The type and function of the relay
The following are the same as the "
The role of the relay: as a control element, summed up, the relay has the following 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. The following are the same as the "
2) Enlarge: For example, sensitive relays, intermediate relays, etc., with a very small amount of control, you can control the power of the circuit. The following are the same as the "
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. The following are the same as the "
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.
Relays Wave device
The following are the same as the "
The relay is an automatic switching element with isolation function, which is widely used in remote control, telemetry, communication, automatic control, electromechanical integration and power electronic equipment, is one of the most important control components. The following are the same as the "
The relay has a sensing mechanism (input part) that can reflect the input variables (such as current, voltage, power, impedance, frequency, temperature, pressure, speed, light, etc.). It can realize " (Output section) between the input portion and the output portion of the relay, and an intermediate mechanism (driving section) for coupling and isolating the input amount, the function processing and driving the output section.
