understanding the dual relay module and its applications
Release time:2025-09-22 19:27:13
The Dual Relay Module is a versatile electronic component that plays a crucial role in controlling high-power electrical devices via low-power microcontrollers like Arduino, Raspberry Pi, or other similar platforms. It acts as an interface between the microcontroller and external circuits, enabling safe and efficient control of devices that require a higher current than the microcontroller can supply directly. In this article, we will explore what a Dual Relay Module is, its working principle, applications, and why it is so widely used in various industries.
What is a Dual Relay Module?
A Dual Relay Module is an integrated circuit board that contains two relays. These relays are electrically controlled switches that open or close a circuit to control the flow of electricity to an external device. The key advantage of using a relay is that it allows a low-power signal from a microcontroller to control high-voltage devices (typically 120V or 220V) such as lights, motors, or home appliances. Each relay in the module can be controlled independently, which is why the term “dual” is used—indicating two relays that can perform separate switching functions.
