Secure now IC695CHS012 GE Fanuc Universal Backplane
The IC695CHS012 is a state-of-the-art 12-Slot Universal Backplane engineered by GE Fanuc specifically for the PACSystems RX3i automation platform. Serving as the fundamental physical and electrical foundation of the control system, this baseplate is uniquely designed to support both the high-speed PCI bus (for advanced RX3i modules) and the legacy serial bus (for existing Series 90-30 modules). This dual-bus architecture provides unparalleled flexibility, allowing industrial facilities to seamlessly upgrade their processing capabilities without having to replace their entire I/O infrastructure. The 12-slot capacity ensures that even the most complex automation tasks, requiring numerous discrete, analog, and specialized communication modules, can be housed within a single, highly synchronized rack environment.

Expert Tips for Installation and Grounding
When installing the IC695CHS012 in a control cabinet, thermal management and grounding are your top priorities. The backplane must be mounted horizontally to ensure proper convective airflow across the installed modules. Never mount it vertically. Grounding is critically important for the PCI bus to function without data packet loss. The backplane features an exposed metal grounding bar running along the bottom; it is mandatory to connect this bar directly to the main enclosure’s earth ground using a thick, braided copper strap. Improper grounding is the leading cause of intermittent module failures and communication backplane faults in high-frequency electrical environments.
Maintenance and Expansion Strategies
The IC695CHS012 contains no active electronic components itself—it is a passive backplane—meaning its mean time between failures (MTBF) is exceptionally high. However, maintenance technicians should routinely inspect the physical slots for dust accumulation and airborne contaminants, which can settle on the pins and cause resistive connections. Always use blanking plates (slot covers) on any empty slots to prevent this. If you are integrating this system alongside remote I/O networks, you can explore adding VersaMax equipment such as the IC200PWR101 power supply and IC200MDL640 input module in your decentralized control panels.
Frequently Asked Questions (FAQs)
Q: Can the IC695CHS012 support Series 90-30 modules in all slots?
A: No. While it supports Series 90-30 I/O modules, the rightmost slot (Slot 11 in a 12-slot rack, excluding the power supply) often has restrictions depending on the specific CPU used. Always consult the RX3i compatibility matrix for slot limitations.
Q: Does this backplane require a specific power supply?
A: Yes, it requires an RX3i series power supply (such as the IC695PSA040), which must be installed in the dedicated leftmost slots, which do not count towards the 12 I/O slots.
