ICoT 6000 Series NEC Positioner

Brand: Westlock

Smart positioners for both spring-return and double-acting actuators on rotary and linear valves.

Available with HART, FOUNDATION Fieldbus and Profibus PA protocols.
Features
  • 3-button interface and graphical LCD for easy calibration and information display
  • Easy configuration of split range and reverse acting operation
  • Easy access to wiring terminal connectors
  • Non-contact valve position measurement via Hall effect sensor Eliminates the need for drive arms, linkages and increases overall resolution, accuracy and reliability
  • Advanced auto-calibration
  • Valve speed adjustable via user control
  • Available with optional dry contact limit switches
  • Optional 4-20 mA position feedback transmitter - HART version only
  • High-flow spool valve option for larger actuator/valves. Eliminates the need for volume boosters in some applications
  • Highly visible position indicator for rotary applications
  • Easily accommodates large stroke valves, such as knife gates
  • Fully compatible with AMS software and DTM
  • Rugged aluminum and stainless steel enclosures for maximum protection
