Description
The NI-7931 is an advanced computing module designed to meet the needs of demanding data processing and control applications. It is identified by its part number 783763-01 and is equipped with a powerful Xilinx Kintex-7 325T FPGA and a dual-core ARM Cortex-A9 processor. This combination offers exceptional performance for a wide range of applications.
The module features 512 MB of system memory, providing sufficient capacity for most control and processing tasks. Additionally, it includes up to 2 GB of DDR3 DRAM onboard memory, ensuring ample space for data storage and manipulation. This high level of memory support is crucial for applications requiring rapid access to large datasets or complex algorithms.
For precise timing and synchronization, the NI-7931 incorporates dedicated clocking hardware with a 100 MHz internal reference clock. This ensures accurate timing across all operations, a critical feature for systems requiring high precision. The frequency pull range of +/-100 ppm further enhances its timing capabilities, allowing for fine adjustments to meet specific application needs.
The device’s part number for mounting is 784365-01, and it boasts a remarkable shock tolerance of 30 g/11 ms when mounted upside-down. This robustness makes it ideal for use in environments subject to vibrations or sudden impacts. To ensure optimal performance and longevity, a minimum clearance of one inch on both sides is required for adequate ventilation.
SD card support is a flexible feature of the NI-7931, with compatibility for both SD and SDHC standards, allowing for up to 32 GB of expandable memory. This is particularly useful for applications that require additional storage for data logging, configuration files, or software updates.
In terms of power, the module has a standby power consumption of 11.4 W and can support a maximum power supply of 60 W. However, a recommended power supply of greater than 75 W, 12 VDC, is advised to ensure ample power for all
