Profile

Electromagnetic relay is an electronic control device, which has a control system (also known as the input circuit) and the control system (also known as the output circuit), usually used in automatic control circuit, it is actually using a smaller current, lower voltage to control a larger current a higher voltage "automatic switch." It plays in the automatic adjustment circuit, the role of security, conversion circuit.

application

Electromagnetic relays are bells, telephone and automatic control circuit means is an important component, and its essence is controlled by a solenoid switch, switch plays a similar role in the circuit: (1) low-voltage, low current high voltage control, strong current; (2) to achieve automatic control and remote manipulation.

Electromagnetic relay can use a low voltage and weak current of the control circuit to control the high voltage, high current operating circuit, and can realize the production automation and remote control. The electromagnetic relay is widely used in automatic control (such as refrigerators, automobiles, elevators, the machine in the control circuit) and communication fields.
