IDEC SmartRelay functions
IDEC SmartRelay Manual 140
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 Chapter 4.3.2.
The time for parameter T can be based on the process vari-
able of another, already programmed function. You can use
the process variables of the following functions:
• Analog comparator (actual value Ax - Ay, see Chapter
4.4.18)
• Analog trigger (actual value Ax, see Chapter 4.4.16)
• Analog amplifier (actual value Ax, see Chapter 4.4.20)
• Analog multiplexer (actual value AQ, see Chapter 4.4.26)
• Analog Ramp Control (actual value AQ, see Chapter
4.4.27)
• PI controller (actual value AQ, see Chapter 4.4.28)
and
• Counter (actual value Cnt, see Chapter 4.4.13).
Select the required function by means of the block number.
The timebase is configurable. For information on valid rang
-
es and parameter defaults, refer to Chapter 4.4.1.

Wiring Description
Input Trg A signal at input Trg (Trigger)
triggers the on-delay time.
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 Q Q is set after the time T has
expired.
