Power Relays, Over 2 Amps – LY4I4-DC100/110 Application Field and Working Principle

The LY4I4-DC100/110 is high-performance power relay with high electrical performance and reliability. It features superior surge capacity of 10 times more than traditional relays. This device is a electromagnetic relay with a wide range of applications in power switching and control, providing both single and dual coil designs, suitable for various applications.

The LY4I4-DC100/110 application field includes control systems, AC/DC motor switching, power supply control, capacitor switching, field control, etc. This type of relay has an operating voltage range from 12V DC to 110V DC and a continuous current rating of 2A. It is designed for PCB mounting and features a built-in thermal protection system.

Working Principle

The LY4I4-DC100/110 is an electromagnetic relay which works based on the principle of electromagnetic attraction: when sufficient current is applied to its coil, a magnetic field is generated and causes the plunger to move, allowing the contacts to close. This creates a path for the current to flow towards the load. When the current is removed from the coil, the plunger returns to its original position and the contacts open, breaking the circuit.

The principle of operation can vary depending on the type of relay. The LY4I4-DC100/110 is a single-pole, double-throw (SPDT) relay. It has two sets of contacts: one is normally open (NO) and one is normally closed (NC). When power is applied to the coil, the normally open contacts close and create a connection between the two sets of contacts, allowing current to flow to the load, while the normally closed contacts open, breaking the connection.

Efficiency

The LY4I4-DC100/110 is a low power consumption relay with a high efficiency rating. It has an average coil power consumption of 3.5mW and a pick-up current of less than 150mA. It also has a power reduction feature that reduces the power consumption when the load is switched on. This feature helps to prolong the life of the device and also reduces overall energy consumption.
