About Relay Modules

A relay module is an electronic device used to control and switch power to other electrical loads. These modules usually consist of several relays, a power supply, a control circuit, and several necessary connectors on a printed circuit board. Relay modules are commonly used in industrial, commercial and even home applications where access to a remotely operated switch is needed. Common uses include controlling lights, motors, solenoids, and other electrical loads.
