2.1.2.3 Intellegent Data Acquision I/O Board :: PCI/PXI-7831R Recongurable Multifunction
I/O Using the LabVIEW FPGA Module
Each solution uses the National Instruments PCI-7831R Recongurable FPGA. The FPGA is most useful
because it oers 8 analog inputs, 8 analog outputs, and 96 digital I/O lines making it scalable for both
teaching applications and research. The on board FPGA can be given a xed personality for student use,
or can be reprogrammed with the LabVIEW FPGA Module specically for your needs. PID control loop
rates up to 200,000 Hz. The 7831R also allows custom safety features to be implemented in the FPGA to
protect students and equipment. Because these safety features are implemented in hardware, they are not
dependent on the stability of the code running on the PC or real-time OS.
