Description

The Dual Relay Board allows you to control larger loads and devices like AC or DC motors, electromagnets, solenoids, and incandescent light bulbs.

Note: This board is not suitable for switching signals. It takes at least 100mA of current to bridge the oxide layer that forms on the relay contacts, and most signals will not meet this requirement. If you need to switch signals, check out the 1017 – PhidgetInterfaceKit 0/0/8.

 

The Dual Relay Board is a practical switching module designed for Arduino projects, automation systems, robotics applications, and embedded electronics development. This board allows microcontrollers to control external electrical devices such as lights, motors, fans, and other electronic loads safely.

Because automation systems often require switching high-power devices, the relay board provides reliable isolation between low-voltage control circuits and external equipment. In addition, the compact design makes installation easier in electronics enclosures and prototype systems.

Many students, makers, and engineers use this module for smart home systems and IoT automation projects. You can also combine it with the <a href=”/product/arduino-uno-r3/”>Arduino UNO R3</a> for easy relay control and switching applications.
