Note 1:
Select either analog or switch output.
Note 2:
This characteristic is guaranteed within a regulation range between 10 and 90% of the full
scale, with a power voltage of 24V±10%, a supply pressure of 1 bar higher compared with
the set pressure (ex. regulation of 3 bar, supply pressure of 3+1 = 4 bar) and a volume
connected to the outlet without any loss. In applications with great air consumption, such
as the blowing, the indicated tolerance may change.
Note 3:
The above apply when working pressure
and control pressure are maximum.
Nota 4:
The above apply when working pressure is maximum
and the step is as follows:
50% F.S. -> 100% F.S.
50% F.S. -> 60% F.S.
50% F.S. -> 40% F.S.
