4-Channel Relay Module is a versatile electronic switching module designed to control four independent high-voltage or high-current loads using a low-voltage control signal from microcontrollers and development boards such as Arduino, ESP32, Raspberry Pi, and PLC systems.
Features:
* 4 independent relay channels
* Supports NO, NC and COM contacts
* Suitable for AC and DC load switching
* LED indicators for relay status
* Easy-to-connect screw terminals
* Compatible with Arduino, ESP32, Raspberry Pi and other controllers
* Ideal for controlling lights, motors, fans, pumps, solenoids and other electrical devices
Applications: Home automation, robotics, industrial control, IoT projects, electrical experiments, and automation systems.
