The OMB-DBK18 low-pass filter card
provides OMEGA’s OMB-LOGBOOK
and OMB-DAQBOARD-2000 Series
data acquisition systems with four
low-pass filters that can be individually
configured for a cut-off frequency from
DC to 50 kHz, and for Butterworth,
Chebyshev or Bessel characteristics.
Each OMB-DBK18 provides four
channels of differential voltage
input to an OMB-LOGBOOK and
OMB-DAQBOARD-2000 Series.
The systems’ sixteen analog input
channels can each accept four
OMB-DBK18 cards, for a total of
256 analog input channels with
low-pass filtering.
Each of the OMB-DBK18’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 range of up to x500.
The OMB-DBK18’s frequency-determined
resistor and capacitor
locations are on machined-pin IC
sockets for maximum flexibility. The
card is provided with blank plug-in
headers for each channel, to which
you can add passive components for
particular frequencies.
The OMB-DBK18 is equipped with
BNC input connectors. Its differential
inputs are equipped with switchable
100 K bias resistors that are
referenced to analog common.
