PCI Model 76CS3

NAI’s 76CS3 is a PCI/PCIe Multifunction I/O and Communication Board designed for applications requiring Digital-to-Synchro/Resolver (D/S) and Digital-to-LVDT/RVDT (DLV) stimulus output, as well as I/O and communication functions. This full-slot board contains five independent, function module slots. The board can be configured for 6 separate D/S channels, or for D/S in combination with I/O and communication modules. Using multiple DSPs, the enhanced motherboard enables higher processing power and dedicated pre-processing control for each module.

By eliminating the need for multiple, specialized, single-function boards, this unique design increases packaging density, saves enclosure slots, and reduces power consumption. The 76CS3, a low-power/high-performance board, is ideally suited for rugged defense, commercial aerospace, and industrial applications.

Preexisting, fully-tested functions can be quickly and easily combined in an unlimited number of ways. Each I/O function has dedicated processing, unburdening the system Single Board Computer (SBC) from unnecessary data management overhead.
