National Instruments PCI-7833R

The National Instruments PCI-7833R is a robust Digital Reconfigurable I/O Device designed for high-performance applications in industrial automation and control systems. It is built on the PCI architecture and features a powerful Xilinx Virtex-II FPGA with 3 million gates, offering comprehensive capabilities for custom logic design. The device is equipped with eight analog input and output channels, each capable of handling sampling rates of up to 200 kS/s and update rates of 1 MS/s, respectively. The PCI-7833R supports advanced functionalities such as digital communication protocols and inline signal processing, facilitated through the LabVIEW FPGA Module, which allows for easy graphical programming with minimal coding expertise.

For optimal signal conditioning and expansion options, the PCI-7833R can be combined with the NI-9151 expansion chassis. Furthermore, the device offers a ±10 V output range with enhanced R-2R DAC circuitry, achieving a current drive of ±2.5 mA and featuring user-configurable power-on states for both the analog outputs and 96 digital I/O channels, which are compatible with 3.3 V TTL and 5 V TTL logic levels. The device's connectivity is established through three 68-pin female high-density VHDCI I/O connectors. Operating under typical conditions, the PCI-7833R draws 727 mA from a +3.3 VDC power supply. Although the PCI-7833R has been marked as obsolete by National Instruments, it remains available for purchase and repair through acknowledged vendors such as Apex Waves. The device dimensions are 6.7 by 4.3 inches, and it weighs 112 grams.
