8 Channel 5V Relay Module

Overview

Take control of up to eight high-voltage devices with the MOKWN 8-Channel 5V Relay Module. This powerful relay board lets your microcontroller—whether it's an Arduino, ESP32, ESP8266, Raspberry Pi, STM32, or PIC—switch AC or DC loads independently. Each relay is rated for 10A at 250VAC or 30VDC, making it perfect for home automation, industrial control, robotics, and IoT projects. With optocoupler isolation, LED indicators, and screw terminals, this module delivers safe, reliable, and easy-to-use switching for makers and professionals alike.

MOKWN Recommendation

For reliable multi-device control, this 8-channel relay module is a top choice. Ensure your power supply can handle the total current draw of the relay coils (typically ~70mA per relay). If you're controlling AC loads, always follow safety guidelines and use proper enclosures. For most projects, we recommend pairing this with an Arduino Uno or ESP32 for easy integration.
