Detail Description

5V 4 Channel Relay Module is a reliable and versatile relay board designed to control four independent electrical loads using a 5V DC control signal. Each relay channel can switch AC or DC loads, making the module suitable for controlling lights, fans, pumps, motors, and household appliances.

The module typically includes optocoupler isolation, driver transistors, flyback diodes, and LED indicators for each channel, ensuring safe operation and clear status indication. It provides NO (Normally Open), NC (Normally Closed), and COM terminals for flexible wiring options.

This relay module is easy to interface with microcontrollers such as Arduino, ESP32, ESP8266, and Raspberry Pi. It is commonly used in home automation systems, IoT applications, industrial control, and DIY electronics projects.
