The DNx-AI-212 are 12-channel fully isolated, simultaneously sampling thermocouple input boards compatible with UEI's popular Cube and RACKtangle chassis respectively. The DNA/DNR versions are electronically identical. The DNx-AI-212 features a ±2.048 V input range and 24-bit converters. At the gain of 16 used for most TC types the AI-212 provides an input resolution of 7.6 nanovolt.

An A/D per channel configuration allows simultaneous sampling at rates up to 1800 S/s each (21600 S/s aggregate). The A/D per channel configuration virtually eliminates input cross talk and channel settling time issues.

The DNx-AI-212 is an ideal, high accuracy thermocouple measurement device, offering offset and gain errors of less than 0.1°C on all standard thermocouples (including J, K, T, S, E, R). 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 thermocouples in high voltage environments.

Additionally, the DNx-AI-212 is designed to take advantage of the extremely accurate ADT 7420 digital temperature sensor which provides a dedicated CJC measurement. The CJC sensor is mounted externally on the DNA-STP-AI-212 screw terminal panel (which is included with the purchase). The software included will perform all required TC linearization and CJC compensation and return data in °C, K, °F or °R when desired. An open thermocouple detection circuit has also been implemented.

Software included with the DNx-AI-212 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. 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.
