Relay Modules

Relay modules are electronic devices that consist of one or more relays, typically electromechanical relays, housed in a compact module. These modules are designed to interface between control signals, such as digital signals from a microcontroller or PLC, and the electrical circuit being controlled. They serve as a convenient and reliable way to switch power or control signals in various industrial applications.

A relay module typically has an input side and an output side. The input side is connected to the control signal source, such as an Arduino Uno or a microcontroller. It receives the digital signal and activates the relay's coil, which in turn switches the electrical contacts on the output side. The output side is connected to the devices or circuits that need to be controlled, such as lights, motors, or other electrical loads.

Relay modules offer several features and advantages. They provide galvanic isolation between the control signal and the controlled circuit, ensuring safety and preventing signal interference. Some modules may include diodes to suppress voltage spikes or protect the control circuit from back EMF generated by inductive loads like motors. Relay modules also offer the convenience of pre-wired connections, making them easy to install and integrate into projects.
