The Littelfuse TDR Series of time-delay relays are comprised of digital circuitry and an isolated, 10A relay output. The on and off delays are selected by means of two, ten position binary switches, which allow the setting of the desired delay to be precise every time.

Operation (Recycling - ON Time First)
Upon application of input voltage, the green LED glows, the output relay is energized, the red LED glows, and the T1 ON time begins. At the end of the ON time, the output deenergizes, the red LED turns OFF and the T2, OFF time begins. At the end of the OFF time, the output relay energizes and the cycle repeats as long as input voltage is applied.
Reset: Removing input voltage resets the output and time delays, and returns the sequence to the first delay.

Operation (Recycling - OFF Time First)
Upon application of input voltage, the green LED glows, the T1 OFF time begins, the load is OFF. At the end of the OFF time, the T2 ON time begins, the load energizes, and the red LED glows. At the end of the ON time the load de-energizes and the red LED turns OFF. The cycle repeats until input voltage is removed.
Reset: Removing input voltage resets the output and the sequence to the OFF time.

Features & Benefits:

ON & OFF time delay settings:   Independent adjustment allows for greater flexibility 

3 Time Ranges Available (0.1s to 2.8h):  Makes it versatile for use in many applications 

Microcontroller based:  Repeat Accuracy + / - 0.1% or 20 ms, whichever is greater; Setting Accuracy + / - 2% or 50 ms, whichever is greater

DIP switch adjustment:  Provides first time setting accuracy

Isolated output contacts Allows control of loads for AC or DC voltages 

LED indication (select models):  Provides visual indication of relay status

Littelfuse Automation Products

 

 


 

The Littelfuse TDM Series is a delay-on-make timer (TDR) that combines accurate digital circuitry with isolated, DPDT relay contacts in an industry standard 8-pin plug-in package. DIP switch adjustment allows precise selection of the time delay over the full time delay range. The Littelfuse TDM Series is the product of choice for custom control panel and OEM designers.


Operation (Delay-on-Make)
Upon application of input voltage, the time delay begins. The output is de-energized before and during the time delay. At the end of the time delay, the output relay energizes and remains energized until input voltage is removed.
Reset: Removing input voltage resets the time delay and output. 

 

Features & Benefits:

Wide delay range (0.1 s to 2.8 h):  User selectable via DIP switches for fine tuning to individual applications. 

Microcontroller based:  Repeat Accuracy + / - 0.1 % 

Dip switch adjustment:  Provides first time setting accuracy of +/- 2 % 

Setting accuracy +/- 2 %:  Provides flexibility for use in most applications 

LED indication Provides visual indication of time delay status 

Isolated 10 A, DPDT output contacts:  Allows control of loads for AC or DC voltages
