Product - FasTrak Smart Positioner

​​​​​​​​​​Smart positioner with high-capacity, high-precision digital-pneumatic valve controller

FasTrak is a high-capacity, high-precision digital-pneumatic valve controller that replaces a conventional positioner. It has an excellent dynamic performance and high flow (Cv = 2). Configuration and calibration is carried out with a HARTTM device or by self calibration. FasTrak is compatible with double and single acting actuators, with or without a spring, a piston or a diaphragm.
 

 
​​​​

Key features​

  • High Flow Precision Control
    The unique design allows high speed performance in large volume actuators without additional amplification (e.g. booster or quick exhaust)

  • Control Algorithms & Hardware
    Self calibration on double acting piston, diaphragm, rotary actuator with or without spring; patented adjustable independent ​​control parameter to open and close stroke

  • Strong Shaft Design
    Not sensitive to radial and axial external load caused by mounting and linkages

  • Environmental Protection
    The IP66 protection and unique exhaust protection system makes it suitable to be installed in harsh environments where there is tropical rain, dust, sand, salt

    • 4-20 mA position feedback

    • Digital inputs for configurable trips

    • Digital outputs configurable for limit switches and/or alarm

  • Communications

    • 4-20 mA control and power with HART™ communication protocol

    • High speed serial connection

  • Sofware Interface
    Dedicated software (RCFT) to set, customize, control and monitor high dynamic performance

  • Certifications & Approvals

    • CE EUROPEAN DIRECTIVE

    • Intrinsically safe (Ex ia) / Explosion proof (Ex d [ia]) according to:


 

 







FasTrak is available in stainless steel 316 with explosion proof barrier




Benefits

  • No need for an amplification device in most applications

  • Superior control capacity of amplification device when installed

  • High flow with quick, precise complete control capability

  • Powerful self calibration software with the ability to totally personalise the parameters

  • Wide set of configurable embedded features

  • Robust design with a full metal housing
