Multifunction PCI DAQ. Model DT302-PBF. Multifunction Data Acquisition Boards
Each DT300 Series board contains 16 single-ended (SE) or 8 differential (DIFF) analog inputs, 23 digital I/O lines, and four counter/timer channels. The resolution and throughput of the analog input channels differ depending on the model. The DT302, DT304, and DT322 boards also provide 2 analog output channels. With the plug-and-play feature of the PCI bus, no jumpers or switches to set, and the common architecture, accessories, and software of the DT300 Series, installing and upgrading DT300 Series boards is easy.
Analog Inputs
All DT300 Series boards feature 16 SE or 8 DIFF inputs. In addition, an Amp Low connection allows SE inputs to be referenced to a common point other than ground to provide 16 pseudo-DIFF inputs. Software-selectable unipolar or bipolar operation and gain settings of 1, 2, 4 or 8 provide input ranges of 0-10 V, 0-5 V, 0-2.5 V, 0-1.25 V, ±10 V, ±5 V, ±2.5 V, and ±1.25 V. For added flexibility, a 1024-location channel-gain list allows you to sample non-sequential channels and channels with different gains. The A/D resolution and maximum sample rate vary depending on the board type, as listed below:
| Board | Resolution | Sample Rate |
| DT301/302 | 12-bit | 225 kS/s |
| DT303/304 | 12-bit | 400 kS/s |
By offering board types with different features, the DT300 Series provides the right cost-effective solution for your data acquisition needs. The analog input subsystem can be completely software calibrated for hands-off operation. Features:
- PCI bus mastering capability for analog inputs
- 16 single-ended or pseudo-differential analog input channels, or 8 differential analog input channels
- Signal conditioning through connections to 5B and 7B Series backplanes
- Input gains of 1, 2, 4 and 8
- Continuously-paced and triggered scan capability
- A 1024-location channel-gain list that supports sampling analog input channels at the same or different gains in sequential or random order
- Up to 256 scans per trigger for a total of 262,144 samples per trigger in triggered scan mode
- Internal and external clock sources for the analog input subsystem
- Digital TTL triggering for the analog input subsystem
- Software calibration of the analog I/O circuitry
- Two 8-bit digital ports programmable as inputs or ouputs on a per-port basis -digital input lines from these lines can be included as part of the analog input channel-gain list to the correlate the timing of analog and digital events; digital ouputs can drive external solid-state relays
- One 7-bit digital I/O port programmable as general-porpose (non-clocked) input or output port
