National Instruments 780691-04 PXI Embedded Controller

National Instruments 780691-04 is the part number for the PXI-8110 Embedded Controller with an extended range for temperature and a 32 Bit Windows 7 OS. This particular operating system uses less computing power than its 64-bit equivalent, which makes it a great option for embedded systems that are working with limited resources. The Intel Core 2 Quad processor features a 2.26 GHz clock speed, and the controller features a maximum 4 GB of single-channel DDR2 RAM. 

The extended operating temperature range of the 780691-04 is 0 to 55 °C ( 32 to 131 °F), while it’s increased storage temperature range measures -40 to 70 °C (-40 to 158 °F). Evaluated for compliance with IEC-60068-2-1 and IEC-60068-2-2 standards, these extended temperature ranges help the 780691-04 defend against the environmental uncertainties of industrial locations.  

The interoperability of the 780691-04 is on full display with the selection of external connectors featured on it’s front panel. Four Hi-Speed USB connections, a 24-Pin DSUB connection for video interface, a 9-Pin DSUB connection for serial interfaces, and a parallel port are just a few of the connector types that allow the controller to operate in a variety of configurations. 

Measured against a range of 5 to 500 Hz, the 780691-04 has gone under extensive testing for both shock and vibration. The operating shock has an 11 ms pulse, as well as a peak resistance of 30 g. When a solid-state hard disk is being used with the controller under operating conditions, it experiences random vibrations at a level of 0.3 grms. When the controller is under nonoperating conditions, this level rises to 2.4 grms.

The 780691-04 controller weighs an easily handled 0.914 kilogram (2.02 lb) and measures 8.1 cm by 13 cm by 21.6 cm (3.2 in. by 5.1 in. by 8.5 in.).
