Rievtech x-Messenger Series - Edge Triggered Wiping Relay

229
Timing diagram
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
remains set.
When Ta reaches the value defined at T (Ta=T), the output Q is reset to 0 state (pulse output).
If the signal at input Trg changes from 1 to 0 before this time has expired, the output is immediately reset
from 1 to 0.
6.5.6 Edge triggered wiping relay
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.
Parameter
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
TL, TH: The interpulse period T
L
and the pulse period T
H
are
adjustable.
N determines the number of pulse/pause cycles T
L
/ T
H
:
Value range: 1...9.
Retentivity set (on) = the status is retentive in memory.
Output Q
Output Q is set when the time T
L
has expired and is reset
when T
H
has expired.
