Gravity: Digital 16A Relay Module Shipping:4-6 Days including the original (green) versionsA relay is an electrically operated switch, which has a control system (also known as the input circuit) and the controlled system (also known as the output circuit), usually used in automatic control circuit. It is actually "automatic switch", using a small electric current to control a larger current. Therefore, the relay has the effects on the automatic automatic adjustment, security, conversion circuit in the circuit and so on. Relays are used
