The OMB-DBK80 provides
16-channels of differential voltage
input for OMB-DAQBOARD-2000
Series and OMB-LOGBOOK
measurement systems. The
OMB-DBK80 can operate at the
full 100 KHz sample rate with no
degradation of published
performance.
The OMB-DBK80 has a single,
unity-gain input stage on all
channels. When coupled with the
on-board x1 through x64
programmable input gains on the
DAQBOARD-2000 Series and
OMB-LOGBOOK product lines, the
combination provides full-scale
input ranges from ±10V down to
±156mV full-scale inputs.
The OMB-DBK80’s ultra-low
noise design allows users to
expand their input channels up
to 256 channels, without incurring
additional noise or inaccuracies
due to the input expansion cards.
Up to 16 OMB-DBK80’s can be
attached to one A/D system, and
can also be combined with any
other OMB-DBK series expansion
and signal conditioning options.
The OMB-DBK80 also has a +5V
or +10V precision voltage source
on-board (jumper selectable).
This can also be used to bias
strain gages, thermistors, or other
transducers that require biasing.
