The National Instruments PCI-7811R is a Digital Reconfigurable I/O Device designed to provide high-performance embedded control solutions. Part of the R Series, this device features an integrated Virtex-II V1000 FPGA, enabling extensive configurability and optimizations tailored to specific I/O applications. The PCI-7811R supports 160 digital I/O channels and is equipped with four 68-pin Female High-Density VHDCI connectors, facilitating versatile wiring options through a dedicated connector intersection box. With advanced capabilities such as pulse width modulation (PWM) output for motor control, thermal management, and remote telemetry through pulse code modulation encoding, the PCI-7811R supports complex signal requirements seamlessly.

The FPGA’s architecture includes 10,240 flip-flops, 40 18 × 18 multipliers, and 720 kbits of embedded block RAM, allowing for sophisticated timing, triggering, and data processing tasks. Users can leverage the LabVIEW FPGA Module to program custom functionality directly onto the FPGA, enhancing the adaptability of the device for various applications. While the PCI-7811R has been announced as a mature status product by National Instruments, it continues to be available for purchase and repair through Apex Waves. The device operates on power requirements of +3.3 VDC and +5 VDC, with a consumption of 650 mA and 9 mA, respectively. Compact and lightweight, the PCI-7811R measures 6.7 inches by 4.3 inches and weighs only 0.25 lb. The device is supported by the NI-RIO software driver and comes with a warranty of 2-3 years.
