Connection
Input En
Parameter
Output Q
Parameter
The on-delay time TH and the off-delay time TL 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 ＂ＴＨ＂，＂ＴＬ＂can be set/modified in parameter mode. For information about how to
modify, refer to chapter 5.2.2 please.
Description
The positive edge (0 to 1 transition) at the enable input En
(Enable) triggers the on delay for the random generator.
The negative edge (1 to 0 transition) triggers the off delay
for the random generator.
TH: The on delay is determined at random and lies
between 0 s and T .
H
TL: The off delay is determined at random and lies
between 0 s and T .
L
Q is set on expiration of the on delay if En is still set. It is
reset when the off delay time has expired and if En has not
been set again.
