The relay is automatic switch components with isolation function, widely used inremote control, telemetry,
Communication, automatic control, electromechanical integration and power electronic devices, is one of the most important control element.
Relays are generally can reflect a certain input variables (such as current,voltage, power, frequency, impedance, temperature, pressure, speed, light etc.)induction mechanism (input); can the controlled circuit to realize the "pass", "off"control actuators (output) between the input part; and the output part of the relay, and coupling isolation of input, processing and output part of the middledrive (driving).
To sum up, the relay as control element, there are several effect:
1) expand the control range: for example, relay contact control signal reaches a certain value, can according to the different forms of contact group, at the same time, take off, multichannel circuit.
2) amplification: for example, sensitive relay, intermediate relay, with a very smallamount of control, circuit can control large power.
3) integrated signal: for example, when a plurality of control signals in the prescribed form input multi winding relay, after comparison, control effect to thepredetermined.
4) automatic, remote control, monitoring: for example, automatic device of relay and other electrical appliances together, can form a program control circuit, to realize automatic operation.
