1CH Relay Module

Safe and Reliable High-Voltage Control

This 1-channel relay module is an indispensable tool for controlling high-voltage devices with a low-voltage microcontroller signal. Operating seamlessly with a 5V trigger, it integrates an optocoupler (optoisolator) that ensures electrical isolation between your microcontroller and the high-voltage circuitry. This design prioritizes safety, protecting not only your devices but also yourself from potential electrical hazards during operation.

Versatile Applications to Simplify Your Projects

With the ability to handle both AC and DC loads, this relay module is suited for a broad range of applications, including switching lights, fans, motors, and other household or industrial appliances. Whether you’re developing a home automation system or embarking on an industrial prototyping project, this module provides the versatility and reliability you need to bring your ideas to life.

Convenient Design for Easy Installation

Designed for user convenience, the relay incorporates an onboard LED indicator that clearly displays the ON/OFF status of the module for instant, visual feedback. This ensures ease of monitoring, particularly during testing or troubleshooting. Additionally, all connections are made via robust screw terminals to guarantee secure and flawless wiring, and the tool-free setup simplifies both temporary prototyping and permanent installations.

Whether you’re an electronics hobbyist or a seasoned professional designing circuits, this 1-channel relay module offers the ideal combination of performance, safety, and user-friendly operation. Add it to your toolkit and streamline your project development today!
