DNx-AI-222, DNA-AI-222, DNR-AI-222, DNF-AI-222

The DNx-AI-222 are 12-channel fully isolated, simultaneously sampling RTD input boards compatible with UEI's popular chassis. The DNx-AI-222 features 24-bit A/D converters with 50 μA excitation current for resistances up to 40 kΩ. At the gain of 16 used 100 Ohm RTDs the AI-222 provides an input resolution of better than 0.005 °C or 0.002 Ohm in the 0 - 312 Ω range.

An A/D per channel configuration allows simultaneous sampling at rates up to 150 S/s each (1800 S/s aggregate). The A/D per channel configuration virtually eliminates input cross talk and channel settling time issues.

The DNx-AI-222 is an ideal, high accuracy RTD measurement device, offering total errors of less than 0.2 °C on all standard 100 Ohm RTDs. This accuracy combined with the 350 VDC/Vrms channel-to-channel and channel-to-chassis isolation makes the board a perfect solution for industrial temperature measurement, even when using non-isolated RTDs in high voltage environments.

The software included will perform all required RTD linearization and compensation and returns data in °C, °K, °F or °R when desired. The software also allows the temperature conversion to be disabled and the inputs can measure resistance in Ohms up to 40 kOhms.

Software included with the DNx-AI-222 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, VXworks and more. 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.
