Description

Smart performance with innovative and ever-strong coil module even under harsh working environments

Main features

  • Auto-calibration for optimum conditions
  • Precise control performance and high dynamic response
  • Easy operation with fork-key pads and full text graphical LCD
  • Single and double acting
  • Low air consumption due to piezo electric microvalve
  • Pressure regulator built-in to eliminate variations in supply air pressure
  • Problem-free characteristics on a small actuator
  • High resistance against shock and vibration
  • Mounting on rotary actuators according to VDI/VDE3845

Options

  • Output position transmitter (4 - 20 mA)
  • 2 x alarm limit or micro switch (SPDT)
  • By-pass (Auto/Manual switch)
  • Explosion proof type (Ex ia IIC T6)
  • HART communication
  • Profibus PA communication
  • Foundation FF communication
