3.6 Connecting IOMs and field devices through I/O
Termination Assemblies
IOTAs wiring diagrams
All connections between IOMs and field devices are through I/O Termination
Assemblies (IOTAs). IOTAs are sometimes connected to ancillary hardware that pre-
conditions the signal for use in Experion.
The following table defines the relationship between IOM type and the ancillary
hardware.
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.
