  • Permanently lubricated and maintenance free drive train
  • Capable of being mounted in any orientation
  • Accurate and repeatable position control
  • 4 to 20 mA loop powered, feedback signal
  • Digital communication options including HART®, Foundation Fieldbus®, Profibus®, Pakscan™, DeviceNet®, RIRO and Modbus® available
  • Wide standard ambient temperature range -22° to 158° F (-30° to 70º C)
  • Optional low temperature trim
  • Manual override standard
  • Electronic thrust/torque limiting
  • Two standard adjustable position switches
  • Field selectable adjustments for:
    • Deadband
    • Zero and span
    • Command signal type
    • Standard or reverse acting
    • Manual-auto operation
    • Output shaft position on loss of signal
