4-Channel 5V Relay Module – Opto-Isolated, High-Level Trigger

Control Multiple Devices with One Reliable Module

This 4-Channel Relay Module allows your microcontroller (Arduino, ESP32, Raspberry Pi, etc.) to control up to 4 high-voltage devices like bulbs, fans, pumps, or motors. Each relay is rated for AC 250V / 10A or DC 30V / 10A, making it suitable for both residential and industrial applications.

The module features opto-isolated relays for safety and signal separation, and it works on 5V logic. It supports high-level trigger, meaning the relay is activated when the input pin is set high (logic 1).

Perfect for home automation, smart appliance control, security systems, and IoT projects.
