Concept
• 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)

Having fun!
Benefits of autostroke:
- automatic setting of control parameters
- independent parameters for open & close travel
- higher accuracy of adjustment
- no mechanical range adjustment
- suitable for all valve and actuator makes
Advantage:
=> Installation / Commissioning time saving
