The DNA/DNR-AO-308-020 are 16-bit, 8-channel current-output boards for use with UEI”s Cube/RACKtangle I/O chassis respectively. The boards provide per-channel digital offset and gain calibration, buffered output, excellent linearity, and low output noise. The DNA/ DNR-AO-308-020 features the industry standard 0-20mA output range. This layer may be used in variety of industrial data acquisition and control applications to interface with the sensors that comply with 0-20mA standard. Since the maximum power consumption exceeds 4.5W, this layer may require the rear-mount fan (DNA-FANx). Software is included, providing a comprehensive, yet easy-to-use API that supports all popular operating systems, including Windows, Linux, and most real-time operating systems—such as QNX, Intime, VXworks, and more. Additionally, the UEIDAQ Framework—an even higher level Windows driver—supplies complete support for those creating applications in many popular Windows programming languages, as well as data acquisition software packages such as LabVIEW and MATLAB/Simulink.
