Special features

  • Electropneumatic Ex d positioner with HART® communication
  • Die-cast aluminum or stainless steel housing
  • Attachment to linear actuators according to IEC 60534-6 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 control valves
  • Any desired mounting position of the positioner (but not suspended)
  • Simple one-knob, menu-driven operation also in hazardous areas
  • 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 between 300 and 350 Ω at 20 mA
  • Adjustable output pressure limitation
  • Adjustable tight-closing function
  • Automatic zero monitoring
  • Integrated temperature sensor and operating hours counter
  • Self-diagnostics
  • Messages as condensed state conforming to NAMUR Recommendation NE 107, issued over a fault alarm contact or optional analog position transmitter

Accessories

Options

  • Device compatible with paint
  • Additional equipment: position transmitter, binary input, forced venting function, binary output
