I/O Network Boards and Peripherals Hardware Overview2-5
There are several models of the MultiFlex board that
combine the functionalities of input boards, relay output
boards, digital output boards, and analog output boards.
The MultiFlex combination input/output boards are
designed to be replacements for the 8IO Combination
Input/Output Board, but the MultiFlex board provides sev
-
eral new hardware options and software features.
The MultiFlex combination I/O boards consist of up
to 16
combination digital/analog inputs, and a combina-
tion of relay outputs, digital outputs, and analog outputs.
All boards feature both +5VDC and +12VDC output
vol
tage points for use in powering transducers or other
input devices that require power.
On the RS485 Network, the MultiFlex combination
inp
ut/output boards present themselves to Einstein, E2, or
REFLECS 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
suppo
rt a Hand-held Terminal interface, Section 2.2.4,
Hand-held Terminal (P/N 814-3110) which allows techni-
cians to view input values, check
relay and analog output
states, and override output points with fixed digital or ana-
log values. For more information on MultiFlex I/O boards,
ref
er to the MultiFlex I/O Board Installation and Opera-
tion Manual (P/N 026-1704).
Table 2-7 shows the available models of MultiFlex
combination input/output boards with description and part
