4 CHANNEL RELAY 5V SHIELD
4 channel 5V relay shield for Arduino. Controls high-voltage AC/DC devices in automation and IoT projects.
Description
The 4 Channel Relay 5V Shield is a reliable power control module designed for Arduino and microcontroller-based automation projects. Operating at 5V logic, it allows safe control of high-voltage and high-current AC or DC loads through low-voltage signals. Each relay channel can be independently controlled, making it ideal for home automation, industrial control, robotics, and IoT applications. The shield format enables easy plug-and-play mounting on Arduino boards, reducing wiring complexity and improving project reliability.
