Question:

Input relay, the role of output relay.

Input relay, the role of output relay.

Answer:

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. (Such as current, voltage, power, impedance, frequency, temperature, pressure, speed, light, etc.) of the sensing mechanism (input part); can control the circuit to achieve the " (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 portion, The

As a control element, summed up, the relay has the following effects: ..... 1) to expand the scope of control. For example, the multi-contact relay control signal to a certain value, you can press the contact group in different forms, while switching, breaking, connected to multiple circuits. ..... 2) zoom in. 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 predetermined form, the control effect is achieved by comparison. .... 4) automatic, remote control, monitoring. For example, the relay on the robotic device, along with other electrical appliances, can be programmed to control the line, enabling automated operation.

Factory specializing in the production of various types of time relay electromagnetic relay electronic relay high-power relay level relay solid-state relay high-power relay small relay timer counter relay. Relay is essentially a signal transmission of electrical appliances, it is based on the input signal to achieve different control purposes. The relay is typically used to turn on and off the control electronics (motor) Such as in the DC motor in the current relay, when the current is too small or too large, it detects the current signal after the control of the motor start and stop There are such as thermal relays, such as long-term overload of the motor leaving the temperature is too high, it will control the motor to stop
