What is the role of universal single-phase latching relay?


GRT508B 100A GENERAL PURPOSE SINGLE PHASE LATCHING RELAY. It has an interactive relationship between the control system (also called the input loop) and the controlled system (also called the output loop). Usually used in automated control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current.It is a kind of electronic device control element. It has control system software (also called input back to dao road) and controlled system software (also called output control loop). It is generally used in fully automatic control circuits. A kind of "control switch" to control a large amount of current. Therefore, it has the functions of automatic adjustment, safety maintenance, and circuit conversion in the circuit.Fully automatic electronic switches with protective functions are widely used in remote control, monitoring, communication, automatic control, mechatronics, and power engineering electronic products. It is one of the most important control components.1. Voltage and current conversion, original circuit 5V voltage, maximum 70mA current, 220V, 2A load can be transferred through the relay2. Realize the conversion between normally open and normally closed3. Realize remote control
