Description of Relay Module 1 Channel 5V
The Relay Module 1 Channel 5V is a compact electromechanical switching module designed to control high-voltage or high-current loads using a 5V control signal. It supports both AC and DC switching with a load capacity of up to 10A, making it suitable for automation and embedded applications.
The module features a single-channel relay output, standard 3-pin control interface (VCC, GND, IN), and an onboard status LED for easy operation monitoring. Screw terminals ensure secure load connections.
With its compact PCB design and mounting holes, it is ideal for Arduino projects, industrial control systems, and home automation setups.

Working Principle
When a 5V signal is applied to the IN pin, the relay coil is energized. This activates the internal switch mechanism, changing the contact state:
COM connects to NO when activated
COM connects to NC when deactivated
This allows low-voltage digital systems to safely control high-voltage appliances such as lights, fans, motors, and other electrical loads.
Applications
Arduino and microcontroller projects
Home automation systems
Industrial automation control
IoT-based switching systems
Motor and pump control
Smart switching circuits
Security and alarm systems
