Time Delay Relays are a type of electromechanical contactor, used mainly to control electrical circuits with time after power is applied, such as delay on make, delay off make, delay on break, delay off break, and off-delay. The Omron H3CR-A8 AC100-240/DC100-125 is a particularly versatile and reliable type of time delay relay dedicated for use in electrical control circuits. In this article, we will discuss the various uses of the Omron H3CR-A8, as well as its working principle.

Applications

The Omron H3CR-A8 is designed for a variety of commercial and industrial settings, including factory control systems, HVAC control systems, pumping systems, building systems, and others. Its features and specifications make it an ideal choice for providing reliable and durable off-delay, on-delay, break-delay, and make-delay capabilities in a wide range of applications.

Product Features

The Omron H3CR-A8 employs advanced technology for maximum versatility and performance. It contains several control functions, such as:

• Zero-crossover, off-delay, on-delay, break-delay, make-delay, and bistable operations
• Time-limit ranges from 0.05-100s
• Universal voltage (AC100-240V/DC100-125V)
• Wide variety of control and set point inputs
• 30A relay contact
• Panel mounting and busbar mounting
• LED indicator for relay status

Working Principle

The Omron H3CR-A8 uses a simple yet effective principle to provide time-delay control. A voltage-sensitive relay activates a timer circuit when power is applied, which in turn activates a timer relay to control the operation of the circuit. This timer relay can be programmed to provide off-delay, on-delay, break-delay, or make-delay features, depending on the desired application. The time interval can be set between 0.05-100s, and the relay contact can handle up to 30A current.

Conclusion

Time Delay Relays are used extensively in a variety of industrial and commercial applications, and the Omron H3CR-A8 AC100-240/DC100-125 is an ideal choice for providing reliable and durable performance. Featuring a variety of control functions, including zero-crossover, off-delay, on-delay, break-delay, make-delay, and bistable operations, the H3CR-A8 is certainly a powerful and versatile time delay relay. Furthermore, its advanced protection against voltage peaks and LED status indicator make it a reliable and durable choice for any application.
