The Dual Relay Module is an essential component in various electronic projects and systems, providing a versatile and efficient way to control high-power devices using low-power control signals. It is widely used in automation, robotics, smart homes, and industrial control systems, thanks to its simplicity, reliability, and cost-effectiveness. In this article, we will delve into the features, applications, and working principles of the Dual Relay Module, showcasing its significance in modern electronics.
What is a Dual Relay Module? A Dual Relay Module is an electronic board equipped with two relays that can control two separate high-power devices. Relays, in general, are electrically operated switches used to open or close circuits by using a low-voltage control signal. This makes them ideal for controlling devices that operate at higher voltages, such as household appliances, motors, and lights, which typically cannot be directly controlled by microcontrollers or low-power circuits. The Dual Relay Module allows users to control two devices independently using a single microcontroller or control board. It works by receiving control signals (usually 5V or 12V) and switching the high-voltage side of the relay accordingly. This enables users to manage various appliances and devices, even if they require significantly higher voltage and current levels.
