DNx-AI-217 – 16-Channel, 24-bit simultaneously sampling A/D board

16-Channel, 24-bit simultaneously sampling A/D board


The DNA-AI-217 and DNR-AI-217 are 16-channel simultaneously sampling A/D boards compatible with UEI’s popular Cube and RACKtangle chassis respectively.

The DNx-AI-217 is pin compatible with the popular DNx-AI-207 board and offers an easy upgrade path for those looking for more resolution, higher sample rates or simultaneously sampling inputs.



  • 16 differential analog input channels (+ one CJC channel)
  • Simultaneous sampling (one A/D converter per channel)
  • Direct Inputs for thermocouples (w/ DNA-STP-AI-U or DNA-STP-AI-207TC panel)
  • 120 kHz per channel sample rate (1600 kHz board max)
  • 24-bit resolution
  • “Open” input wiring detection
  • Input over-range detection
  • Gains – 1, 2, 4, 8, 16, 32 and 64
  • Pin compatible with DNx-AI-207

An A/D per channel configuration allows channels to be sampled simultaneously at rates up to 120 kS/s each (1600 kS/s max aggregate entire board). The A/D per channel configuration virtually eliminates input cross talk and channel settling time issues even when connected to high impedance signal sources.
The DNx-AI-217 is a member of UEI’s popular Guardian series, which provide high levels of user diagnostics. The AI-217 board provides both open input detection functionality as well as the ability to detect input overvoltage conditions.
oftware included with the DNx-AI-217 provides a comprehensive yet easy to use API that supports all popular operating systems including Windows, Linux, real-time operating systems such as QNX, INtime, VxWorks and more. Finally, the UEIDAQ Framework supplies complete support for those creating applications in Windows based data acquisition software packages such as LabVIEW, MATLAB/Simulink, or any application which supports ActiveX or OPC servers.
