The NI PXIe-8820 is a 3U PXI Express embedded controller that integrates standard PC I/O directly onto the chassis, freeing PXI slots for measurement and control modules. Built around an Intel Celeron 1020E dual-core processor running at 2.2 GHz with 2 MB L2 cache, it delivers up to 1 GB/s total system bandwidth with 250 MB/s per slot bandwidth. The controller ships with 2 GB DDR3 RAM (expandable to 8 GB) and a 250 GB SATA hard drive, providing the processing and storage capacity needed for data analysis and real-time control tasks in demanding industrial environments.
