Separate Instrumentation
Amplifier & Input Stage
for Each Channel
One System Accepts up to 64 OMB-DBK17 Cards for a Total of 256
Simultaneously Sampled Inputs
产品描述
The OMB-DBK17 has been discontinued. Please contact our Data Acquisition
department for possible substitutes.
The OMB-DBK17 simultaneous
sample and hold card allows
OMEGA’s OMB-LOGBOOK and
OMB-DAQBOARD-2000 Series
data acquisition systems to capture
multiple input channels concurrently
in order to eliminate channel-to-channel
time skewing. Each
OMB-DBK17 provides four channels
of differential voltage input to an
OMB-LOGBOOK or
OMB-DAQBOARD-2000 Series.
The sixteen analog input channels
of the above data acquisition
systems can each accept four
OMB-DBK17 cards, for a total of
256 analog input channels with
simultaneous sampling. When
multiple OMB-DBK17 cards are in
use, all channels on all cards are
sampled at the same instant.
Each of the OMB-DBK17’s four
channels features an instrumentation
amplifier with switch-selectable
gains of x1, 10, 100, 200, and 500.
Each channel is also equipped with
a location for a user-selected gain
resistor, allowing you to select a
custom gain up to x500. Each of the
instrumentation amplifier input stages
is followed by separate sample-and-hold
stages whose outputs are
connected to an output multiplexer
stage. You can connect up to four
OMB-DBK17’s to one analog input
channel on an OMB-LOGBOOK or
OMB-DAQBOARD-2000 Series.
The OMB-DBK17 is equipped
with BNC input connectors. Its
differential inputs are equipped
with switchable 100 K bias resistors
referenced to analog common.
