Power Supply Output Boards

The DNA-PC-911-828 and DNR-PC-911-828 series provide external power to various sensors and signal conditioning when required by your application. The 91x series may also be used to provide power to the various DNx series I/O boards requiring external power. The DNA version is designed for use in UEI’s Cube chassis, while the DNR series is for use in the RACKtangle chassis form factors.

The DNx-PC-911-828 provides 28 VDC. (For other voltages, please refer to the DNx-PC-910, 911, 912 and 913, which are designed to provide output voltages of ±10 VDC, ±15 VDC, +24 VDC and ±45 VDC respectively). Input power for the boards is provided by the internal Cube or RACKtangle by default, but an external power supply* may be used to power the units. The units are designed to automatically detect the presence of an external supply and use power from it when available.

Outputs may be turned on and off under software control (default is On). The boards provide a read-back capability of the input voltage allowing the application to ensure acceptable input voltage levels.

All connections are through a 37-pin D female connetor. The pinout of this connector is identical to that of the earlier DNA-PC-90x series with the exception that pins designated as “NC” on the 90x series are now used as the connections to external power when used. All the DNx-PC-91x boards share the same pinout.

Software is included, providing a comprehensive, yet easy-to-use API that supports all popular operating systems, including Windows, Linux, and most real-time operating systems—such as QNX, Intime, VXworks, and more. Additionally, the UEIDAQ Framework—an even higher level Windows driver—supplies complete support for those creating applications in many popular Windows programming languages, as well as data acquisition software packages such as LabVIEW and MATLAB/Simulink.
