Detail Description

The 12V 4 Channel Relay Module is a multi channel switching board designed to control multiple AC or DC loads using low voltage control signals from microcontrollers.

This relay module operates on 12V power supply and allows you to control 4 different devices like light, fan, motor, pump or appliances at the same time. It provides electrical isolation for safe switching and works perfectly with Arduino, ESP8266, ESP32, Raspberry Pi and other control boards.

Key Features:

• Operating Voltage: 12V relay module.

• Channel: 4 channel relay board.

• Multi Load Control: Controls 4 devices independently.

• Microcontroller Compatible: Works with Arduino, ESP32, Raspberry Pi.

• LED Indicators: Shows power and relay ON/OFF status.

• Easy Connection: Screw terminals for wiring output devices.

How it works:

1. Power the module with 12V supply.

2. Connect control signals to IN1-IN4 pins.

3. Each relay switches ON/OFF based on input signal.

4. Safely controls high voltage loads with isolation.

Applications:

• Arduino 4 channel relay control

• Smart home automation

• Multiple device switching system

• Lighting and fan control

• Motor and pump control

• DIY electronics and industrial projects
