National Instruments NI-7932

The NI-7932 Controller for FlexRIO from National Instruments (Part Number: 783765-01) is engineered for high-performance applications requiring advanced input/output capabilities and fixed signal processing. This robust solution is equipped with a programmable Xilinx Kintex-7 K325T FPGA, which includes 50,950 slices and 840 DSP slices, along with 2 GB of onboard DRAM and support for SD cards up to 32 GB. The dual-core ARM Cortex A9 processor operates at speeds up to 667 MHz and comes with NI Linux Real-Time software for effective headless operation. Designed for field development, the NI-7932 has two SFP high-speed serial ports optimized for data streaming, ensuring reliable communication in demanding environments.

To ensure stable performance, the NI-7932 requires an external power supply ranging from 9 V to 30 V, with a connector that securely attaches via two screws; the maximum wire gauge for the power connector is 16 AWG. It delivers filtered and monitored power to I/O modules while providing synchronized data relay when the I/O sample clock is aligned with the controller's clocking circuitry. The internal reference clock features a VCXO oscillator with an accuracy of 5 ppm and operates at a frequency of 100 MHz, offering a frequency pull range of up to ±100 ppm. Moreover, the controller facilitates seamless clock synchronization through a bi-directional trigger line and the option to phase-lock to an external reference. With dimensions of 9.21 x 5.14 x 1.73 inches and a weight of 41.27 ounces, the NI-7932 exemplifies a compact yet powerful solution for sophisticated control and automation needs. A user manual and maintenance manual are available for download, and specifics on pricing can be obtained by contacting a sales representative. The product is backed by a 2-3 year warranty, ensuring reliable performance in industrial applications.
