±63 V power conversion board

The DNA-PC-91x and DNR-PC-91x series provide external powerto various sensors and signal conditioning when required by yourapplication. The 91x series may also be used to provide power tothe various DNx series I/O boards requiring external power. The DNAversion is designed for use in UEI’s “Cube” chassis while the DNR seriesis for use in the RACKtangle chassis form factors. The DNx-PC-91x seriesis fully backward compatible with the DNx-PC-90x series boards.

The DNx-PC-910, 911, 912, 913 and 914 are designed to provideoutput voltages of ±10 VDC, ±15 VDC, +24 VDC ±45 VDC and ±63 VDCrespectively. Input power for the boards is provided by the internalCube or RACKtangle by default, but an external power supply* maybe used to power the units. The units are designed to automaticallydetect the presence of an external supply and use power from it whenavailable.

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

All connections are through a 37-pin D female connector. The pinout ofthis connector is identical to that of the earlier DNA-PC-90x series withthe exception that pins designated as “NC” on the 90x series are nowused as the connections to external power when used.

Software is included, providing a comprehensive, yet easy-to-useAPI 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 evenhigher level Windows driver—supplies complete support for thosecreating applications in many popular Windows programminglanguages, as well as data acquisition software packages such asLabVIEW and MATLAB/Simulink.
