HJ4-L-DC48V

Power Relays, Over 2 Amps

The HJ4-L-DC48V is a power relay that is suitable for applications requiring higher current rating than normal. It can handle up to 2 amperes of current and is designed to minimize electromagnetic interference. This type of power relay is ideal for applications that involve direct current, precision switching and measuring, and automotive devices.

Application Fields of the HJ4-L-DC48V

The HJ4-L-DC48V power relay can be used in a variety of applications, including renewable energy systems, telecommunications systems, industrial automation, automotive, medical, and home automation applications. Its precision switching and measuring capabilities are especially suitable for these application fields.

In renewable energy systems, the HJ4-L-DC48V can be used to replace traditional contactors, thus allowing for more efficient energy management. It can also be used in telecommunications systems for remote-controlled switching and routing of electrical signals.

In industrial automation, the HJ4-L-DC48V is used to control high-current loads, such as motors and pumps, and as a sensing device for positioning and tensioning of product assemblies. In automotive systems, it can be used to control signals like solenoid and speed sensors. In the medical field, it can be used to control power, signal, and load switching for medical devices.

Working Principle of the HJ4-L-DC48V

The HJ4-L-DC48V is an electromechanical device that works by using a coil to create a magnetic field. When the coil is energized, it creates a magnetic field which acts on an armature, causing it to move and make contact with a set of electrical contacts. This opens the electrical circuit and allows current to flow through. When the coil is de-energized, the armature moves back, returning the contacts to their original positions and closing the circuit.

The HJ4-L-DC48V power relay can be used as either a set/reset type device, where the coil is energized to open the contacts, or as a latching device, where the energized coil will hold the contacts open until de-energized. The HJ4-L-DC48V can also be used as a switch for measuring applications by connecting it to an AC or DC voltage source and connecting two leads to the contacts.

Conclusion

The HJ4-L-DC48V power relay is an excellent choice for applications requiring higher amperage than normal. It is suitable for direct current applications, precision switching and measuring, and automotive uses. The HJ4-L-DC48V works by using an electromechanical device consisting of an armature and a coil to create a magnetic field which opens or closes contacts. It can be used as either a set/reset or a latching device, and as a switch for measuring purposes.
