Description of 4 Channel 5V Relay Module
Quick Overview
The 4 Channel 5V Relay Module offers a convenient way to control up to four high-voltage devices simultaneously using low-voltage logic circuits. This makes it a go-to solution for projects that demand multi-device coordination, such as smart homes, industrial automation, robotics, and more.
How It Works
The module consists of four electromagnetic relays, each with its own isolated control circuit. When a 5V signal is applied to any of the relay's control pins, it energizes the coil in that relay, creating a magnetic field that pulls the internal contacts together and allows current to flow in the connected high-voltage circuit.
Technical Specification
- Operating Voltage: 5V DC
