A relay module is an electronic device that uses an electromagnetic switch to control high-power circuits with a low-power signal, allowing for isolation between different parts of a system. It typically consists of a coil, armature, and contacts, where energizing the coil creates a magnetic field that moves the armature, closing or opening the contacts to control the connected load. Relay modules are commonly used in applications like home automation, industrial controls, and automotive systems to safely manage high-voltage operations.
