The positioner is used to adjust and control pneumatic actuators. The
controller operates electropneumatically with compressed air as an
energy supply.
The positioner together with the PROFIBUS PA communications inter-
face are components in a digital process automation system. It commu-
nicates with the master as a slave via the PROFIBUS PA field bus. The
field bus is used not only for communication but also to supply the posi-
tioner with electrical power.
For example, the positioner can be used to control valves as follows:
- with linear actuator (see M-figure 1-1, page 15) or
- with rotary actuator VDI/VDE 3845 (see M-figure 1-2, page 15)
Different mounting types are available for linear actuators:
- NAMUR or IEC534
- integrated mounting to ARCA
- integrated mounting to SAMSON
This means the positioner can be installed and operated on all common
actuator systems.
The positioner is available for double-acting and single-acting the
actuators and for applications in non hazardous areas.
The filter and connection module, the position feedback (pot) and the
valve block are integrated in the PS2 housing. The housing is made of
plastic or metal.
The PROFIBUS PA basic is integrated in the 19"-module rack with 5, 10
or 15 channels for SIPART PS2. The module rack is made of aluminum.
