The relay has several effects:
1) to expand the control range: For example, multi-contact relay control signal to a certain value, you can press the contact group of different forms, while switching, breaking, connected to multiple circuits.
2) Enlarge: For example, sensitive relays, intermediate relays, etc., with a very small amount of control, you can control the power of the circuit.
3) Integrated signal: For example, when a plurality of control signals are input into a multi-winding relay in a prescribed form, the comparison is carried out to achieve a predetermined control effect.
4) Automatic, remote control, monitoring: For example, the relay on the automatic device together with other electrical appliances, can be programmed to control the line, in order to achieve automated operation.
The relay is an electrical control device. It has a control system (also known as the input circuit) and the control system (also known as the output circuit) between the interaction.
Usually used in automated control circuits, it is actually a small current to control the operation of a large current "automatic switch". So in the circuit plays an automatic adjustment, security protection, conversion circuit and so on.
A relay is an electrical appliance that turns on or off a circuit based on physical changes such as voltage, current, temperature, speed, or time. The main function of the relay is protection and control.
