Description:
The 4 Channel 5V Relay Module 10A is a reliable and versatile switching module designed to control high-voltage AC and DC loads using low-voltage microcontrollers. Featuring four independent relay channels, this module allows Arduino, ESP32, Raspberry Pi, STM32, and other development boards to safely operate appliances, motors, pumps, lights, and industrial equipment.
Each relay supports switching loads up to 10A, making it suitable for home automation, robotics, IoT projects, security systems, and industrial control applications. The onboard optocoupler isolation helps protect sensitive control circuits from electrical noise and voltage spikes, ensuring stable and safe operation. LED indicators provide real-time status monitoring for each relay channel, while screw terminals enable secure and convenient wiring.
