Description
The Part Number 783763-01 identifies a specific model within the PXI FlexRIO Baseboards category, known as the NI-7931. This model is distinguished by its powerful processing capabilities, which include a Xilinx Kintex-7 325T FPGA and a Dual Core ARM Cortex-A9 processor. It is equipped with 512 MB of system memory, and it supports up to 2 GB of onboard DDR3 DRAM, providing ample capacity for demanding applications.
The NI-7931 features specialized clocking hardware, which includes a dedicated internal reference clock with a frequency of 100 MHz and a frequency pull range of +/-100 ppm, ensuring precise timing and synchronization. The Mounting Part Number 784365-01 is specified for this baseboard, indicating compatibility with certain mounting hardware. It is designed to withstand shock tolerances of more than 30 g/11 ms, with the caveat that certain considerations must be taken into account.
For installation, a minimum clearance of one inch on both sides of the board is required to ensure proper ventilation and operation. The NI-7931 also supports SD and SDHC standards for expandable memory, allowing for up to 32 GB of nonvolatile storage via an SD card. This flexibility is valuable for applications that require large datasets or logging capabilities.
Regarding power requirements, the board has a standby power consumption of 11.4 W and a maximum power supply capacity of 60 W. However, for optimal performance, a power supply of >75 W, 12 VDC is recommended. This ensures that the board has sufficient power for all functionalities, even under heavy load conditions.
