2 Equipment Description
2.11 Serial Interface IOP (SI)
68 HPM High-Performance Process Manager Service R688
Honeywell December 2020
SI FTA installation
The Serial Interface FTA can be installed in the same cabinet as the Serial Interface IOP using model
MU-KLAMxx cable (the suffix “xx” designates the length of the cable in meters), or remotely, up to 305
meters (1000 feet) from the Power Adapter. The FTA is an A-size (6 inches) FTA and installs on a
standard FTA Mounting Channel.
FTA to Power Adapter interface
The Serial Interface FTA to Power Adapter connection is made using either model MU-KLAMxx cable
for internal cabinet installation or model MU-KLXxxx cable for external cabinet installation. The suffix
“xx” or “xxx” represents the length of the cable in meters.
The model MU-KLAMxx cable has two individually shielded, twisted pair wires. The shield must be
connected to ground at the Power Adapter end of the cable only.
The model MU-KLXxxx external cabinet cable has four wires with a single braided shield. The braided
shield must be connected at both the Power Adapter and FTA ends of the cable.
Cabling information
For more detailed information on cable selection, see the Process Manager I/O Installation manual or
the High-Performance Process Manager Planning manual.
