3.2 Structure 
  SIPART PS2 with and without HART 
18  Operating Instructions, 10/2013, A5E00074631-11 
 
 
The following sections describe the mechanical and electrical structure, components, and 
principle functionality of the positioner. 
The positioner is available in the following configurations: 
●  SIPART PS2 without explosion protection in stainless steel, aluminum or Makrolon 
enclosure 
●  SIPART PS2 with Ex i protection in stainless steel, aluminum or Makrolon enclosure 
●  SIPART PS2 with Ex d protection in flameproof aluminum enclosure 
The positioner is used to move and control pneumatic actuators. The positioner works 
electropneumatically, using compressed air as auxiliary power. The positioner is used to 
control valves, for example, with: 
●  Linear actuator 
●  Part-turn actuator VDI/VDE 3845 
Various add-on extensions are available for linear actuators:  
●  IEC 60534-6-1 (NAMUR) 
●  Integrated addition to ARCA 
●  Integrated addition to SAMSON in non-flameproof aluminum enclosure
