Description
The OE354 - 4 Analog Input/1 Analog
Output Modular Expansion Board is used
in conjunction with the OE352 - 2 Slot
Modular I/O Base Board or the OE353 - 4
Slot Modular I/O Base Board. The OE354
Expansion Board provides 4 analog in-
puts and 1 analog output.
For easy wiring the OE354 – 4 Analog
Input/1 Analog Output Modular Expansion
Board connects to the OE352 or OE353
Modular I/O Base Boards by means of an
integral connector arrangement. Power is
supplied to the OE354 - Expansion Board
through this connector, simplifying instal-
lation and connection. Jumpers are pro-
vided on the OE352 and OE353 Modular
I/O Base Boards for addressing of the
OE354 - Expansion Board(s).
The analog inputs have removable pull-
up resistors associated with each input,
which can be used for connection of
thermistor type sensors or dry contact
closure configuration. The pull-up resis-
tors are removed when a voltage signal is
to be used. Jumpers are provided to con-
figure the inputs for either 0-5 Volt or 0-10
Volt operation. Input and output resolution
is 0.4% or (0.04 Volts).
