Rotork CMA Range - CMR Multi-Turn Control Valve Actuator

Brand: Rotork PLC
CMA range modulating actuators deliver a series of sizes suitable for linear (CML), part-turn (CMQ) and multi-turn (CMR) control valve and pump applications requiring precise position control and continuous modulation.

The Rotork CMA Range provides for simple, safe and easy set-up via an internal electronic 6-segment LCD display and push button configuration.
Features
  • Can be powered by 1-phase or direct current supplies
  • Multi-turn drive action
  • Optional Local Controls with LCD Display (linear, part-turn, multi-turn) units available
  • 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™, RIRO, DeviceNet® 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
