5V Relays

Control high-power devices safely with our range of 5V relay modules designed for Arduino, Raspberry Pi, ESP32, and other 5V microcontroller projects. These relay modules feature optocoupler isolation to protect your control circuits from voltage spikes and electrical noise.

Our 5V relay collection includes single-channel modules for simple on/off switching, multi-channel options like our 2 channel, 4 channel, 8 channel, and 16 channel relay modules for complex automation projects. Each relay can switch loads up to 10A at AC 250V or DC 30V, making them ideal for controlling lights, motors, pumps, heaters, and appliances.

Perfect for home automation, IoT projects, robotics, and industrial control systems. All modules work seamlessly with popular Arduino boards, Raspberry Pi, and ESP32 development boards.
