Time Delay Relays are an essential component of many commercial, industrial, and residential applications. Most are used for tasks such as timing cycle or delay on/off, overlapping, and/or sequential operations. It is a device that can sense an input signal of time and will then open or close its contact for controlling a circuit as the preset time has passed. It is also known as a delay-on-make or delay-on-break relay. Time Delay Relays (88256585) have numerous applications and can work with both pneumatic and electronic devices.

Application Field

Time Delay Relays are primarily used to control various machinery, small or high-powered motors, lightings, HVAC systems, ventilation fans, pumps, compressors, conveyor belts, and even access controls. Additionally, they can be used to control heavy-duty motor starters, PLCs, Sequencers, Three-Phase Controllers, and other control systems. When combined in their higher voltage capacity relays, they can also be used in lift control systems or other machinery remote-controlled operations.

Working Principle

When the time delay relay receives an input signal, the contact output will start counting. The relay will keep counting until the preset time has passed and then it will open or close its contact output depending on the design. When the time-delay has reached the preset time, the output will remain in that state until the energized reset button is released. This makes time delay relays a very reliable and safe component for various tasks that require a delay in operation.

Time delay relays can be configured in three different modes – Fixed Delay, Adjustable Delay, and Variable Delay. Fixed Delay relays are designed to activate at some predetermined time after receiving a signal, which can then be adjusted using external trim pots. Adjustable Delay relays are programmed to provide an adjustable output after connecting with an input signal. Variable Delay relays have a variable output delay that can be set with a wide range of settings and timing.

Conclusion

Time Delay Relays (88256585) are a great way to control various motor, lighting, and HVAC operations as they provide reliable and safe operation while operating with both pneumatic and electronic devices. They come in three different modes – Fixed Delay, Adjustable Delay, and Variable Delay – that can be used depending on the application needs. These relays are also used for tasks such as timing cycle or delay on/off, overlapping, and/or sequential operations.
