iring Description
Input En A positive edge ( 0 to 1 transition) at input En (Enable)
triggers the on-delay time of the random generator.
A negative edge ( 1 to 0 transition) at input En
(Enable) triggers the off-delay time of the random
generator.
Parameter IDEC SmartRelay sets the on-delay at random to a
value between 0 s and T
The off-delay is set at random to a value between 0 s
and T
