Time Delay Relays

2917450 Application Field and Working Principle

Time delay relays are electronic devices that help to control the sequence of a variety of operations by delaying the activation time of connected devices. Time delay relays can be divided into two categories: one-shot and multi-shot delay relays. The 2917450 is a one-shot time delay relay.

Application Field

The 2917450 time delay relay can be used in various applications in different industries, such as their use in industrial automation and control systems for controlling motors, pumps, fans, and compressors; for example in process control systems. Additionally, they can be used for load shedding and load balancing, temperature control, safety management systems, and to control electrical circuits. This type of time delay relay might also be used in automotive and domestic, commercial, and industrial electrical applications to control lighting systems, heating, and ventilation systems, amongst other uses.

Working Principle

The working principle and function of a one-shot time delay relay is that the contact closes when the supply voltage is applied, and the time delay is initiated. During the time delay period, the contact remains closed. When the stored time delay is complete, the contact opens, and the process is complete. This type of relay is commonly used in industrial automation and control systems, as well as in other applications, in order to control circuits, pumps, and motors, amongst other devices.

The 2917450 time delay relay is a one-shot type of time delay relay, and works on the same principle as other time delay relays. It is a 120 Volt AC grounded relay, with a nominal voltage rating of 12.8 Volts DC. When an input voltage is applied to the relay, an adjustable timer initially begins to count down. When the timer reaches zero, the relay energizes the output. The minimum and maximum time delay can be adjusted, meaning that it is possible to adjust the delay time from 0.1 second to 99 hours, 99 minutes, and 99 seconds. The end of the time delay is indicated by the LED lighting and the relay activating.

Conclusion

In conclusion, the 2917450 time delay relay is a one-shot type of time delay relay, which is used in various applications in different industries. When the supply voltage is applied, the delay time begins to count down, and when the timer reaches zero, the relay energizes the output. The time delay can be adjusted from 0.1 second to 99 hours, 99 minutes, and 99 seconds. This type of relay is commonly used to control circuits, pumps, and motors, amongst other connected devices.
