0BA2, 0BA3:
Only the parameter TH exists. TH represents the off-delay time for the output.
Input R is not available.
Short description
An input pulse generates a preset number of output pulses with a defined pulse/pause ratio (retriggerable), after a configured delay time has expired.
Connection | Description |
Input Trg | You trigger the times for the Edge-triggered wiping relay with a signal at input Trg (Trigger). |
Input R | The output and the current time Ta are reset to 0 with a signal at input R. |
Parameter | TH, TL: The pulse width TH and the interpulse width TL are adjustable. N determines the number of pulse/pause cycles TL / TH: |
Output Q | Output Q is set when the time TL has expired and is reset when TH has expired. |

Parameters TH and TL
The pulse width TH and the interpulse width TL can be provided by the actual value of another already-programmed function:
Analog comparator: Ax - Ay
Analog threshold trigger: Ax
Analog amplifier: Ax
Analog multiplexer: AQ
Analog ramp: AQ
Mathematic instruction: AQ
PI controller: AQ
Up/Down counter: Cnt
For the 0BA7 devices, you can additionally use the actual values of the following already-programmed functions:
On-delay: Ta
Off-delay: Ta
On-/off-delay: Ta
Retentive on-delay: Ta
Wiping relay(pulse output): Ta
Edge triggered wiping relay: Ta
Asynchronous pulse generator: Ta
Stairway light switch: Ta
Multiple function switch: Ta
Stopwatch: AQ
Analog filter: AQ
Average value: AQ
Max/Min: AQ
Thresholder trigger: Fre
You select the required function by the block number.
Timing diagram
Description of the function
With the change at input Trg to 1, the time TL (time low) is triggered. After the time TL has expired, output Q is set to 1 for the duration of the time TH (time high).
If input Trg is retriggered prior to the expiration of the preset time (TL + TH), the time Ta is reset and the pulse/pause period is restarted.
