DNx-AI-224 – 4-Channel High Speed Strain Gage Input Board


4-Channel High Speed Strain Gage Input Board

The DNx-AI-224 are high speed, four channel strain gage input boards for UEI’s data acquisition and control Cubes and RACKtangle I/O racks respectively. The boards provide an ideal combination of high speed, accuracy and connection flexibility and are suitable for use in a wide variety of applications.



  • For use with “Cube” chassis
  • 4 Strain Gage input channels
  • 18-bit resolution, 100 kilosample/second
  • Simultaneous sampling on all channels
  • Built-in anti-aliasing filters
  • Full, Half and Quarter Bridge inputs
  • 120, 350 and 1000 ohm bridge completion
  • Built-in tension/compression shunt calibration resistors

The analog inputs offer 18-bit resolution at sample rates up to 100 kilosamples per second. Each channel has an A/D converter and all four channels are sampled simultaneously. The combination of the 18-bit resolution with the board’s automatic offset zeroing and automatic gain calibration ensure the measurements are extremely accurate. Each channel also includes an anti-aliasing filter that automatically is configured to match the sample rate (*Please see the note on the following page for details)
The DNx-AI-224 offers 350 Vrms of isolation between the I/O connections and the Cube or RACKtangle. Like all UEI “Cube” and RACKtangle I/O boards, the DNA offers operation in harsh environments. Cube systems have been tested to 5g vibration, 50g shock, -40 to +85 ºC and altitudes up to 70,000 feet.
Software for the DNx-AI-224 is provided as part of the UEI Framework. The framework provides a comprehensive yet easy to use API that supports all popular Windows programming languages as well as supporting programmers using Linux and most real-time operating systems including QNX, INtime, RT Linux and more. Finally, the framework supplies complete support for those creating applications in LabVIEW, MATLAB/Simulink, or any application supporting ActiveX or OPC servers.
