1.2. MultiFlex Combination In-
put/Output Boards
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
several new hardware options and software fea-
tures.
The MultiFlex combination I/O boards con-
sist of two circuit boards: a bottom layer with up
to 16 combination digital/analog inputs, and a
plug-in top layer which contains a combination
of relay outputs, digital outputs, and analog out-
puts.
All boards feature both +5VDC and
+12VDC output voltage points for use in power-
ing transducers or other input devices that
require power.
On the RS485 Network, the MultiFlex com-
bination input/output boards present themselves
to the Einstein or REFLECS site controller 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 inter-
face, which allows technicians to view input val-
ues, check output states, and override output
points with fixed digital or analog values.
Table 1-2 shows the available models of
MultiFlex combination input/output boards.
