Time Delay Relays

Time Delay Relays are widely used in many industries for their precise set-up, dependable accuracy and improved performance. The relay offers a complete cycle when triggered, so it ensures a precise control over long time periods, which is especially beneficial in industrial applications. This article will discuss the application field and working principle of the H3JA-8A 12VDC 3H Time Delay Relay.

Application Field

The H3JA-8A 12VDC 3H Time Delay Relay is a perfect device for industrial applications where long delays are required. It can be used in start-stop applications, such as for process controls, emergency shutdowns, increased safety and energy saving. It is also useful in automotive, aerospace and other industries, allowing an exact control over precise time periods. The H3JA-8A is particularly suitable for industrial applications that require precision or strict accuracy over a longer period of time.

Working Principle

The relay works by delaying the output signal. When power is supplied to the relay it energizes a capacitor to the same voltage as the supply voltage. This creates a current that flows through the coil and establishes a magnetic field. When the start button is pressed, it supplies current to the coil, which induces a current in the armature, releasing the contacts. This starts the delay, and when the set time is reached, the coil’s current is cut off and the magnetic field is weakened allowing the armature to move back, breaking the contact and stopping the output. This is the basic working principle of the H3JA-8A 12VDC 3H Time Delay Relay.

Advantages

The H3JA-8A 12VDC 3H Time Delay Relay offers several advantages. It helps to save energy by delaying the output of power and operation. It also allows precise control over long time periods, making it ideal for industrial applications where accuracy is required. This relay has an adjustable timing range which can be tailored to a customer’s needs. It also has an adjustable contact timing range meaning the set time can be changed as required. Furthermore, it is a low-power device, and it is reliable and durable.

Conclusion

The H3JA-8A 12VDC 3H Time Delay Relay is an ideal device for industrial applications requiring accuracy and precise control over long time periods. It has many advantages such as adjustable timing range and adjustable contact timing range which can be changed as required. This relay is reliable and durable and helps to save energy.
