The National Instruments PCI-7831 is a multifunction reconfigurable I/O module designed for versatility in industrial automation applications. This module features a user-programmable FPGA based on the Virtex-II V1000 architecture, enabling users to create custom Virtual Instruments (VIs) that can operate in a Windows environment or on Real-Time (RT) software. With eight 16-bit analog inputs capable of sampling at 200 kS/s and eight 16-bit analog outputs at 1 MS/s, the PCI-7831 provides robust capabilities for data acquisition and control. Additionally, it offers 96 digital I/O channels, 10,240 flip-flops, and 40 18 × 18 multipliers, alongside 720 kbits of embedded Block RAM, making it suitable for complex processing tasks.

The PCI-7831 is compatible with the LabVIEW Real-Time Module, allowing seamless integration into real-time PXI systems, thus facilitating enhanced operational efficiency. For signal interfacing, NI provides a range of cables, including the SHC68-NT-S, which connects to the module’s VHDCI connectors, while the opposite end is non-terminated for customizable configurations. The device operates under measurement category 1 ratings, capturing signals at up to 200 MHz timebase frequencies. With dimensions of 6.7 inches by 4.3 inches and a weight of 0.25 pounds, the module is both compact and lightweight.

The PCI-7831 requires a power supply of +3.3 VDC and +5 VDC, drawing 462 mA and 330 mA respectively. It is equipped with the NI-RIO software driver, ensuring comprehensive software support. For further information, both user and maintenance manuals are available for download. For pricing details, please contact a National Instruments sales representative. The module is backed by a 2-3 year warranty, ensuring reliability and customer satisfaction.
