A HJ2-L-AC24V is an industrial relay used for general purpose switching. The typical applications include controlling pumps in water treatment systems or controlling machinery in industrial settings. It is important to understand the working principle of this type of relay before attempting any type of installation. This article will discuss the application field and working principle of this type of relay.

Power Relays, Over 2 Amps

HJ2-L-AC24V is classified as a power relay and operates on 24 volts AC. The relay can handle currents up to 2 amps. This type of relay is ideal for applications with a small power requirement or for systems requiring a low-voltage switch.

A HJ2-L-AC24V relay has normally open (NO) and normally closed (NC) contacts. The NO contact is used to control the power on or off, whereas the NC contact can be used as a safety switch or backup. The relay also has an optional LED indicator to show the status of the contact.

Working Principle

The working principle behind a HJ2-L-AC24V relay is relatively simple. When the relay is provided with an AC voltage, an electromagnet pulls a switch arm. This switch arm is connected to either the NO or the NC contact. When the relay receives the AC voltage, the switch arm will move according to its switch type. If the NO contact is energized, the switch arm will move to close the NO connection, and the circuit will be complete. If the NC contact is energized, the switch arm will move to close the NC connection, and the circuit will be open.

The trigger voltage that is required to activate the relay switch depends on the coil design, coil voltage, and contact current rating. If the coil voltage and the contact current rating is high, more voltage is needed to move the arm. This voltage is called the hold voltage, and it is important to ensure that the incoming AC voltage is higher than the hold voltage required to keep the relay energized. For example, if the hold voltage is 24 volts, then the incoming AC voltage must be greater than 24 volts.

Application Fields

The HJ2-L-AC24V relay is used in a wide variety of industrial and consumer applications. In industrial applications, it is commonly used to control pumps, fans, solenoids, motors, and other electrical components. The relay is used in consumer applications for home appliances such as dishwashers, refrigerators, and washing machines.

It can also be used to control lighting fixtures. Because of its reliability and low-voltage requirements, it is a popular choice for many installations.

In addition, the HJ2-L-AC24V relay is a cost-effective solution because it does not require a lot of power to operate. This makes it a great choice for applications where there is limited space or budget. In addition, its small size and low voltage requirements make it a suitable choice for many applications.

Conclusion

The HJ2-L-AC24V relay is a popular choice for many industrial and consumer applications. It is reliable, cost effective, and can handle currents up to 2 amps. Its working principle is relatively simple; when the relay receives an AC voltage, its switch arm will move to either the NO or the NC contact. In addition, its small size and low voltage requirement make it ideal for applications where space or budget is limited.
