IM-106-910Xi, Original Issue November 2010
Xi Advanced Electronics
3.The Xi can also transmit HART information wirelessly via a wireless THUM Adapter, Figure 1-4. The THUM Adapter threads into the Xi
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. Note that the THUM Adapter may also be used with the Oxymitter, mounted integral to the probe, or to the Oxymitter remote electronics.

Adapter
Optional OxyBalance Display and Averaging System
Receives up to eight 4-20 mA signals from individual Xi units. Trends individual outputs and calculates four programmable averages as additional 4-20 mA outputs. OxyBalance graphic displays are shown in Figure 1-5. See IM-106-4050, OxyBalance Oxygen Display and Averaging System, for additional details.
