## Description

This 4-channel relay module allows you to control up to four independent circuits using a microcontroller such as Arduino, Raspberry Pi, or other MCU boards. Each relay channel has an LED indicator that shows the current output state, making it easy to monitor which relays are active. The modular design makes it simple to integrate into home automation, lighting control, and equipment switching projects. Each relay can switch loads up to 250V AC or 30V DC. Key Features 4 Independent Channels – Control four separate circuits LED Status Indicators – Visual feedback for each relay state High Switching Capacity – Up to 250V AC / 30V DC TTL Control – Compatible with 5V, 12V, and 24V logic levels Compact Design – 50 × 70 × 15mm board Specifications Channels – 4 Drive Current – 20mA Control Signal – 5V / 12V / 24V TTL level Max Switching Voltage – 250V AC / 30V DC Dimensions – 50 × 70 × 15mm Ideal For Home automation and lighting control Equipment and appliance switching Arduino and microcontroller projects Industrial control applications Package Contents 1× 4-channel relay module Warning: This module switches mains voltage. Exercise extreme caution when working with high-voltage circuits. Ensure all connections are properly insulated and follow local electrical safety regulations.
