DAQ24USB is a technically advanced 24-bit data logging system offering excellent performance at a low cost. DAQ24USB comes with a finished GUI application (shown below), Java and C libraries, programmable sensitivity, digital input/output, PC/104 form-factor, auxiliary 10-bit and temperature channels and USB connectivity.

  • USB interface. USB is the standard plug-and-play peripheral interface offering almost unlimited expansion and ease-of-use when compared to legacy parallel and serial ports.
  • Wide dynamic range. Four 24-bit analog channels with up to 130 dB of dynamic range and no missing codes. The DAQ24USB employs one delta-sigma analog-digital converter chip per channel for simultaneous sampling.
  • Low power. One-half watt power consumption .
  • Multi-platform. Drivers for Linux and Windows XP.
  • Java real-time display and control. DAQ-Sys-Lab displays incoming data and controls the digitizer (see below).
  • Digital I/O. Digital I/O is needed to synchronize and/or control external events and devices. Three input and three output lines are provided.
  • Unified data scan. Digital inputs are scanned along with analog data eliminating timing errors and ambiguities.
  • X1 - X64 amplification and voltage ranges. The on-board amplifier is software-controlled and eliminates the complication, power consumption and cabling associated with a separate amplifiers. Jumpers select between two voltage ranges.
  • PC/104. DAQ24USB conforms to the PC/104 form-factor and stack requirements.
  • Temperature sensor. On-board temperature data output.
  • DAQ24USB Standard Option. DAQ-Sys-Lab data acquisition program and libraries runs on a laptop or desktop PC. Data files can be imported into Excel, Matlab or any program able to read and ASCII file. The Java and C libraries enable developers to build their own applications.
  • DAQ24USB Network Option. DAQ24USB can up upgraded to the NetDAS data acquisition system offering full IP-network client/server support.
  • Auxiliary channels. Four 10-bit low data rate channels.
  • External power. Program-controlled and switched external 5 VDC power is available for external devices.
Photo shows DAQ24USB inside the shock-resistant industrial PC/104 enclosure. Window below is Java DAQ-Sys-Lab real time graphical display. Software buttons control centering and scale and individual channel statistics such as mean and standard deviation are presented. The other window controls gain, sampling rate, calibration and other parameters. Up to 16 DAQ24USB devices can be used at one time providing 64 channels 24-bit channels. The DAQ24USB is available as a printed circuit card for OEM applications or as a kit with enclosure, cabling and connection panel.
