Relay is an electrical control device, is when the input (excitation) changes to meet the requirements, in the electrical output circuit to make the controlled amount of a predetermined step change of an electrical appliance. It has an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop). Usually used in the automatic control circuit, it is actually a small current to control the operation of a large current of an "automatic switch". Therefore, it plays the role of automatic regulation, safety protection and conversion circuit in the circuit.
A relay is an electrical control device that can give a specified input and hold it long enough to cause a predetermined step change in the controlled quantity in the electrical output circuit. When the input is reduced to a certain level and maintained for a long enough time, it can be restored to the initial state.
