The National Instruments PXI-7830 is a robust Multifunction Reconfigurable I/O Device designed for advanced industrial applications. This unit features four independent analog inputs, each with a resolution of 16 bits and a maximum sampling rate of 200 kS/s. In addition to its analog capabilities, the PXI-7830 includes four autonomous analog outputs, also providing 16-bit resolution but with a higher maximum sample rate of 1 MS/s. The device is equipped with 56 bidirectional digital I/O lines that can be configured for various functions, including input, output, and counter/timer operations, facilitating flexible encoder inputs, custom communication protocols, and pulse-width modulation.

At the core of the PXI-7830 is a built-in Virtex-II V1000 FPGA, which allows for extensive programmability and on-device processing, enhancing the capability for real-time tasks. Users can leverage the LabVIEW FPGA module to customize digital and analog functionalities through graphical block diagrams, enabling efficient control over signal timing and synchronization. The design incorporates individual analogue-to-digital converters (ADCs) for each channel, providing independent triggering and multi-rate sampling—an advantageous feature that distinguishes it from standard data acquisition hardware.

Although the PXI-7830 has been announced as obsolete, it remains available for purchase and repair through Apex Waves. It is well-suited for applications in sensor simulation, rapid prototyping, custom control solutions, hardware-in-the-loop (HIL) testing, and digital protocol emulation. The device is supported by NI-RIO software drivers and comes with a warranty of 2-3 years, ensuring reliability in demanding environments. Detailed user and maintenance manuals are available for download to assist users in maximizing the capabilities of this multifunction device.
