Vibration Sensor Interface Board Outfits Popular DAQ Module

For use with the PowerDNA Cube, the DNA-AI-211 analog-input board provides four isolated IEPE/ICP accelerometer/vibration sensor channels and offers 24-bit resolution with a 109 dB SNR. Configured with one ADC per channel, the board delivers sample rates up to 125 ksamples/s per channel, 500 ksamples/s total for the board. It supports direct connection to standard two-wire vibration sensors and provides both software and LED annunciation of open or shorted sensors. The board's 100-dB digital anti-aliasing filtering comes by way of a combination of analog and digital FIR filters. The digital filter enables a passband ripple of ±0.005 dB and a stop-band floor of -100 dB. The digital nature of the filter also ensures that each filter induces an identical phase shift, so no filter-induced inter-channel phase jitter will impact or corrupt subsequent analysis. Additionally, the board comes with a comprehensive software suite, which includes factory written support for popular operating systems, programming languages, and application packages such as LabVIEW, MATLAB, and DasyLAB.
