• 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
