Using Dbk Cards And Modules For Signal Conditioning - Omega O-DAQSCAN-2000 Series User Manual

Using DBK Cards and Modules for Signal Conditioning

The DBK signal-conditioning cards and module are designed for use with DaqLabs, DaqScans,
DaqBooks, LogBooks, and various types of data acquisition boards, i.e., ISA, PCI, and
compact-PCI types. The DBKs perform best when used with an acquisition device that can
dynamically select channel, gain, and range. DBK cards and modules with dynamic channel
and gain/range selection allow for high channel-to-channel scan rates with a variety of
transducers.
Note: Only passive DBKs, such as the DBK1 BNC module, the DBK11A screw terminal card,
DBK output signals can be bipolar, e.g., -5 to +5 V, or unipolar, e.g., 0 to 10 V. The user can
select a range of relevant values to correspond to the lowest signal (e.g., -5 or 0 V) and the
highest signal (e.g., 5 or 10 V) signal. This type of range selection guarantees the highest
resolution in 12-bit or 16-bit conversion.
The majority of these modules have their own power supply; however, several options exist
for packaging and powering the DBKs.
