Интерфейс передачи данных Commubox FXA195 USB/HART

The Commubox FXA195 is a intrinsically safe interface for Smart transmitters. It converts HART protocols to USB signals.

Your benefits:

  • Remote commissioning of field devices directly from the control room
  • Suitable for the ToF Tool - Fieldtool Package, FieldCare, ReadWin and Commuwin operating programs
  • For connection to intrinsically safe circuits (4...20 mA)
  • Reactionless in accordance with IEC 61508 for connection to 4...20 mA SIL 2 loops
