Product Description
Relay is an automatic switching element with an isolation function. It is widely used in remote control, telemetry, communication, automatic control, mechatronics, and power electronic equipment. It is one of the most important control elements.

The relay generally has an induction mechanism (input part) that can reflect certain input variables (such as current, voltage, power, impedance, frequency, temperature, pressure, speed, light, etc.); Between the input part and the output part of the relay, there is an intermediate mechanism (drive part) that couples and isolates the input quantity, processes the function and drives the output part.
As a control element, to sum up, the relay has the following functions:

1) Expand the control range: For example, when the control signal of a multi-contact relay reaches a certain value, it can switch, break, and connect multiple circuits at the same time according to different forms of contact groups.
2) Amplification: For example, sensitive relays, intermediate relays, etc., with a very small amount of control, can control circuits with high power.
3) Integrated signal: For example, when multiple control signals are input to the multi-winding relay in a specified form, the predetermined control effect is achieved after comparison and synthesis.
4) Automatic, remote control, monitoring: For example, the relay on the automatic device can form a program control circuit together with other electrical appliances to realize automatic operation.
