                                            • GE IC695CHS012 RX3i Universal Backplane

                                              Overview

                                              IC695CHS012 is a 12-slot dual-bus universal backplane for GE PACSystems RX3i PLC control systems. It acts as the core rack carrier and internal communication backbone, compatible with multiple generations of GE control modules. It supports hot-swappable module replacement and mixed deployment of new PCI high-speed modules and legacy serial I/O boards, widely applied in industrial automation and power generation turbine control systems.

                                              Key Functions

                                              1. Centralized carrier platform
                                                  
                                                 Accommodates RX3i CPU, analog/digital I/O, communication modules and power supply modules, providing unified mechanical installation slots for the whole control system.
                                              2. Dual-bus signal transmission
                                                  
                                                 Transmits high-speed control data via PCI bus for new-generation IC695 modules; retains serial bus compatibility to reuse old Series 90-30 I/O cards, reducing system upgrade costs.
                                              3. Integrated power distribution
                                                  
                                                 Distributes converted stable internal power to all inserted modules from external 24VDC input through backplane traces.
                                              4. Hot-swap support
                                                  
                                                 Allows single module plug-and-replace without shutting down the entire rack, lowering equipment maintenance downtime.
                                              5. System expandability
                                                  
                                                 The dedicated expansion port connects serial expansion racks to expand total I/O capacity for large-scale control projects.
                                              6. Standardized grounding design
                                                  
                                                 Unified grounding bar suppresses electromagnetic interference and ensures stable signal transmission in industrial cabinets.
