The OME-DB-889D is an expansion
multiplexer/amplifier board for use
with OME-PCI-1800 series families.
Each OME-DB-889D multiplexes
16 differential analog input channels
into one analog input of the
DAS board. The high grade
instrumentation amplifier provides
software programmable gains of
0.5 , 1, 5, 10, 50, 100, 500 and 1000.
Thermocouple measurements
are handled easily with the
OME-DB-889D. The board includes
cold-junction sensing and
compensation circuitry that provides
a scaling of 24.4 mV/°C. Biasing
resistors are included for open
thermocouple detection. The
OME-DB-889D can be cascaded to
a total of 128 channels of voltage
measurements or 112 channels of
thermocouple measurement.
The OME-DB-889D has two 37-pin
D-sub connectors and two 20-pin
headers. One D-sub connector gets
connected to the A/D board’s
analog input connector while the
other D-sub connector can be
used to cascade to another
OME-DB-889D multiplexer.
The 20-pin header is the
multiplexer’s control logic circuit.
One of the 20-pin headers is
connected to the A/D board's
digital output port via 20-pin flat
cable. The other 20-pin header is
used to cascade to another
OME-DB-889D multiplexer.
