[351] Differentiator (D-element)

Type

I3
I4 b Master Reset
Description:
The input value at I1 is differentiated.
The derivative action time indicates how long a linear ramp must rise until it has the same value
as the output of the differentiator.
O1 -O2 1 P
= = ×
If an integrator and a differentiator are connected in series, a p-element is obtained with ampli-
fication V = Td/Ti.
If, for example, the output value is limited in the case of a jump at the input, the limited value
will be output longer.
In the case of a jump at the input, the jump height/sampling time is assumed as the ramp gra-
dient.
As long as status TRUE is present at I4 (Master Reset), the output value O1 is 0.
Note:
Percentages [%] have two decimals.
For example: Value 12345

Description:
The absolute value of the input value at I1 is calculated. The output value at O1 is always posi-
tive.
