Electromechanical relays are one of the best, most reliable, and cost-effective methods of controlling and isolating currents in electrical circuits. Over the years, technological advancements in the design and manufacture of these components has seen their usage expand into many industries, giving rise to a great variety of power relays and other devices capable of handling currents of over 2 Amps. In this article, we will be taking a look at the 8897100000 application field and working principle.

Of the many varied types of power relay currently available, the 8897100000 is a particularly versatile device that is suitable for a variety of applications. It is a 120V AC, 4 Pole, UL CSA approved, industrial grade SPDT relay, typically used for switching higher currents than that of a general purpose relay. With a current capacity of up to 20A, it is ideal for an array of commercial and industrial applications, including HVAC, security, lighting, vending, motor control, and more.

Working Principle

The 8897100000 operates on the principle of electro-magnetic induction. When power is applied to the terminals, a magnetic field is generated within the device. This, in turn, creates a force that attracts the moving armature, activating the included relay switch. When the power is removed from the relay, the electromagnetism dissipates, overcomes by a spring force inside the device, allowing the armature to reset and deactivating the contacts.

This device meets stringent requirements for industrial grade relays. It is designed with an environmental protection rating of IP30 (degree of protection against penetration of solid objects) and features a coil surge suppression of 500V. Other features include an Ambient temperature range of -20°C (-4°F) to +85°C (+185°F), as well as contact materials certified for use in certain military and automotive applications.

Applications

As mentioned, the 8897100000 is an ideal choice for applications in which the switching of high current is required. In HVAC systems, this device is often used for fan, motor, relay, and valve control. It can also be used for thermostat control and temperature/humidity control, as well as in automations systems that require an always-on solution. Additionally, these devices are perfect for applications with a high noise environment, since they are designed to minimize the level of susceptibility.

The 8897100000 is also a great choice for motor control systems, such as those used in vending machines and food processing equipment. Light and security applications can also benefit from the use of this device, as it is able to switch enough current to power multiple lights on a single circuit.

Conclusion

In conclusion, the 8897100000 power relay is a highly-versatile and cost-effective solution for a wide range of applications, including HVAC, motor control, lighting, and security. This device is UL/CSA approved, featuring a current capacity of up to 20A and a coil surge suppression of 500V. With its magnetic working principle and high resistance to external interference, this device is the perfect choice for commercial and industrial applications, and is guaranteed to provide years of reliable and trouble-free service.
