4.4.4 Retentive on-delay
Short description
A one-shot at the input triggers a configurable on-delay time. The output is set when this time
has expired.
Parameter T
Note the defaults specified in topic Time response (Page 124).
The actual value of another already-programmed function can provide the time for parameter
T. 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 (current time Ta)

iring Description
Input Trg A signal at input Trg (Trigger) triggers the on-delay
timer.
Input R A signal at input R resets the on-delay time and the
output.
Parameter T represents the on-delay time for the output (output
status transition 0 to 1).
Retentivity:
/ no retentivity
R The status is retentive.
Output IDEC SmartRelay sets output after the time T
expires.
