Daqbooks & Daqboards; Using Dbk Cards & Modules For Signal Conditioning - Omega Engineering 100/200 Series User Manual

DaqBooks and DaqBoards
Daq products connect to one or more DBKs on their signal input side and a computer on their output side.
Each type of Daq device connects to the computer in a different way:
•
The DaqBook is an external module that connects to a computer's enhanced parallel port (EPP)
interface or PC-Card link.
•
The DaqBoard [ISA type] board is an internal card that plugs into an ISA-bus slot within a
computer.
Features common to the Daq products include:
•
100-kHz channel-to-channel scan and gain switching (10 µs);
200-kHz for DaqBoard/2000 Series and DaqBoard/2000c Series Boards.
•
512-location sequence memory that can be loaded with any combination of channels and gains.
•
Ability to access up to 256 different channels of DBK signals while maintaining the channel-to-
channel scan rate. The DBK expansion options can accommodate mixed-signal inputs from
thermocouples and RTDs to isolated high-voltage inputs and strain gages.
•
Ability to handle 8 differential or 16 single-ended signal inputs without DBK expansion units.
•
Ability to handle fixed digital I/O up to 4 TTL lines in and 4 TTL lines out (accessible only if no
analog expansion cards are in use).
The following table lists various features of DaqBooks and ISA-DaqBoards.

Using DBK Cards and Modules for Signal Conditioning
The DBK signal-conditioning cards and module are designed for use with DaqBooks, LogBooks, and
various types of data acquisition boards, i.e., ISA, PCI, and compact PCI (cPCI) 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.
