Power Relays, Over 2 Amps, are used to control and protect a variety of electrical applications. They act as an interface between the system being controlled and the user. The HC4-HL-AC120V is one such type of power relay, designed to handle high current applications, up to 120V and up to 2A.

The HC4-HL-AC120V is typically used in consumer electronics, in HVAC (Heating, Ventilation, and Air Conditioning) systems, and in several different types of industrial settings. In the home, this type of power relay can be used to control lighting fixtures, remotely closing and opening the power switch. In the office, it can be used to regulate power supply and prevent surges. In industrial settings, it can be used to control the flow of electric power, ensuring proper up-time and safety.

The HC4-HL-AC120V power relay is designed for high current applications, meaning it can handle a maximum current rating of up to 120V and 2A. It is equipped with a built-in thermal overload protector, designed to protect the relay from overloading and overheating. Like many power relays, the HC4-HL-AC120V is often used to act as a switch between two circuits, allowing one circuit to turn another one on or off. This makes them a popular choice for process control and automation applications.

It is also equipped with an integrated LED indicator, which is used to indicate that the relay is switched on or off. The relay also features an adjustable coil voltage range, allowing users to choose the coil voltage that is most suitable for their application.

The working principle of the HC4-HL-AC120V is relatively simple. When the current through the coil reaches a certain level, the magnetic field created by the coil will attract a moving contactor, which acts as the switch. When this contactor is attracted, it will break or close the circuit. When the current is switched off, the contactor is released, and the circuit is opened again. This switching action will repeat, ultimately providing a constant current flow to the application.

The HC4-HL-AC120V power relay is designed to handle the higher current loads in a variety of applications, such as automation, control, and HVAC systems. They also feature high reliability and a long life expectancy. With their adjustable coil voltage and integrated LED indicator, they are a great choice for a wide range of current-sensing applications.
