4-channel IEPE/ICP® Vibration Sensor Interface Board for UEI’s PowerDNA Cube

The board features four fully isolated, IEPE/ICP® accelerometer / vibration sensor channels and offers 24-bit resolution with a 109 dB signal to noise (S/N) ratio. Configured with an A/D per channel, the board offers sample rates up to 125 kS/s per channel (500 kS/s for the board). The AI-211 is specifically designed to allow direct connection to industry-standard 2-wire vibration sensors and provides both software and LED annunciation of open or shorted sensors.

The AI-211's 100dB digital anti-aliasing filtering is provided by a combination of analogue and digital FIR filters. The digital filter allows a combination of low passband ripple (±0.005 dB), steep falloff and low stop band floor (-100 dB) unattainable with simple analogue filtering. 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.

The DNx-AI-211 is fully supported by UEI’s comprehensive software suite, which includes factory written support for all popular operating systems (eg Windows, Linux, VxWorks), programming languages (eg C, C# and VB .NET) and application packages such as LabVIEW, MATLAB and DasyLAB SyntaxError.

The DNA-AI-211 sets a new standard in the ICP/IEPE interface market according to UEI President Shaun Miller. In addition to the exceptional performance of the new board no other vendor offers the flexibility of UEI’s Cube and RACKtangle form factors and Ethernet Slave, Data Logger, Programmable Automation Controller or Simulink target deployment options.

About the Cube

UEI's powerful ‘Cube’ architecture is a compact (4 x 4 x 4 or 4 x 4 x 5.8) Ethernet based I/O platform. It may be deployed in four different configurations:

1. Ethernet I/O systems slaved to a host PC
2. Standalone Data Logger/Recorder
3. Linux-based Programmable Automation Controller (PAC) or
4. Modbus TCP-based I/O slave.

Each Cube consists of a core module (for the processor and network interface) and three or six open I/O slots. Users select the option that meets their needs and then match the I/O configuration of the ‘Cube’ to their application by selecting appropriate I/O boards. With over 30 I/O board types available, there's sure to be a configuration to meet almost any application requirement. The six slot ‘Cube’ provides up to 150 analogue inputs, 192 analogue outputs, 288 digital I/O, 48 counter or quadrature channels, 72 ARINC-429 channels and/or 24 Serial or CAN-bus ports. A full description of ‘Cube’ is available at http://ueidaq.adeptscience.co.uk.

About the RACKtangle

The DNR-12-1G RACKtangle chassis is a compact, rugged Ethernet-based data acquisition and control I/O rack. It provides two independent Gigabit Ethernet interfaces and front-access slots for up to 12 I/O boards, a design that dramatically increases performance and simplifies system reconfiguration and service. The RACKtangle is an ideal substitute for VME technology in data acquisition and control applications. It is also an ideal choice for Ethernet data acquisition and control applications where a small footprint, high density and high performance are desired.
