Power relays are electronic components designed to switch an electrical circuit either on or off, based on a set of specific instructions. The LY2F-AC110/120 is an example of a power relay that is typically used for the control of AC three-phase motors up to 2A, as well as for industrial and process control applications. In this article, we\'ll take a look at the application field and working principle of the LY2F-AC110/120 relay.

Application Field

The LY2F-AC110/120 is a two-pole power relay with a voltage of 180VAC and a current rating of up to 2A. It is typically used for the control of AC three-phase motor applications. The LY2F-AC110/120 features a slotted pin design which allows for easy installation into control cabinets. It is also designed to be dustproof and water spray-resistant.

The LY2F-AC110/120 is commonly used in industrial and process control applications, such as the automation of machine tools, pumps, compressors, and conveyer belts. It is also suitable for controlling the turning of pumps, blowers, and fans in industrial facilities. The LY2F-AC110/120 is commonly used in applications which require the activation of three-phase motors such as elevators, cranes, and other overhead conveyors.

Working Principle

The LY2F-AC110/120 relay is a bifurcated relay consisting of two separate parts - a coil and a main body. The coil is the part that delivers the current signal when energized and it is located on the right side of the main body. The LY2F-AC110/120 relay operates using electromagnetism. When a voltage is applied to the coil, it creates an electromagnetic field which pulls the armature of the main body towards it. This movement of the armature switches the circuit on or off depending on the position of the release handle.

The LY2F-AC 110/120 power relay features mechanical latching, meaning that the armature will stay in the position it was in when the coil was energized, until the release handle is manually actuated. This feature is useful for applications where a current needs to be maintained for an extended period of time. Furthermore, the LY2F-AC110/120 features a short-circuit protection that will safely shut off the circuit if a short circuit is detected.

Conclusion

The LY2F-AC110/120 relay is a two-pole power relay that is used for the control of AC three-phase motors up to 2A and in industrial and process control applications. It is a bifurcated relay consisting of a coil and a main body operating using electromagnetism. It features mechanical latching and short-circuit protection, making it a reliable and safe choice for industrial applications.
