OME-CA-2010 10 20-pin flat cable, 1 m (3')
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.
