AME 655/655 GA Modulating & Three Point Control Actuator

Brand: Danfoss
Request Information
Favorite

Actuators are primarily designed to regulate valve in the respond to the demand of a controller in District Heating/cooling, Heating, Ventilating and Air conditioning systems. 

Actuators AME 655 can be controlled by electronic controllers with modulating or 3-point control output.
Features
  • Manual operation mechanical and/or electrical
  • Position indication, LED signalization
  • Selectable speed 2 or 6 s/mm
  • Automatic adaptation of stroke to valve's end positions that reduces commissioning time (self stroking)
  • Integrated auxilliary switch
  • Characteristic optimization
  • Adjustable stroke limitation
  • Anti-oscillation function
  • Pulse or continuous output signal (4 & 5)
  • Voltage or current output signal X
  • External reset button
  • Auto detection of Y signal
  • 3-point or modulating control selection
  • Galvanic insulation Y, X and output terminal 4 & 5
  • Thermal and overload protection
  • Precise control and fast response in 3-point mode (0.01 s)
  • Special feature for AME 655GA and AME 659SD:
    • Potential free terminal
    • Able to connect wires as were connect by AMV(E 41X or 61X)
    • Equipped with cable glands
