4.4.6 Edge-triggered interval time-delay 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.
Parameters TH and TL
Note the information on parameter T in topic Time response (Page 124).
The actual value of another already-programmed function can provide the pulse width TH and
the interpulse width TL. ou can use the actual values of the following functions:
Analog comparator (Page 183)(actual value Ax Ay)
Analog trigger (Page 178)(actual value Ax)
Analog amplifier (Page 191)(actual value Ax)
Analog multiplexer (Page 209)(actual value A)
Analog ramp control (Page 212)(actual value A)
Analog Math (Page 224)(actual value A)
PI controller (Page 216)(actual value A)
Up/down counter (Page 168)(actual value Cnt)
Analog filter (Page 229) (actual value A)
Average value (Page 235) (actual value A)
Max/Min (Page 231) (actual value A)
On-delay (Page 132) (current time Ta)
Off-delay (Page 136) (current time Ta)
On-/off-delay (Page 138) (current time Ta)
Retentive on-delay (Page 140) (current time Ta)
Interval time-delay relay/Pulse output (Page 142) (current time Ta)
Edge-triggered interval time-delay relay (Page 144) (current time Ta)

iring Description
Input Trg A signal at input Trg (Trigger) triggers the times for the
edge-triggered interval time-delay relay.
Input R A signal at input R resets the current time (T
a
) and the
output.
Parameter The interpulse width T
L
and the pulse width T
H
are
configurable.
N determines the number of pulse/pause cycles TL/
TH:
Range of values: 1...9
Retentivity:
/ No retentivity
R The status is retentive.
Output is set after TL expires, and reset after TH expires.
