AI LLMUX can be one to four Field Termination Assemblies.
Table 4.2 IOM types and ancillary hardware
These FTA's pre-condition and package the signals before they are received by the IOTA.
To simplify system hardware selection and to minimize spare parts requirements, IOMs can be
used with various types of IOTAs. The following table provides a list of IOMs, their associated IOTAs,
and ancillary hardware. All IOM models listed within the same cell can be installed on any of the
IOTAs listed in the adjacent cell.

ATTENTION
Connecting Series C IOM's into a Galvanically Isolated / Intrinsically Safe (GI/IS)
environment requires specific GI/IS IOTAs.
Refer to the following for GI/IS IOTAs and the IOMs they support: GI/IS IOTA models
