The positioner is used to adjust and control pneumatic actuators. The
controller operates electropneumatically with compressed air as an
energy supply.
For example, the positioner can be used to control valves as follows:
- with linear actuator (figure 1-1, page 13) or
- with rotary actuator VDI/VDE 3845 (figure 1-2, page 13)
Different mounting types are available for linear actuators:
- NAMUR or IEC 534
- integrated mounting to ARCA
- integrated mounting to SAMSON (non--explosion--proof version)
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
- single--acting
For following applications:
- potentially explosive or
- not potentially explosive applications.
The electronics with display, position feedback and valve block are
integrated in the housing.
The housing is available in three versions:
- Plastic housing for single and double--acting actuators
- Metal housing for single--acting actuators
- Explosion proof metal housing for single and double--acting
actuators
