Timing Functions for Macromatic Time Delay Relays

Macromatic time delay relays are available as single function or multi-function units. The timing functions on these relays provide different modes of operation. Some are controlled just by the input voltage, while others also require the use of a trigger. Triggers include control switch or power triggers, and are implemented after the input voltage is already present.


Macromatic Time Delay Relay Timing Functions
Function Description Diagram
On Delay The time delay starts along with the input voltage. The output energizes after the time delay finishes. Taking out the input voltage resets the time delay and de-energizes the output.
Interval On The output energizes and the time delay starts along with the input voltage. After the time delay the output is de-energized. Taking out the input voltage resets the relay.
Off Delay The output energizes through the use of a trigger, and the time delay starts when the trigger is taken out. The output de-energizes after the time delay ends. Re-introducing the trigger while the time delay is going on will reset it and keep the output energized.
Single Shot The output energizes and the time delay starts through the use of a trigger. Re-applying the trigger during the time delay will not affect it. After the time delay the output de-energizes and needs another trigger to re-energize again.
Flasher OFF The time delay starts along with the input voltage. Once the time delay ends, the output energizes and stays energized for another time delay period. The cycle then repeats itself until the input voltage is taken out.
Flasher ON Works an opposite way compared to Flasher OFF. The time delay starts and the output energizes along with the input voltage. Once the time delay ends, the output de-energizes and stays that way for another time delay period. The cycle then repeats itself until the input voltage is taken out.
On/Off Delay Time delay (t1) starts through the use of a trigger, and the output energizes once t1 ends. The output stays energized after the trigger is removed for the duration of the time delay (t2). At the end of t2, the output de-energizes and needs another trigger to start the sequence again. Taking out the trigger during t1 keeps the output de-energized and resets the time delay (t1).
Single Shot Falling Edge Trigger is required to implement the timing sequence. Output stays de-energized when trigger is introduced and energizes when it is removed. This also starts the time delay. The output de-energizes after the time delay, and requires the trigger to be re-introduced and removed. Reapplying and removing the trigger before the time delay finishes keeps the output energized.
Watchdog Works in a similar way to Single Shot Falling Edge. The output energizes and the time delay starts through the use of a trigger. The output de-energizes after the time delay, and needs a trigger to restart the sequence again. Reapplying the trigger before the time delay finishes keeps the output energized.
Triggered On Delay The time delay starts along with the trigger. The output energizes when the time delay finishes and will stay that way until the trigger is removed. Taking out the trigger during the time delay keeps the output de-energized and resets the time delay.
Repeat Cycle OFF Time delay (t1) starts along with the input voltage. The output energizes after t1 ends and stays that way for time delay (t2). After t2 ends the sequence starts again until the input voltage is taken out.
Repeat Cycle ON Works in an opposite way compared to Repeat Cycle OFF. Time delay (t1) starts and the output energizes along with the input voltage. The output de-energizes after t1 ends and stays that way for time delay (t2). After t2 ends the sequence starts again until the input voltage is taken out.
Delayed Interval Time delay (t1) starts along with the input voltage. The output energizes after t1 finishes and stays energized for time delay (t2). After t2 ends the output de-energizes and the input voltage has to be taken out and re-introduced to restart the sequence.
Triggered Delayed Interval Time delay (t1) starts along with a trigger. The output energizes after t1 ends and remains energized for time delay (t2). After t2 finishes, the output de-energizes and the trigger needs to be re-introduced to restart the sequence. Removing and re-introducing the trigger during t1 and t2 has no effect on the output.
True Off Delay The output energizes along with the input voltage. The time delay starts after the input voltage is taken out and the output stays energized for the duration, after which it de-energizes. Re-introducing the input voltage during the time delay will reset it.
On Delay/True Off Delay Time delay (t1) starts along with the input voltage. The output energizes after t1 ends. If the input voltage is taken out, the output stays energized for time delay (t2), after which it de-energizes. Input voltage needs to be reapplied to start the sequence again. Re-introducing the input voltage during t2 keeps the output energized and resets the t2 time delay.
Single Shot Flasher Time delay (t1), time delay (t2), and the output energizes through the use of a trigger. The output stays energized for the duration of t2. After that the output de-energizes for t2, and the cycle repeats for the duration of t1. Removing the trigger and reapplying it during t1 will have no effect on the sequence.
On Delay Flasher Time delay (t1) starts along with the input voltage. The output energizes after t1 ends and stays that way for the duration of time delay (t2). It then de-energizes for another period of t2, and the cycle starts again, using the t2 time delay. The cycle keeps going until the input voltage is taken out.
