Time Delay Relays

Time delay relays are a type of relay that offers delay for a certain amount of time between the actuation of a switch and the triggering of an output. Time delay relays are used extensively in industry, automation, and sensing applications. H3JA-8A AC100-120 10M is a type of time delay relay manufactured by OMRON. In this article, we will discuss the application field and working principle of this relay.

Application Field

The H3JA-8A AC100-120 10M time delay relay is designed primarily for use in the industrial field, most notably when precision timing and accuracy is necessary. These types of relays are often used in automation, sensing, and industrial control for applications such as motor control, signal processing, sensor detection, as well as other temperature and humidity sensing applications. Additionally, the H3JA-8A AC100-120 10M is widely used in applications where a specific amount of time is required to achieve a desired effect. The on-delay, off-delay, and cyclic time functions can be used for different applications. For example, when an electric gate is opened or closed, the off-delay and on-delay functions are used in order to keep the gate open or close for the predetermined amount of time.

Working Principle

The H3JA-8A AC100-120 10M time delay relay operates based on a specific set of physical principles. It uses an electrically energized, spring-loaded solenoid to control the duration of the delay. The solenoid is embedded in a coil and energized when the input signal is received. Upon actuation, the solenoid pulls a switch open or closed to initiate the timer. The relay then triggers the output after a specified amount of time. The timing sequence can be adjusted by and set to the required value. The H3JA-8A AC100-120 10M has a high degree of accuracy and repeatability, making it an ideal choice for precise, time-critical applications.

Conclusion

The H3JA-8A AC100-120 10M is a time delay relay manufactured by OMRON that is designed for industrial applications. The relay is most commonly used when precision timing and accuracy is necessary, and is often used in automation, sensing, and industrial control applications. The relay operates based on electrically energized, spring-loaded solenoids that pull a switch open or closed to initiate the timer, which triggers the output after a predetermined amount of time. The H3JA-8A AC100-120 10M time delay relay is a reliable and accurate solution for precise, time-critical applications.
