Endress+Hauser Commubox FXA195 Technical Information
Technical Information
Commubox FXA195
Gateways / Interfaces
Intrinsically safe interface for Smart transmitters.
Converts HART protocols to USB signals.
Application
The Commubox FXA195 connects intrinsically safe
Smart transmitters with HART protocol to the USB port
of a personal computer. This makes the remote operation
of the transmitters possible with the aid of the
Endress+Hauser ToF Tool - Fieldtool Package, FieldCare
and ReadWin operating programs.
Power is supplied to the Commubox by means of the
USB port.
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.

Note!
The communication resistor (270 Ω) integrated in Commubox should not be connected in parallel to a power
supply point greater than 15 V. If the communication resistor is used, it should always be looped into the
4...20 mA circuit.
Note!
Prior to initially commissioning Commubox with the operating program (ToF Tool - Fieldtool Package,
FieldCare, ReadWin or Commuwin), the appropriate drivers must be installed from the CD-ROM supplied (list
of the Endress+Hauser operating programs and versions see Page 4).
