5.5.5 Wiping relay (pulse output)
Fashion: Classic:
Short description
An input signal generates an output signal of a configurable length.
Parameter
The off time T can be provided by the actual value of another already-programmed function:
Analog comparator: Ax – Ay
Analog trigger: Ax
Analog amplifier: Ax
Analog multiplexer: AQ
Analog ramp: AQ
Analog math: AQ
PI controller: AQ
Data latching relay: AQ
Up/Down counter: Cnt
The value of
＂ＴＬ＂
can be set/modified in parameter mode. For information about how to modify, refer
to chapter 5.2.2 please.

Description of the function
With the input signal Trg = 1, output Q is set to 1. The signal also triggers the time Ta, while the output
Connection Description
Input Trg You trigger the time for the wiping relay with a signal at
input Trg (Trigger)
Parameter T L represents the time after which the output is reset
(output signal transition 1 to 0).
Retentivity set (on) = the status is retentive in memory.
Output Q A pulse at Trg sets Q. The output stays set until the time T
has expired and if Trg = 1 for the duration of this time. A 1
to 0 transition at Trg prior to the expiration of T also resets
the output to 0.
