Internal Design and Backplane Architecture

This expansion baseplate uses a passive backplane PCB for signal distribution. Ten slot connectors link each module to the internal expansion bus. The GE IC693CHS392E receives power and communication from the main CPU baseplate. A 50-pin expansion connector accepts a ribbon cable to the master rack. The passive design introduces no signal delay or active signal processing. Consequently, this baseplate supports high-speed communication between all installed modules.

Installation and Connection Guide

First, mount this baseplate into a standard 19-inch cabinet using four M6 screws. Next, install your power supply module into the leftmost slot of the baseplate. Then, insert I/O modules into the remaining slots as needed. Connect the 50-pin ribbon cable between this baseplate and the CPU baseplate. Use the shortest possible cable length for reliable communication (maximum 15 meters). Connect the M4 grounding stud to your system’s earth ground for safety. This expansion baseplate works with all Series 90-30 CPU models including 311, 331, 341, 363, and 364. Always terminate unused expansion connectors with the provided protective cover.
