Power relays are devices used to control, switch and distribute electrical power in various systems. With their ability to accurately control power delivery even in sensitive equipment, they help to ensure that electrical networks, processes and equipment are operated safely and effectively. The HC4D-L-DC12V-D is a power relay designed for use with low voltages, such as 12 volts DC, to provide power control signals for various applications. It is a high capacity, dual coil latching relay that is both reliable and cost-effective.

The HC4D-L-DC12V-D is designed for automation and switching applications in residential and commercial buildings, as well as many industrial control applications. It is often used to switch power in motor control circuits, lighting and alarms circuits, pumps and HVAC systems. It can also be used for switching higher currents and requires fewer contacts than a conventional relay because it has a double coil. It is also used in the automotive industry, where its high temperature ratings make it suitable for extended operation.

The working principle of the HC4D-L-DC12V-D is based on its dual coil latching design. The relay consists of two coils, a primary and a secondary. The primary coil is energized when power is applied through the relay’s DC power supply. This draws the armature of the internal switch into the primary coil, closing its contacts and allowing current to flow through the secondary coil. When the primary coil is de-energized the contacts on the secondary coil open and the armature moves away, which prevents the current from flowing though the relay.

This latching action makes the HC4D-L-DC12V-D ideal for applications such as manual pump control, where the pump can be switched on and off with just a single press of the button. It is also useful for remote control applications and can be used to switch an elevator or similar device between different floors without the need for a continuous current supply.

The HC4D-L-DC12V-D is rated for use with currents ranging from 2 amps to 10 amps, making it suitable for a wide range of applications. It has a contact resistance of 25 milliohms and can withstand shock and vibration up to a maximum operating temperature of 60°C. Its stainless steel housing makes it resistant to corrosion, and its low-profile design is suitable for use in tight spaces. Overall, the HC4D-L-DC12V-D is an excellent choice for a variety of low power switching applications.
