The Dual Relay Module is an essential electronic component used in automation and control systems. Its primary function is to control high-power devices such as home appliances, motors, or industrial equipment through a low-voltage signal. By using a low-voltage control signal, this module allows users to switch on and off devices that operate at much higher voltages or currents. This capability makes the Dual Relay Module an invaluable tool in the fields of robotics, home automation, and industrial control.
What is a Dual Relay Module? A relay is an electrical switch that operates by electromagnetism. When a control signal is applied, it energizes the electromagnet inside the relay, which in turn moves a set of contacts to either complete or break a circuit. The Dual Relay Module, as its name suggests, contains two such relays, making it possible to control two separate loads simultaneously. This feature is especially useful in applications where multiple devices need to be controlled independently but from a single controller, such as an Arduino or Raspberry Pi.
