In the world of electronics, a relay is a device that allows you to control a high-power electrical circuit using a low-power signal. A Dual Relay Module is a versatile component that features two relays in one package, providing the ability to control two independent circuits. This makes it an essential tool for applications that require switching between different devices, particularly in automation, home control, and robotics projects.
What is a Dual Relay Module? A Dual Relay Module is a compact and affordable component that incorporates two electromagnetic relays within a single unit. Each relay in the module functions as an electrically operated switch, allowing a low voltage signal, such as 5V from a microcontroller like an Arduino or Raspberry Pi, to control high-voltage devices like lights, fans, or home appliances. The key feature of the dual relay is its ability to control two different devices at the same time but independently of one another. By applying a control signal to each relay’s input, the module can activate or deactivate each relay based on the input commands.
