Analog input boards for battery testing and aircraft power monitoring introduced by UEI

WALPOLE, Mass., 27 March 2013. United Electronic Industries (UEI) in Walpole, Mass., is introducing four analog input boards for high-voltage applications such as battery testing, power plant monitoring, and aircraft power monitoring.

All four of the boards offer eight analog input channels, 24-bit A/D resolution, and 120 kilosamples/second maximum sampling rates. The boards also offer, 350 Vrms channel-to-channel and channel-to-chassis isolation. The DNR versions are for use with the company's RACKtangle chassis, while the DNA versions are designed for installation into the PowerDNA Cube chassis.

The DNx-AI-218 offers a plus-or-minus 10 volts DC input range suitable for most general purpose DAQ measurements. The boards provide simultaneous sampling and each channel is based on its own oversampled SAR converter.

Input gains of 1, 2, 4, 8, 16, 32 and 64 are software programmable. A diagnostic input mode flags open circuited connections and overvoltage conditions. The boards also go into a high impedance mode when power is removed, making them suitable for high reliability, redundant monitoring applications.

Software included with the DNx-AI-218 and 228-300 provides an API that supports Windows programming languages. UEI also provides factory written drivers for all popular non-Windows operating systems including QNX, VxWorks, RTX, and InTime.

The UEIDAQ Framework supplies support for those creating applications in data acquisition software packages such as LabVIEW, MATLAB/Simulink, DASYLab or any application which supports ActiveX or OPC servers.
