Time Delay Relays

Time Delay Relays, also known as TDRs, are devices that delay the operation of certain components in an electrical circuit or system. They are typically used as part of an automated process or machine control system to provide a desired delay or time interval before a process or operation is initiated. A TDR consists of a relay or contactor, timer, and power supply.

88256506 Application Field and Working Principle

The 88256506 is a time delay relay that can be used in a variety of applications. It is commonly used in switchgear and process control systems for power systems, automation systems, and industrial automation systems. This type of relay provides a delayed, on/off switching action which can be adjusted rapidly and accurately.

The 88256506 consists of a timer, relay, and power supply. The timer is also known as the "delay generator". It acts as a variable resistor which, when activated, produces a delay in the operation of the relay. The power supply is used to provide power to the relay and timer, and is usually 110V single phase or 240V three phase. The relay is rated for up to 25A/400VAC.

The working principle of the 88256506 is quite simple. When the power supply is turned on, the relay receives a signal from the timer. Depending on the setting of the timer, the relay will then wait for a certain amount of time (the delay) before switching on or off. When the delay time has passed, the relay will then switch its corresponding contact, activating the desired process or operation.

The 88256506 can be used in a wide variety of applications; some of the more common uses include starter circuits, lighting control systems, process control systems, and motor control systems. In starter circuits, the relay is used to delay the startup of motors to prevent excessive currents from occurring. It can also be used in lighting control systems to give lights “warm-up” time before they are switched on, and in process control systems to provide a delay between the start and end of an operation.

In addition to its use in automated processes and timed operations, the 88256506 can also be used to provide a safety shut-off. This can be used in industrial applications where an operation must be stopped after a certain amount of time in order to prevent injury or damage. By setting the timer to a certain delay, the relay will automatically shut off after a specified amount of time has elapsed.

In summary, the 88256506 Time Delay Relay is a versatile device that can be used in a variety of applications. Its adjustable timer allows for precise control of the timing of the relay operation, while its robust power supply ensures reliable operation in any environment. Whether it is used for a starter circuit, a lighting control system, or a safety shut-off, the 88256506 is a reliable and easy to use device.
