24VDC 8 Channel Relay Module 20x4 Benzine | Portable alcohol detectorThis is a DC 24V 8 channel relay module is an electronic device that consists of 8 independent relay switches. Each switch can be controlled independently, allowing the module to switch multiple devices on and off simultaneously using a single control signal. The relay switches are electromechanical in nature, meaning that they use an electromagnetic field to control the flow of current through a circuit. The 8 channel relay module is commonly used in
