Power Relays, Over 2 Amps

LY2-AC110/120 is a solenoid multipurpose power relay available with a wide range of features. Commonly referred to as a "mini-power relay," these versatile power relays are used both for switching power in a variety of applications and as an indicator of the status of some component of the system. Understanding the capabilities of LY2-AC110/120 and the applications for which the mini-power relay is best suited is key to incorporating these valuable components into your application.

Application Field

LY2-AC110/120 mini-power relay is suitable in applications where low to moderate-high current is required reliably and safely. With its power switching applications, it is commonly used in lighting switching, control and protective circuits, or multiple motor control applications. It can also be used in medical device applications, where the design cycle depends on meeting safety, performance, and system requirements, and working within the confines of demanding timelines.

The mini-power relay is also well-suited for embedded computing applications, especially in computing devices with limited physical space or for wireless remote control applications. With its small size and flexible mounting options, the mini-power relay can be used in various industrial sectors, such as elevator control, power distribution, fire alarm, HVAC, normal open-close switching, and other similar commercial and industrial applications.

Working Principle

The working principle of the LY2-AC110/120 relay is based on the transfer of mechanical energy into the opening and closing of switch contacts. The highly reliable switching action is provided by a magnetic field generated by a coil energized with direct current, also known as a solenoid. In this type of operation, when the current is applied to the coil, a magnetic field is created. The force of this magnetic field causes the moving parts within the relay to move and actuate the switch contacts, breaking or making the connection of the electrical circuit.

The normal open-close switching characteristic of the LY2-AC110/120 relay makes it ideal for a range of applications that need a reliable and safe switching of power. With its low rating current the mini-power relay is suitable for use in all kinds of control circuits, especially in low voltage or micro power applications. The relay also offers flexibility, as it can be mounted in both vertical and horizontal orientation in the system.

Aside from its normal open-close operation, the LY2-AC110/120 mini-power relay also offers “no-volt release” and “no-volt protective” features. The no-volt release holds the contacts in the open position until connected to the circuit, while the no-volt protective prevents contact sparking due to the switching of high-voltage or inductive loads.

The LY2-AC110/120 mini-power relay is a reliable and cost-effective solution for switching power in industrial, commercial, medical, and other applications requiring low to moderate current capacity. With its compact size, flexibility in orientation, and robust features, it is an ideal component for use in embedded computing, remote control, and other integrated systems where power switching and indicator functionality is required.
