The NI VXIpc-872B is a VXI slot 0 controller built around an Intel Pentium III (Mobile) processor running at 1.266 GHz with a 133 MHz system bus. It delivers computing power for data acquisition, instrument control, and VXI-based system management in industrial and scientific applications. The controller supports up to 512 MB of PC133 SDRAM plus 64 MB onboard memory, with dual SO-DIMM slots for field expansion. Storage options include configurable 3.5-inch bays for hard drive, floppy drive, and optional optical media. VXIbus Rev. 3.0 compliance ensures interoperability across standard VXI instrument racks.
