With the 3 drops header cable and 6 drops drop cable, the I/O link can cover 3X3 rail-mounted UIO
modules as shown in this diagram.
ATTENTION
For more information about the I/O Link management, refer to the Experion Control
Hardware planning Guide.
8.4 Single Mode FOE for rail-mounted UIO
The Single Mode Fiber Optic I/O Link Extender (SMFOE) is used for the Rail-mounted UIO, as this
has a DIN rail-mountable option.
ATTENTION
FOE is mandatory for the installation and system wiring for Rail-mounted UIO.
FOE is placed inside the cabinet on the remote group side and also placed inside the cabinet on
the control room side.
l FOE Component Options: MOXA SMFOE option consists of the following parts.
o ICF-1150-S-SC-T, MOXA FOE Module, quantity - 2
o 51155436-100- Install kit, IOL Extender on DIN Rail, quantity -1
l The MOXA FOEs clip to a DIN rail and they are laterally secured by end brackets. Refer: DC
power line wiring through system tray in the section Wiring connections for illustration.
l Lower-left or right corner of the cabinet is ideal for mounting the FOE.
l One SMFOE is used for connecting to a matrix of 3X3 rail-mounted UIO network or lower. Refer
to the figures in the section System wiring for illustration.
l SMFOE can extend the I/O link up to 10 KM.
l Temperature specification of MOXA SMFOE is -40 to +85 degC.
l The “leap-frog” topology is supported for the SMFOE similar that of the Multi Mode. For more
information about the topology, see Defining the Fiber Optic topology.
