Introduction

SIPART PS2 Manual

A5E00074631-01

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
