Rievtech x-Messenger Series - Wiping Relay (Pulse Output)

228
The current time Ta is triggered with a 0 to 1 signal transition at input Trg. Output Q is set to 1 when Ta
reaches the time T. A further pulse at input Trg does not affect Ta.
The output and the time Ta are only reset to 0 with a1 signal at input R.
If retentivity is not set, output Q and the expired time are reset after a power failure.
6.5.5 Wiping relay (pulse output)
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.
Connection
Description
Input Trg
You trigger the time for the wiping relay with a signal at
input Trg (Trigger)
Parameter
TL 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.
