The DNx-AI-248-230 (DNA-AI-248-230, DNR-AI-248-230, DNF-AI-248-230) are 24 channel differential analog input boards, for use in UEI's chassis. The high channel count allows a single six slot "Cube" to monitor up to 144 analog inputs in a single 4.0" by 4.1" by 5.8" package while the 12-slot RACKtangle chassis monitors up to 288 channels in a 3U rack.

The -2 to +32 Volt input range makes the AI-248-230 an ideal measurement solution in a host of automotive, aerospace and power generation applications where most DAQ product's 10 volts maximum input range cannot be used without external signal conditioning. Programmable gains of between 1 and 1000 combined with the board's 18-bit A/D converter provides resolution as low as 0.25 microvolt.

The DNx-AI-248-230 provides sample rates as high as 250 sample per second on each channel (6 k/s aggregate). Another great feature, the oversampling engine, allows DNx-AI-248-230 to automatically acquire as many samples as possible for the given gain/speed and average them, thus dramatically improving noise immunity.

One of the most powerful features of the DNx-AI-248-230 is automated offset compensation which can remove offset fluctuations over the temperature and/or time. This allows reduction of the temperature drift to a few microvolts over the full specified range.

The DNx-AI-248-230 offers 350 Vrms of isolation between itself and other I/O boards as well as between the I/O connections and the chassis. Like all UEI "Cube" compatible I/O boards, the DNA-AI-248 offers operation in extreme environments and has been tested to 5g vibration, 100g shock, from -40 to +85 ºC temperatures and at altitudes up to 70,000 feet.

The board is supported by a variety of cable and screw terminal options certain to meet the needs of almost all users. For those wishing to create their own cables, all connections are through a standard 62-pin "D" connector allowing OEM users to build custom cabling systems with standard, readily available components.

The DNx-AI-248 is supported by a complete software "suite" including support for Windows, Linux and all popular RTOS. Windows support is provided by the UEIDAQ Framework which includes a simple and complete software interface to all popular Windows programming languages and DAQ applications including LabVIEW and MATLAB. An extensive factory written software suite is also provided for all popular "non-Windows" operating systems including Linux, VXworks, QNX, INtime and more. All software support includes extensive example programs that make it easy to cut-and-paste the I/O software into your applications.
