Do you know the basic working principle of signal relay

The basic working principle of the signal relay, the single phase meter shunt is a commonly used device in the automatic control system. It is generally used to connect and disconnect the circuit. It releases the card to issue control commands and reflect the status of the equipment. After the equipment returns to normal, it passes the reset signal The card to release the signal is an important original part of the automatic control and remote control circuit.

Signal relay function:

　　 1. Expand the control range. For example, when the control signal of a multi-contact relay reaches a certain value, multiple circuits can be switched, opened, and connected at the same time according to different forms of contact groups.

　　2, zoom in. For example, sensitive relays, intermediate relays, etc., can control a circuit with a large power with a very small control quantity.

　　 3. Integrated signal. For example, when multiple control signals are input to a multi-winding relay in a prescribed form, they can achieve the predetermined control effect after comparison and integration.

　　4, automatic, remote control, monitoring. For example, the relay on the automatic device and other electrical appliances can form a program control circuit to realize automatic operation.

Principle of signal relay: It is a relay that receives the impulse current sent by the impulse relay to make the light sign, buzzer and electric bell ring.

There are many types of signal relays. The signal relays are used for monitoring and protection, and are often used in the secondary protection circuit of the high-voltage cabinet.

What is the function of the signal relay? This is the basic working principle of the signal relay. The signal relay is a commonly used electrical appliance in the automatic control system. It is used to connect and disconnect the circuit to issue control commands and reflect the status of the equipment. It constitutes an automatic control and remote control circuit and is an important part of railway signals.
