Power relays are electric devices which are widely used to control circuits remotely, as they reduce power consumption by eliminating the need for high-power manually operated switches. The NC4D-DC12V is a power relay that is designed to handle currents of over 2 amps. Its application field and working principle will be discussed in this article.

Application Field

The NC4D-DC12V relay is a general purpose relay for controlling logics, motor control, pumps and fans in a variety of applications. It can switch both AC and DC loads, and is suitable for controlling resistive, inductive and capacitive loads. The relay can be used in a wide range of industrial, commercial and residential applications, such as motor controllers, movement detectors, alarm systems, automatic doors, remote controls, robots, audio equipment, and so on.

Working Principle

The NC4D-DC12V relay is essentially an electromechanical switch. It works by allowing a low-power current from the power supply (normally 12 volts DC) to pass through a coil, thus energizing a magnet that pulls the armature down, which in turn opens or closes the contacts of the relay. The contacts will remain in their position as long as the current is flowing through the coil, so the relay has to be reset whenever the power is disconnected. This is done by either manually pressing on the armature or through a reset circuit.

The NC4D-DC12V relay can be used in either normally open (NO) or normally closed (NC) configurations. In a normally open configuration, the contacts of the relay are normally open and will close when power is applied to the coil. In a normally closed configuration, the contacts are normally closed and will open when power is applied to the coil. The purpose of the relay is usually to allow current to be switched between two different circuits.

Conclusion

The NC4D-DC12V relay is a general purpose power relay designed to handle currents of over 2 amps. It is suitable for controlling a wide variety of loads, and can be used in either normally open or normally closed configurations. The relay works by allowing a low-power current to energize a magnet that activates the armature, opening or closing the contacts of the relay. It is a reliable and useful device for controlling circuits remotely.
