l Fuse-less short circuit protection
allows a short circuit to exist without blowing any fuses. When a particular
channel is shorted, internal circuits detect this and remove power to the

UIO-2
I/O
module/IOTA
Feature/function
In addition to all features supported by UIO, the UIO-2 supports the folowing
additional features:
l Provides one HART modem per I/O channel
l Supports pulse counting on up to four of any of the 32 channels
configured as DI
l Supports DO ganging within the following eight channel number groups: 1
- 4, 5 - 8, 9 - 12, 13 - 16, 17 - 20, 21 - 24, 25 - 28, and 29 – 32. However,
ganging across these groups is NOT possible
Beginning with ExperionR501, the following new features are available:
l Supports SOE on any channel
l Supports NAMUR inputs. This function, however, will require external
voltag
Series C I/O and C300/CN100 topology
ATTENTION
Topology for the Series C I/O and C300 - 20mS CEE Controller is similar to the Series C I/O
and C300 - 50ms Controller, with the exception that the C300 - 20mS CEE Controller does
not support the PMI/Os. CN100 supports all the Series C family of I/Os with the exception of
SPM and SVPM.
Series C I/O is attached to an IOLINK that is being mastered by a C300 controller. It is important to
note that:
l IOLINK - Serves as data repository for IOM function blocks in Control Builder to provide
communications interface with Series C I/O.
l Series C I/O cannot reside on an IOLINK mastered by an IOLIM or xPM.

Examining the topology rules
The following are the topology rules relating to the Series CI/O environment.
Refer to the following document for graphical representations of cabinet layouts depicting Series
C, PMIO, FIM, and LLMUX hardware configurations. Control Hardware Planning Guide
Item Impact Description
Redundancy None Redundancy capacity and performance is displayed while
redundancy is present.
Switchover Same as PM

Series C I/O hardware and/or software can switchover, recover,
and resume full view in a timeframe no greater than PM I/O.
Initialization All Series C I/O
