A 4 Channel Relay Module is an electronic device that consists of four relay channels, each capable of controlling a high-power device. The module typically has four input pins, four output pins, and a power supply pin. The input pins receive low-power signals from a microcontroller or other control devices, which then activate the corresponding relay channels, allowing high-power devices to be controlled.
