Relay 1725156-1 is a kind of electromagnetic relay, typically made up of an electromagnetic structure, which rapidly opens and closes the circuit to protect or control some other circuit. The basic structure of this kind of relay is composed of an iron core or an iron yoke, a coil, an armature and a contact system. As long as the control system sends a switching signal, the coil and the control system form a closed magnetic flux path. The flux interacts with the armature, so the armature is energized to do the movement, and then the contact system of the armature is opened or closed according to the features of the contact.

The application field of 1725156-1 relay is extensive. In particular, it is widely used in machine control and automatic control circuit. The relay can be used to control the opening and closing of motor, solenoid valve, solenoid, heater, capacitor, lighting circuit and so on. Therefore, it can be seen that it is suitable for a variety of electrical circuits, and can play the role of protection, control, conversion and so on. At the same time, the 1725156-1 relay can also be applied to the switching and control of actuators, such as electro-thermal actuators, electromagnetic actuators, mechanical actuators, etc.

The working principle of 1725156-1 relay is also relatively simple. Generally speaking, the working process of the relay contains two steps, which are the forward excitation stage and the reverse excitation stage. In the forward excitation stage, the signal is sent out through the control circuit, and the coil current of the relay is energized by the control signal, so that the armature is attracted by the electromagnetic force. When the armature is attracted to a certain position, the contact system of the armature will be closed, and the normally closed contact will be opened, so as to achieve the purpose of opening and closing the circuit.

After the relay is closed, its coil will produce the reverse excitation effect. At this time, the relay contact system is opened and the circuit is reset. In addition, there is an electromagnetic latch effect in the relay, so that when the forward excitation is disconnected, the contact system will remain in the closed state after completing the forward excitation, and a constant current will be reserved in the coil. Thus, the two states of open and close are maintained in the circuit, which facilitates the on and off switching of the circuit.

In summary, the 1725156-1 relay is a kind of electromagnetic relay with wide application field and simple working principle. It can be used in machine control and automatic control circuit to control the on and off of electrical circuit. And thanks to its electromagnetic latch effect, it can maintain the two states of open and close in the circuit for a long time. Therefore, 1725156-1 relay is very popular among engineers and ordinary people.
