6.5 digit DMM board

The DNA/DNR/DNF-DMM-261 are 6.5 digit DMM (Digital MultiMeter) boards for use in UEI’s Cube/RACKtangle/FLATRACK I/O chassis respectively. Offering features and accuracy similar to standard “box” DMMs, the DNx-DMM-261 brings DMM functionality to UEI’s popular rugged, easily distributed chassis series. A unique capability of the board is its -40 °C to +85 °C operating range.

The board provides DC voltage input ranges from 300 VDC to 100 mVDC, AC voltage from 250 VAC to 125 mVAC, DC current ranges from 2A to 1mA, AC current ranges from 2A to 1 mA plus two and four wire resistance measurement ranges from 100 MΩ to 10 Ω. AC measurements are true RMS.

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 37-pin “D” connector, allowing OEM users to build custom cabling systems with standard, readily available components. The DNx-DMM-261 is also supported by a variety of switch boards that allow the DMM to easily interface to large, multichannel systems.

The DNx-DMM-261 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, yet 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, RTX, 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.
