Power Relays, Over 2 Amps – 8-1435537-4 Application Field and Working Principle

The power relays, specifically the 8-1435537-4, are well-known for their variety of options available as far as how they are utilized and their ability to handle amperages in excess of two amps in many cases. This article will discuss the application field of 8-1435537-4 as well as its working principle so that people are better informed about the use of these power relays.

Application Field of 8-1435537-4

The 8-1435537-4 power relays are used in many applications such as sound systems, industrial automation, machine controls, and HVAC systems. They are also used in medical equipment and automotive applications, to name a few. The 8-1435537-4 power relays offer a variety of options when it comes to the current ratings, which range from 10A for a single-throw contact configuration to 300A for a double-throw contact configuration. The contact material is made of silver for enhanced conductivity and durability. The 8-1435537-4 power relays are able to operate in environments with temperatures as low as -40°C and as high as 85°C with a DE rating, AC-15 rating, and a DC rating of 14 V. As the 8-1435537-4 power relays are equipped with LED indicator lamps, there is no need for an external current source in order to see if the contacts are closed or open. This is an important feature for applications in which time is of the essence.

Working Principle of 8-1435537-4

When it comes to the working principle of the 8-1435537-4 power relays, it is almost identical to all other types of relays. In its simplest form, the 8-1435537-4 power relays make use of an electromagnetic coil to close a set of electrical contacts when a certain amount of voltage is applied to the coil.When the set voltage is applied to the coil, a magnetic field is created, which pulls the main contact towards the coil as well as the plug-in contacts, thus reliably closing the entire circuit. The current that is able to flow through the closed contacts is determined by the current rating of the relay. Once the current stops flowing through the coil, the magnetic field dissipates allowing the spring-loaded contacts to open. This is the principle that power relays, including 8-1435537-4, use in order to isolate circuits with different current levels. Although the 8-1435537-4 power relays are designed with a DC operating voltage, when used with an AC application, they can still effectively switch currents up to three times their rated value. This is due to the fact that the AC current increases and decreases much more slowly when compared to DC, enabling the 8-1435537-4 power relays to switch the current much more quickly and more reliably.

Conclusion

The 8-1435537-4 power relays are well-known due to their ability to handle amperages well beyond two amps and their versatility when it comes to applications. In addition, their ability to operate in both AC and DC, at temperatures ranging from -40°C to 85°C, makes them an essential component for a variety of industrial and automotive applications. By understanding the application field and working principle of these power relays, people can make an informed decision as to whether the 8-1435537-4 is an appropriate choice for their specific application.
