Low-Level Trigger & 10A Contacts | Reliable 4-Channel Relay Board with Isolation

The 4-Channel Relay Module with Optocoupler Isolation (12 V) is a versatile and robust relay control board designed to operate four independent relays using a 12 V DC control voltage. With optocoupler isolation on each channel, the module protects your microcontroller or control system (Arduino, Raspberry Pi, PLC, etc.) from electrical noise and high-voltage transients when switching loads.

Each relay can switch high-voltage AC or DC devices making it suitable for home automation, industrial control, smart devices, and general electronics applications. On-board LED indicators provide relay status feedback, and easy-to-connect screw terminals ensure secure external device wiring.
