HJ4-AC48V-6

HJ4-AC48V-6 Application Field and Working Principle

The HJ4-AC48V-6 power relay is a high quality relay that is used in a wide variety of applications. This relay is often used in automation, industrial control, and embedded applications. The relay is typically used to provide an interface between two circuits, or to act as a switch for controlling the flow of power to a device.

The HJ4-AC48V-6 power relay has a 6-pin configuration, including a common pin, normally open pin, normally closed pin, two power supply pins, and an influence pin. The common terminal is connected to the outside, while the other pins are connected to the internal relay. The two power supply pins are usually connected to an input power supply to provide the power for the internal relay. The normally open pin is used as the control terminal, while the normally closed pin is connected to the other side of the circuit and is used as the output connection. The influence pin is used to adjust the contact action when the external circuit changes.

The HJ4-AC48V-6 power relay works by using an electromagnet as the controlling element. When the power supply pins are connected to a power source, the electromagnet will be energized, allowing the relay contacts to close. When the input voltage is removed, the electromagnet is deenergized, resulting in the contacts opening and the power flow being shut off. The influence pin can be used to adjust the current of the input voltage so that the relay contacts open or close depending on the current.

The HJ4-AC48V-6 power relay has a wide range of application fields, ranging from industrial control and automation to embedded applications. For instance, they can be used in DC motor controllers, industrial control systems, and various other embedded applications. They are also often used as flow switches in water tanks or pools, as well as temperature control systems.

In summary, the HJ4-AC48V-6 power relay is a reliable and versatile relay that can be used in a wide variety of applications. It has a 6-pin configuration, including a common pin, normally open pin, normally closed pin, two power supply pins, and an influence pin. The relay works by using an electromagnet as the controlling element, allowing the relay contacts to be opened or closed depending on the current of the input voltage. This relay is often used in industrial control, automation, and embedded applications, and is also used as flow switches and temperature control systems.
