5V Relay Module – 1 Channel 10A Control Board

The 5V relay module is a reliable and easy-to-use control board designed for safely switching high-voltage or high-current devices using low-voltage control signals. This single-channel relay board is widely used in home automation, industrial control, and DIY electronics projects where safe and isolated power switching is required.

This 5V relay module features a low-level trigger input, allowing it to be activated directly from microcontrollers such as Arduino, ESP8266, ESP32, Raspberry Pi, and other logic control boards. The onboard optocoupler provides electrical isolation between the control circuit and the load, improving safety and reducing electrical noise interference.

Rated for up to 10A, the relay can control AC and DC loads such as lights, motors, pumps, fans, and appliances. The module includes clearly marked terminals for NO (Normally Open), NC (Normally Closed), and COM connections, making wiring simple and error-free. An LED indicator shows the relay status in real time, helping during testing and troubleshooting.

Built with high-quality components, this single channel relay board ensures stable performance and long service life. Its compact PCB design allows easy installation in control panels and project enclosures. Whether you are building a smart home system, an automation controller, or an educational electronics project, this relay module delivers dependable power control.

Overall, the 5V relay module is an essential component for switching and isolating electrical loads safely. Its optocoupler protection, low trigger requirement, and robust relay rating make it suitable for both beginners and professionals.
