Time Delay Relays

Time Delay Relays are a type of electronic devices designed to sense a signal or activity and switch on or off certain activities after a predetermined amount of time. The H3JA-8C DC24 3S is one such example of a time delay relay. It is well suited for applications where a short or long delay sequence of operations is needed.

H3JA-8C DC24 3S application field

The H3JA-8C DC24 3S is a versatile time delay relay with a compact form factor. It can be used in a variety of applications, such as in industrial machinery, home automation, agricultural products, motors, pumps, and anything else requiring short or long time delays. Additionally, it is well-suited for applications where it is important to ensure accurate on/off timing and reliable operation.

Working Principle

The H3JA-8C DC24 3S time delay relay works by sensing a signal or activity in its input terminals, and then starting a timer to activate the load after a predetermined amount of time. It can either switch on (“ON-delay”) or off (“OFF-delay”) the load, depending on the setting and desired operation. The delay can be set to as low as 0.1 second, up to 99 hours 59 minutes in 0.01 second resolution. It can also be set to a “repeatable” delay, which will cycle after each time delay cycle is complete. This makes it ideal for applications which require repeated operation, such as motor starters.In addition to its timing function, the H3JA-8C DC24 3S is also equipped with auxiliary contacts that can be used to switch auxiliary functions or reset the time delay when needed. This makes it easy to control the timing function without the need for external circuitry.

Conclusion

The H3JA-8C DC24 3S is an excellent time delay relay, offering a long list of features, including a wide range of timing ranges, auxiliary contacts, and reliable operation. It is well-suited for many applications, making it a great choice for any project that requires accurate timing and reliable operation.
