The OMB-DBK18 low-pass filter cardprovides trodeks’s OMB-LOGBOOKand OMB-DAQBOARD-2000 Seriesdata acquisition systems with fourlow-pass filters that can be individuallyconfigured for a cut-off frequency fromDC to 50 kHz, and for Butterworth,Chebyshev or Bessel characteristics.Each OMB-DBK18 provides fourchannels of differential voltageinput to an OMB-LOGBOOK andOMB-DAQBOARD-2000 Series.The systems’ sixteen analog inputchannels can each accept fourOMB-DBK18 cards, for a total of256 analog input channels withlow-pass filtering.

Each of the OMB-DBK18’s fourchannels features an instrumentationamplifier with switch-selectablegains of x1, 10, 100, 200 and 500.Each channel is also equipped witha location for a user-selected gainresistor, allowing you to select acustom gain range of up to x500.The OMB-DBK18’s frequency-determinedresistor and capacitorlocations are on machined-pin ICsockets for maximum flexibility. Thecard is provided with blank plug-inheaders for each channel, to whichyou can add passive components forparticular frequencies.The OMB-DBK18 is equipped withBNC input connectors. Its differentialinputs are equipped with switchable100 K bias resistors that arereferenced to analog common.
