Special features
- Electropneumatic Ex d positioner with HART® communication
- Certified according to IEC 61508/SIL
- Preset parameters for on/off valves in safety-instrumented systems
- Integrated EXPERTplus diagnostics with partial stroke testing (PST) function
- Optional fault alarm output for alarms generated by the EXPERTplus valve diagnostics
- Die-cast aluminum 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
- 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
- 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
- Pressure gauge
- TROVIS-VIEW Software (free of charge)
- Device integration files for engineering tools and systems
