Macromatic TD-7 Series Time Ranger™ Digital-Set ProgrammableTime Delay Relays - Multi-Function

Macromatic TD-7 Series Time Ranger™ Digital-Set ProgrammableTime Delay Relays - Multi-Function (Plug-In)
   
The TD-781 Series offers an easy and accurate way to select a function & any time delay between 50ms & 999 hours. Programming is accomplished by using a pushbutton thumbwheel to select one of seven built-in time ranges and three pushbutton thumbwheels to digitally set the time delay required. This method provides a greater setting accuracy than is found on other units with an analog potentiometer. These units have a fifth pushbutton thumbwheel to select one of ten built-in functions. An LED indicates timing mode and time out condition. Macromatic TD-7 Series - Multi-Function
Features:
  • Ten user-selectable modes in one unit
  • Pushbutton Thumbwheels for digital set of time delay & function
  • 50ms - 999 hour programmable time range
  • Uses industry-standard 11 pin octal socket
  • 10A DPDT output contacts
  • LED indicates timing mode and time out conditions

Timing Functions
Code / Function Operation Timing Chart
(A) ON DELAY
Delay on Operate
Delay on Make
Upon application of input voltage, the time delay (t) begins. At the end of the time delay (t), the output is energized. Input voltage must be removed to reset the time delay relay & de-energize the output.. (A) ON DELAY
(B) INTERVAL ON
Interval
Upon application of input voltage, the output is energized and the time delay (t) begins. At the end of the time delay (t), the output is de-energized. Input voltage must be removed to reset the time delay relay. (B) INTERVAL ON
(C) OFF DELAY
Delay on Release
Delay on Break
Delay on De- Energization
Upon application of input voltage, the time delay relay is ready to accept a trigger. When the trigger is applied, the output is energized. Upon removal of the trigger, the time delay (t) begins. At the end of the time delay (t), the output is de-energized. Any application of the trigger during the time delay will reset the time delay (t) and the output remains energized. (C) OFF DELAY
(D) SINGLE SHOT
One Shot Momentary Interval
Upon application of input voltage, the time delay relay is ready to accept a trigger. When the trigger is applied, the output is energized and the time delay (t) begins. During the time delay (t), the trigger is ignored. At the end of the time delay (t), the output is de-energized and the time delay relay is ready to accept another trigger. (D) SINGLE SHOT
(E) FLASHER
(Off First)
Upon application of input voltage, the time delay (t) begins. At the end of the time delay (t), the output is energized and remains in that condition for the time delay (t). At the end of the time delay (t), the output is de-energized and the sequence repeats until input voltage is removed. (E) FLASHER - OFF 1ST
(F) FLASHER
(ON First)
Upon application of input voltage, the output is energized and the time delay (t) begins. At the end of the time delay (t), the output is de-energized and remains in that condition for the time delay (t). At the end of the time delay (t), the output is energized and the sequence repeats until input voltage is removed. (F) FLASHER - ON 1ST
(G) ON/OFF DELAY Upon application of input voltage, the time delay relay is ready to accept a trigger. When the trigger is applied, the time delay (t1) begins. At the end of the time delay (t1), the output is energized. When the trigger is removed, the output contacts remain energized for the time delay (t2). At the end of the time delay (t2), the output is de-energized & the time delay relay is ready to accept another trigger. If the trigger is removed during time delay period (t1), the output will remain de-energized and time delay (t1) will reset. If the trigger is removed during time delay period (t2), the output will remain energized and the time delay (t2) will reset. (G) ON/OFF DELAY
(H) SINGLE SHOT FALLING EDGE Upon application of input voltage, the time delay relay is ready to accept a trigger. When the trigger is applied, the output remains de-energized. Upon removal of the trigger, the output is energized and the time delay (t) begins. At the end of the time delay (t), the output is de-energized unless the trigger is removed and re-applied prior to time out (before time delay (t) elapses). Continuous cycling of the trigger at a rate faster than the time delay (t) will cause the output to remain energized indefinitely. (H) SINGLE SHOT FALLING EDGE
(J) WATCHDOG
Retriggerable Single Shot
Upon application of input voltage, the time delay relay is ready to accept a trigger. When the trigger is applied, the output is energized and the time delay (t) begins. At the end of the time delay (t), the output is de-energized unless the trigger is removed and re-applied prior to time out (before time delay (t) elapses). Continuous cycling of the trigger at a rate faster than the time delay (t) will cause the output to remain energized indefinitely. (J) WATCHDOG RETRIGGERABLE SINGLE SHOT
(K) TRIGGERED ON DELAY Upon application of input voltage, the time delay relay is ready to accept a trigger. When the trigger is applied, the time delay (t) begins. At the end of the time delay (t), the output is energized and remains in that condition as long as either the trigger is applied or the input voltage remains. If the trigger is removed during the time delay (t), the output remains de-energized & the time delay (t) is reset. (K) TRIGGERED ON DELAY
