Rosemount 6888Xi, Reference Manual, Page: 15 / 114

3. The 6888Xi can also transmit HART informa-
tion wirelessly via a wireless THUM Adapter,
Figure 1-5. The THUM Adapter threads into the
6888Xi conduit port and converts the 4-20 mA
O2 signal to a wireless protocol. All other HART
information is also transmitted.
In addition to the wireless THUM Adapter, a
hard-wire connection of the 4-20 mA signal to
the DCS may be used at the same time. More
detailed information regarding the application
of the THUM Adapter is available in Product
Data Sheet 00813-0100-4075.
4. The 6888Xi can be configured to communicate with a 6888A FOUNDATION Fieldbus probe.
Refer to section 3.2.1 Configuration to set up for FOUNDATION Fieldbus communications.
Optional OxyBalance Display and Averaging System
Receives up to eight 4-20 mA signals from individual 6888Xi units. Trends individual outputs and
calculates four programmable averages as additional 4-20 mA outputs. OxyBalance graphic dis-
plays are shown in Figure 1-5. See IM-106-4050, OxyBalance Oxygen Display and Averaging
System, for additional details.
