DNx-AI-217-803 – Simultaneously Sampling A/D Board

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


The DNx-AI-217-803 are 8-channel fully isolated, simultaneously sampling A/D board compatible with UEI’s popular chassis The DNx-AI-217-803 feature 24-bit resolution, and 7 software selectable input ranges. Each channel also includes and isolated logic-level DIO bit.



  • 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)
  • 30 kHz per channel sample rate (480 kHz board max)
  • 24-bit resolution
  • “Open” input wiring detection
  • Input over-range detection
  • Gains – 1, 2, 4, 8, 16, 32 and 64
  • Allows low-pass FIR filter cut-off as low as 1 Hz

An A/D per channel configuration allows channels to be sampled simultaneously at rates up to 120 kS/s each (480 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.
Each channel is electrically isolated from all other channels as well as from the Cube or RACKtangle chassis. In addition to the isolation, each input is overvoltage protected up to ±40 V (power on or off). The inputs go into a high impedance mode when power is removed making the AI-217-803 ideal for use in redundant measurement/control applications.
Software included with the DNx-AI-217-803 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, VXworks and more.

Finally, the UEIDAQ Framework supplies complete support for those creating applications in data acquisition software packages such as LabVIEW, MATLAB/Simulink, or any application which supports ActiveX or OPC servers.
