The National Instruments PXI-8155 is a high-performance embedded PXI controller designed to deliver optimal functionality and compatibility in industrial automation environments. Featuring a state-of-the-art PC-compatible design, the PXI-8155 incorporates essential built-in I/O components and includes onboard PCI video output, allowing seamless connectivity to the PXI bus without the need for a PCI-to-PCI bridge. This configuration effectively preserves the full 132 MB/s PCI bandwidth for additional PXI modules. The controller supports master functionality across all seven PXI slots, enabling users to install custom-designed peripheral devices in the remaining available slots.

For data storage, the PXI-8155 is equipped with a 1.44 MB floppy disk drive and a 2.5-inch hard drive with a capacity of 2 GB. Additional I/O options include one Super VGA port, one serial port, one IEEE 1284 parallel port, one USB connector, and a PS/2 interface for keyboard and mouse connection. With 16 MB of installed EDO DRAM and easily accessible memory sockets, the controller allows for straightforward memory upgrades, supporting a maximum RAM capability of up to 64 MB.

The PXI-8155 operates with a choice of 166 MHz or 233 MHz MMX processors, utilizing one system slot along with three controller expansion slots to facilitate system integration. Its PCI local bus architecture ensures a high-throughput capability of 132 MB/s, making it suitable for demanding applications. Although the PXI-8155 has been designated as obsolete, it remains available for purchase and repair through Apex Waves. Comprehensive user and maintenance manuals are accessible for download to ensure optimal usage and support. For pricing inquiries, please contact a sales representative. The PXI-8155 measures 3.2 x 5.1 x 8.5 inches and weighs 2.4 pounds, making it a compact yet powerful solution for PXI-based systems.
