Product Description
Products Description
Relay is an electronic control device, it has a control system (also known as the input loop) and the controlled system (also known as the output loop), usually used in automatic control circuit, it is actually a small current to control the larger current of an "automatic switch". Therefore, it plays the role of automatic regulation, safety protection and conversion circuit in the circuit.
When the change of excitation quantity in the input loop reaches the specified value, the automatic circuit control device can make the controlled quantity in the output loop undergo a predetermined step change. It has an induction mechanism that can reflect an external excitation quantity (electric or non-electric), an executive mechanism that can achieve "on" and "off" control of the controlled circuit, and an intermediate comparison mechanism that can compare, judge and convert the size of the excitation quantity. Relays are widely used in the fields of automatic control, remote control and telemetry, communication, broadcasting and aerospace technology, and play a role in controlling, protecting, regulating and transmitting information.
1. Structure of electromagnetic relay. The general electromagnetic relay is composed of electromagnetic system, contact system, transmission and recovery mechanism. 2.The electromagnetic system is the induction mechanism, which is assembled by the magnetic circuit system and coil composed of the iron core made of soft magnetic material, the choke iron and the armature iron.
3.The contact system is the actuator, which is assembled by different forms of contact reed or contact sheet used as contact in a certain insulating way.
4.The transmission and restoration mechanism is the intermediate comparison mechanism, and the transmission mechanism that realizes the relay action refers to the mechanism that transmits the armature motion to the contact reed when the coil is excited. Generally, it is directly driven by the contact reed connected with the armature or indirectly driven by the movement of the armature. It is a transmission form in which the armature directly drives the contact reed 3 to move. The restoring mechanism refers to the mechanism that restores the armature to its original position when the coil is deexcited. Except for a few relays that achieve armature recovery by contacting the total pressure of the system, it is generally achieved by restoring the reed or spring. The action of the recovery mechanism is realized by the recovery spring.
5.When the voltage or current of the relay coil reaches a certain value (x,), the armature draws, so that the normally open contact closes the relay characteristic and the contact loop is connected. When the coil voltage or current gradually decreases to a certain value (x,), the armature is released, the normally open contact is also disconnected, and the contact loop is cut off. Electromagnetic relays use the voltage or current in the coil to control the voltage or current in the contact loop when When the electrical signal in the coil changes to a certain value, the electrical signal of the contact loop presents a step change (from min to max). This characteristic is called the relay characteristic of the relay, also known as the input-output characteristic of the relay.
