Analog input board

Product Description

The DNx-AI-207 (DNA-AI-207, DNR-AI-207, DNF-AI-207) are analog input data acquisition boards for use in UEI’s Cube/RACKtangle/FLATRACK I/O chassis respectively. The DNx-AI-207 features 16 differential input channels with maximum sampling rate of 1kS/s per channel, wide range of gains, 18-bit resolution, and ±10V input range. Additionally, the DNx-AI-207 provides a dedicated CJC channel. The DNx-AI-207 is designed for mid- to low-speed high-resolution signal measurement. It represents an ideal solution for precise temperature measurement over a long period of time.

Another key feature of the DNx-AI-207 is the oversampling engine, allowing the board to automatically acquire as many samples as possible for the given gain/speed and average them, thus dramatically improving the noise floor.

Software included with the DNx-AI-207 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.
