DNx-PC-911, DNA-PC-911, DNR-PC-911, DNF-PC-911

±15V power conversion board (layer) supplies power to external devices.

The DNx-PC-91x 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 DNx-PC-91x series is fully backward compatible with the DNx-PC-90x series boards.

The DNx-PC-911, 912 and 913 are designed to provide output voltages of ±15 VDC, +24 VDC and ±45 VDC respectively. Input power for the boards is provided by the internal Cube or RACKtangle by default, but and 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 also provide an output voltage read-back capability allowing the application to ensure acceptable output voltage levels.

All connections are through a 37-pin D female connector. 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.

The DNx-PC-91x power supply series includes software drivers supporting all popular operating systems including: Windows, Linux, QNX, VXWorks, INtime, and most other popular Real-Time Operating Systems. Windows users may take advantage of the powerful UEIDAQ Framework which provides a simple and complete software interface to all popular Windows programming language and data acquisition and control applications (e.g. LabVIEW, MATLAB).
