DNx-AI-212 – 12-Channel, fully isolated Thermocouple input board

• 12 fully differential analog input channels
• Channel-to-channel and channel-to-chassis isolation
• Simultaneous sampling (one A/D converter per channel)
• 24-bit resolution
• Built-in anti-aliasing filters
• Built-in 50, 60 and 400 Hz rejection
• 1800 Hz, per channel sample rates
• Built-in CJC circuitry for thermocouple monitoring
• Price includes screw terminal pins

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.

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.

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.
