, 2, 4, 6 and 8 channel versions and in 5V, 12V and 24V coil options, this board is a practical building block for Arduino, Raspberry Pi and other DIY automation setups. The high/low level trigger design makes wiring straightforward: just bring power to VCC and GND, then drive the IN pin to switch the relay.
