Special features

  • Electropneumatic positioner with HART® communication and pressure sensors
  • Die-cast aluminum or stainless steel housing
  • Attachment to linear actuators according to IEC 60534-6, VDI/VDE 3847, or SAMSON integral attachment
  • Attachment to rotary actuators according to VDI/VDE 3845
  • Attachment to double-acting actuators with Type 3710 Reversing Amplifier
  • Integrated EXPERTplus diagnostics for on/off valves in safety-instrumented systems
  • Certified according to IEC 61508/SIL
  • Pressure sensors to monitor the supply pressure and signal pressure
  • Any desired mounting position of the positioner (but not suspended)
  • Simple one-knob, menu-driven operation
  • Easy-to-read display in any mounting position thanks to rotatable reading direction
  • Configurable with a computer over the SSP interface using the TROVIS-VIEW software
  • Variable automatic start-up thanks to four different initialization modes
  • Preset parameters, only values deviating from the standard need to be adjusted
  • Calibrated travel sensor without gears susceptible to wear
  • Sub (substitution) initialization mode allows the positioner to be started up in case of emergency whilst the plant is running without having to change the valve position.
  • All parameters saved in non-volatile EEPROM
  • Two-wire system with small electrical load of 460 Ω
  • Adjustable output pressure limitation
  • Adjustable tight-closing function
  • Automatic zero monitoring
  • Integrated temperature sensor and operating hours counter
  • Two standard programmable position alarms
  • Self-diagnostics
  • Messages as condensed state conforming to NAMUR Recommendation NE 107, issued over a fault alarm contact or optional analog position transmitter
  • DTM file available for integration into FDT frame applications according to specification 1.2



  • Device compatible with paint
  • Additional equipment: inductive limit contact, solenoid valve, external position sensor, leakage sensor, binary input
