S89R11AAC1-24

The S89R11AAC1-24 belongs to a family of power relays that are rated to switch loads of more than 2 amps. It is designed to operate in a wide range of temperatures, withstanding -40°C to +85°C. It is UL and CSA listed, and meets the highest reliability standards in the industry.

Overview

The S89R11AAC1-24 is a travel type relay designed with a miniature, compact shape. It is available in 24V and 12V versions with both normally open (N.O.) and normally closed (N.C.) contacts. It has an operating voltage range of 5 to 32 volts DC with pick-up of 4.5 volts and a drop-out of 2.5 volts. It has a contact resistance of 140 milliohms when the contacts are in the open position. The rated current is 2 A/24 VDC. It has a mechanical life of 10,000,000 operations and electrical life of 100,000 operations.

Typical Applications

The S89R11AAC1-24 is a versatile rack mounted power relay and is suitable for many applications. It can be used to automate a variety of mechanical equipment, such as conveyor systems, HVAC systems, robotic arms, packaging systems, and more. It can also be used in home automation applications, such as controlling lights or appliances. It is also commonly used in the automotive and aerospace industries for ignition, fuel injector, and powertrain control, as well as in medical equipment for safety control. Additionally, it is suitable for use in door entry systems, security systems, elevators, and more.

Working Principle

The S89R11AAC1-24 is designed with a high-force armature actuator and is functionally similar to a latching relay. When voltage is applied to the coil, the electrical arc energy creates a magneto-motive force which pulls the armature and activates the contacts. When de-energized, the force of the armature returns the contacts to the normal state. The armature is designed with two springs: one when the voltage is applied to keep the contacts closed, and the other when the voltage is released to keep the contacts open.

Safety Features

The S89R11AAC1-24 is designed with safety features that prevent malfunctions due to excessive current and voltage. The relay has a low temperature rise, a high contact resistance, and a powdered steel base that dissipates heat. It also has a high mechanical strength and a corrosion-resistant base to protect against environmental factors.

Conclusion

The S89R11AAC1-24 is an excellent choice for controlling a variety of mechanical, home automation, automotive, and aerospace applications. It is robust, reliable, and offers advanced safety features to protect against malfunctions. With its long mechanical and electrical life, it is an efficient and cost-effective way to control high-power loads.
