The Auth 300 is designed to work with 4 to 20 m signal, profbus PA or Hart. Designed primarily for Damper boilers and ovens operations. The Auth 300 actuates the arm of the Dampers positioning according to the output signal of the controllers, providing a perfect answer for the tuning of meshes.

  • Compact and modular design;
  • Easy installation;
  • With integrated air filter;
  • Easy setting of parameters;
  • Time-tested and explosion-proof positioner;
  • Feature change with facilities;
  • Optional limit switch for pneumatic cylinder;
  • Ideal for Dampers actuation of boilers and ovens;
  • Robust for aggressive areas;
  • Stem Protection for Aggressive Environments.
