5V 4 Channel 4 Channel Relay Shield Shield Module

Description

A relay control expansion board designed for Arduino UNO R3 and Mega 2560 — that is the 5V 4 Channel Relay Shield Module. It allows you to independently control up to four AC or DC electrical loads, making it ideal for home automation, lighting systems, motors, pumps, fans, and other electronic projects.

Key Features

• 4 independent relay channels for controlling multiple electrical devices.
• Operating voltage: 5V DC.
• Designed as a relay shield for Arduino UNO R3 and compatible Arduino boards with a matching shield layout.
• Can also be used with the Arduino Mega 2560.
• Relay contact rating shown on the board: Up to 3A at 120V AC or 3A at 24V DC.
• Each relay provides NO (Normally Open), COM (Common), and NC (Normally Closed) connections.
• Convenient screw terminal blocks for easy load wiring.
• Onboard LED indicators show the operating status of each relay.
• Ideal for controlling lights, fans, motors, pumps, solenoid valves, and other AC/DC loads.
• Suitable for home automation, robotics, IoT, industrial control, and DIY electronics projects
