Technical data
7.4.2 control medium
In conjunction with pneumatic control units (positioner or process
controllers), pilot air according to DIN ISO 8573-1 must be used:
• Class 3 (for water content)
• Class 5 (for dust and oil content).
The specification is described in detail in the operating
instructions of the respective positioner / process controller
in the chapter entitled "Technical data".
