Commubox FXA291 CDI/USB, intrinsically safe interface for intelligent level transmitters, converts HART protocol signals into USB signals
Advantages
-
On-site commissioning of Endress+Hauser devices
-
Simple connection of field devices to a computer USB port via the CDI interface
-
The Commubox is powered via the USB interface
-
The field device can also be powered via the CDI interface
-
Connects intrinsically safe and non-intrinsically safe field devices
-
Suitable for Endress+Hauser operating software such as FieldCare
-
CDI/USB drivers can be installed on Windows 2000, Windows XP and Windows 7 (x32+x64)
Field of application
The Commubox FXA291 is an intrinsically safe CDI interface (Endress+Hauser common data interface) for level transmitters that converts signals via the USB port. Field devices communicate with the computer via the CDI, the ToF adapter FXA291 or an adapter cable.
The Commubox FXA291 connects Endress+Hauser field devices to the USB port of a user computer or laptop via the CDI interface (Endress+Hauser common data interface). With Endress+Hauser operating software such as the plant-specific asset management system FieldCare, users can operate and service field devices remotely. USB low-power devices can be powered via the computer USB port.
