National Instruments NI-7931

The National Instruments NI-7931 Controller for FlexRIO, part number 783763-01, is a high-performance embedded control solution designed to accommodate advanced signal processing and I/O capabilities. It features a Xilinx Kintex-7 325T FPGA with 50,950 slices and 840 DSP slices, along with a dual-core ARM Cortex-A9 processor and 512 MB of system memory. The controller supports onboard DDR3 DRAM, expandable up to 2 GB, and offers dedicated clocking hardware, providing a flexible clocking solution with an internal reference clock frequency of 100 MHz and a frequency pull range of ±100 ppm. Optimized for reliable and extended operation in demanding applications, the NI-7931 can be conveniently mounted using part number 784365-01, although care should be taken to support the FlexRIO Adapter Module when mounted in certain orientations. Adequate clearance of at least one inch on either side is required to maintain the desired ambient temperature. The controller supports SD and SDHC standards with expandable nonvolatile memory up to 32 GB via an SD card. Typical power consumption is 11.4 W, with a maximum supply requirement of 60 W; a recommended power supply of over 75 W is advised for optimal performance. The dimensions of the controller are 9.21 x 5.14 x 1.73 inches, and it weighs 41.27 oz. The NI-7931 is backed by a 2-3 year warranty, and both user and maintenance manuals are available for download.
