The KUHP-5D51-24, or 5.9A 24 VDC relay, falls into the category of Power Relays, Over 2 Amps. This device is a high-performance sealed power relay specifically designed for industrial applications.

Applications

The KUHP-5D51-24 provides safe isolation between the controlled and controlling circuits. Its high switching capacity (maximum switching power: 600W; maximum switching current: 5.9A; maximum switching voltage: 24 VDC) is applicable for industry, commercial, and consumer automation applications, such as home appliances, automotive electronics, industrial apps and more.

Working Principle

The KUHP-5D51-24 consists of a sealed plastic housing containing a copper-wound coil energized by an electromagnetic impulse. This impulse reacts with an armature attached to a set of contacts. When the coil is energized, an electromagnetic field causes the armature to move, allowing the normally open (NO) contact to close and the normally closed (NC) contact to open. When the coil is de-energized, the armature returns to its original position, re-opening the NO contact and closing the NC contact. This action transmits power to the connected load.

The sealed plastic housing not only protects the KUHP-5D51-24 from the elements, it also prevents any build-up of moisture or dirt that could cause it to corrode or be otherwise damaged over time. As a result, it is highly reliable and suitable for insensitive environments.

Mounting Options

The KUHP-5D51-24 can be used with either PCBs or socket mounts. The PCB is the preferred method for applications such as ATMs, vending machines, card reader access devices, and other point-of-sale terminals where a low-height footprint is desired. The socket mount provides an easy way to connect the relay to the application\'s wiring, eliminating the need for a printed circuit board and providing greater flexibility in the application\'s design.

Technical Specifications

The KUHP-5D51-24 has a wide variety of technical specifications, ranging from contact ratings to pick-up times. The maximum contact rating is 5A 277 VAC and the maximum carrying current is 5.9A 24 VDC. The time delay is 50 mS (maximum). Additional features include a dust- and humidity-proof rating of IP67, an operating temperature between -20°C and +85°C, and a UL approved contact material.

Conclusion

The KUHP-5D51-24 is a powerful, reliable, and cost-effective relay suitable for a wide range of industrial applications. Its compact size and robust performance make it an ideal choice for applications ranging from consumer electronics to industrial automation.
