Introduction
1.1 General information about the device
The SIPART PS2 positioner is used to position and control pneumatic
actuators. The instrument operates electropneumatically, compressed
air is used as the auxiliary power.
In the SIPART PS2 PA version, the positioner is used as a component
in a digital process automation system. It communicates with the mas-
ter as a slave via the PROFIBUS PS field bus. The field bus is used
not only for communication but also to supply the positioner with electri-
cal power.
The positioner can be used to control, for example values with
❑ a linear actuator (Fig. 1-3) or
❑ a rotary actuator VDI/VDE 3845 (Fig. 1-4).
Different ways of mounting are available for linear actuators
❑ NAMUR or IEC 534
❑ integrated mounting (ARCA, SAMSON)
so that the positioner can be mounted and used on all common types
of actuators.
The instrument is available for
❑ double-acting and
❑ single-acting
actuators, and for applications
❑ subject to explosion hazard or
❑ not subject to explosion hazard.
and the variants
❑ without PROFIBUS
❑ with PROFIBUS.
