National Instruments PXI-7811

The National Instruments PXI-7811 is a digital reconfigurable I/O module designed to offer extensive customization and efficient processing capabilities for industrial automation and control applications. Featuring a client-programmable Virtex-5 FPGA, this module allows users to configure digital lines for multiple functions, including input/output, counter/clocks, PWM, encoder inputs, and custom communication protocols. It seamlessly integrates with LabVIEW FPGA, enhancing the development and deployment of applications requiring high-speed processing and reliability.

With advanced architecture, the Virtex-5 FPGA of the PXI-7811 delivers superior code execution and expanded capacity, optimizing resource usage thanks to its six-input lookup tables (LUTs) and DSP48 slices. This facilitates complex digital signal processing at faster rates, essential for applications such as rapid waveform generation, sensor emulation, hardware-in-the-loop (HIL) testing, and bit error rate testing, where precise timing and control are critical.

The PXI-7811 supports 160 digital I/O channels, providing robust versatility through its four 68-pin high-density VHDCI connectors. It operates under power requirements of +3.3 VDC and +5 VDC with a current draw of 650 mA and 9 mA, respectively. The module measures 6.3 inches by 3.9 inches and weighs 0.34 lb., making it a compact solution for space-constrained applications. It is compatible with the NI-RIO software driver and carries a warranty of 2 to 3 years. Although the PXI-7811 is classified as obsolete, it remains available for purchase and repair through Apex Waves.
