IC695CHS012-CA: A 12-Slot Foundation for RX3i Uptime
Downtime on a PACSystems RX3i line rarely comes from the controller itself. It comes from the chassis that ties every module together. The IC695CHS012-CA is a 12-slot universal backplane built for that job, originally manufactured by GE Fanuc / GE Intelligent Platforms and now owned by Emerson. When a rack fails, the cost is not just the part — it is every hour the process sits idle.
What the Backplane Actually Delivers
The IC695CHS012-CA carries 12 standard slots, so one chassis can host a full mix of RX3i I/O, communications, and specialty modules. Fewer racks mean fewer power supplies, fewer interconnects, and lower cabinet cost per point. The dual bus — PCI and high-speed serial — lets modules communicate without an external bridge, which reduces both wiring labor and the number of failure points in the panel.
A serial expansion connector supports a remote backplane, so engineers can place I/O near the field devices instead of pulling long home runs back to the main cabinet. On large skids, that single feature can cut cable spend and installation hours significantly.

Cost Logic Behind the 12-Slot Layout
Every slot in the IC695CHS012-CA is a module you do not have to house elsewhere. Consolidating into one 12-slot rack lowers enclosure count, backplane count, and the labor hours tied to each additional chassis. For a plant running multiple RX3i lines, that is a repeatable saving on every panel build and every spare rack kept on the shelf.
The dual bus matters for the same reason. A shared PCI and high-speed serial path means less external hardware between modules, so commissioning is faster and troubleshooting is simpler. Fewer components translate directly into lower maintenance spend over the life of the rack.
Where This Backplane Fits
Oil and gas facilities often run RX3i racks in compressor control, pipeline monitoring, and water treatment skids. A 12-slot chassis gives room for analog inputs, discrete I/O, and communication modules in one enclosure — useful when cabinet space is tight and field wiring is expensive.
Industrial automation integrators also use the IC695CHS012-CA when building or rebuilding control panels. The remote backplane option supports distributed architectures, which is often the cheaper route when sensors sit far from the main control room.
Integration and Sourcing Notes
Because the IC695CHS012-CA uses a serial expansion connector, remote backplane layouts may require specific cabling or connection hardware. Confirm the exact cable and any gateway needs with your supplier before ordering, since these items are not part of the backplane itself.
Official Emerson production status for this model is unverified. It remains available through aftermarket channels as of the last verification in 2026-09. Please verify current lifecycle status and availability with Oil AutoTech before ordering.
