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
interface are components in a digital process automation system. It
communicates with the master 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 electrical power.
For example, the positioner can be used to control valves as follows:
with linear actuator (figure 1, page 15) or
S
with part--turn actuator VDI/VDE 3845 (figure 2, page 15)
S
Different mounting types are available for linear actuators:
NAMUR or IEC534
S
integrated mounting to ARCA
S
integrated mounting to SAMSON (non explosion proof version)
S
This means the positioner can be installed and operated on all common
actuator systems.
The positioner is available for the following actuators:
double--acting and
S
single--acting
S
For following applications:
potentially explosive or
S
not potentially explosive applications.
S
The electronics with display, position feedback and valve block are
integrated in the housing.
