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 O

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.

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.
