LY1F-AC110/120 is an electrical component used to control and switch between electric circuits. Its strong durability and versatile performance make it suitable for a variety of applications, from industrial automation to automotive control systems. This article focuses on the application field and working principle of LY1F-AC110/120.

Application Field

LY1F-AC110/120 has a wide range of applications. In industrial automation, it is mainly used as a interlock control device, controlling the interlocking between circuits (relay contact) and protecting the circuits and equipment from damage due to overflow of current and voltage. In addition, it can also be used in electromechanical drive systems such as wind power, shipbuilding, petrochemical, water conservancy and other fields for controlling and interlocking the direction of motor rotation.

In the automotive industry, LY1F-AC110/120 is mainly used for controlling the automotive battery in many ways including controlling the power supply to the vehicle, the charging speed, the cranking of the engine, the electrical connection, and the alternator electrical connection. Furthermore, it can also be used to monitor and control the switches and warning lights, as well as to control the computerized systems.

LY1F-AC110/120 can also be used in aerospace products, such as providing triggers for arming and disarming system, controlling the motor\'s direction of rotation, and providing engine ignition signals.

Working Principle

The basic functional unit of the LY1F-AC110/120 is a contact that opens or closes the circuit. The contact is actuated by an electromagnet called the coil, and it opens when the current through the coil is decreased or disconnected. The contact can be opened manually or automatically with the help of a timer, switch, or electrical circuit.

The electrical components of the relay are the contacts, coil, and magnetic core, as well as a bobbin, transformer, and transformer driver. The contact is the primary electrical component that completes the electric circuit. The coil, its movable armature, and the core make up the electromagnet. The bobbin and transformer driver convert the input signals of the relay into electrical energy, which is then amplified by the transformer and used to actuate the coil.

When the relay is actuated, the electric current flows through the coil, generating an electromagnetic field which moves the armature, opening or closing the contact. Depending on the number of circuits and other parameters, the contact can be used to control a single circuit or multiple circuits. With multiple coil terminals, multiple circuits can be individually controlled by closing or opening their respective block contacts.

Conclusion

The LY1F-AC110/120 is a versatile electrical component ideally suited for a wide range of industrial, automotive, and aerospace applications. Its outstanding performance is due to its robust design, efficient operation, and versatile applications. The working principle of the relay is based on the electromagnetism generated when electric current passes through the coil, which then opens or closes the contact to set up or break the electric circuit.
