026-1803 R13 Supervisor I&O User Guide 7 - 3
On the RS485 Network, the MultiFlex combination input/
output boards present themselves to site controllers as 16AI
Analog Input Boards, 8RO Relay Output Boards, 8DO Digital
Output Boards, and/or 4AO Analog Output Boards,
depending on what type of inputs or outputs are equipped.
Dip switches are used to assign network ID numbers to each
board type.
The MultiFlex combination input/output boards also
support a Hand-held Terminal interface, Section 7.2.8,Hand-
held Terminal (P/N 814-3110) which allows technicians to
view input values, check relay and analog output states, and
override output points with fixed digital or analog values. For
more information on MultiFlex I/O boards, refer to the
MultiFlex I/O Board Installation and Operation Manual (P/N
026-1704).
Table 7-2 shows the available models of MultiFlex
combination input/output boards with description and part
numbers.
7.2.2 MultiFlex CUB Support
The MultiFlex Condensing Unit Board (CUB) is a “smart”
input/output board designed to control single condensing
units. A single condensing unit is a self-contained
compressor and condenser bearing unit which controls
refrigeration in a single case line-up or walk-in cooler. The
MultiFlex CUB uses the same general hardware configuration
as a MultiFlex 168AO. It is equipped with a processor and
extra memory to allow it to control compressors, condensers,
refrigeration, and defrost for a single condensing unit using
on-board I/O and control algorithms. The MultiFlex CUB has
its own installation and operation manual, (P/N 026-1705).
7.2.3 MultiFlex RTU Support
This MultiFlex RTU (Rooftop Unit Board) support allows you
to set the inputs, outputs, setpoints and alarms on the user
interface, and transmit the data through I/O network between
RTU board and Site Supervisor.
