• Concept based on the reliable, successful predicessor- same functionality with Explosion proof enclosure

• Compact design and explosion proof- one-piece aluminium housing NEMA 4X / IP 65

• Adaptable to many applications- one device for linear and rotary actuators- one device for single and double acting actuators

• Fail safe options on loss of 4-20mA input signal- fail open or fail close (fail safe)- fail in-place (fail freeze)

• Advance AUTOSTROKE commisioning- all parameters are automatically optimized

• Easy to operate and configure- all setup functions are accessable in field while maintaining EXP

status• Communication / Configuration via HART Standard

- remote communication via FSK and Smart Vision software- remote communication with HHT275 / STT04 (from safe location

only)

• Optional modules (retrofitable)- analogue 4-20 mA position transmitter- digital valve position for Open / Close (min. & max.) - mechanical valve position for Open / Close (min. & max.)

• Mechanical Position indicator- large beacon indicator for valve position

• Smart (LCD) digital display for valve position and process information- valve position in % opening- setpoint deviation indication in % value- positioner temperature in deg F or deg C- actual input signal value in mA

• Position sensing via plastic film position sensor- reliable high resolution, low friction sensor

• Binary input and output available as standard- standard digital input for advanced override functions- standard digital output for diagnostic alarms

• Attractive price level- excellent price-performance-ratio

1. Local, via local pushbuttons => standard feature for USA => all functions accessable

2. via LCI-Interface at site=> standard feature => all functions accessable

3. via FSK-Module (HART-Protocol)=> standard feature => all functions accessable

4. via Handheld-Terminal => HHT 275 / STTO4

- easy to set up and configure either at siteor in the workshop

- easy to set up and configure from control room via 4...20 mA signal
