GE IC695CHS012-CA – 12-Slot Universal Backplane with Conformal Coating | PACSystems RX3i Platform
Engineering Background: The IC695CHS012-CA is GE Automation’s (formerly GE Fanuc) flagship 12-slot universal backplane for the PACSystems RX3i control platform. The “-CA” suffix designates the factory-applied conformal coating variant, engineered for deployment in harsh industrial environments where moisture, dust, chemical vapors, and thermal cycling would compromise standard PCB assemblies. This chassis serves as the physical and electrical backbone of an RX3i rack, hosting the CPU, power supply, and up to 12 I/O or specialty modules on a unified high-speed backplane bus.
Product Positioning: Designed for procurement engineers and system integrators who require a drop-in replacement or new-build chassis for GE PACSystems RX3i architectures. The IC695CHS012-CA is fully backward-compatible with IC695 and IC694 series modules, making it the preferred chassis for both greenfield installations and legacy system expansions in process control, discrete manufacturing, and critical infrastructure applications.

Engineering Advantages
- Dual-Bus Architecture: Simultaneous RX3i high-speed serial bus and legacy parallel bus allow mixed IC695/IC694 module populations in a single rack — protecting prior capital investment.
- Conformal Coating (-CA): Factory coating eliminates field-applied coating variability; ensures uniform coverage on all PCB surfaces, connectors excluded per design intent.
- Hot-Swap Ready: Supports module hot-insertion and removal (module-dependent) for zero-downtime maintenance in continuous process environments.
- Scalable Architecture: Expand via RX3i expansion chassis (IC695CHS016, IC695CHS007) using fiber-optic or copper expansion cables — no CPU change required.
- Deterministic Scan Times: Backplane bus arbitration ensures deterministic I/O scan performance critical for motion and process control loops.
- Long Product Lifecycle: GE/Emerson committed long-term support for PACSystems RX3i platform through 2030+, ensuring parts availability and firmware updates.
System Architecture & Signal Flow
In a PACSystems RX3i rack, the IC695CHS012-CA backplane routes power and communications as follows:
- Power Distribution: The dedicated power supply module (e.g., IC695PSA040) connects to the left-most power slot; the backplane distributes +5 VDC, +24 VDC, and isolated field power rails to all 12 module slots.
- CPU Communication: The CPU module (e.g., IC695CPE330) occupies slot 0 or 1 and communicates with all I/O modules via the high-speed RX3i serial backplane at up to 40 MB/s effective throughput.
- Legacy Module Integration: IC694-series modules inserted into any slot communicate via the parallel backplane bus; the CPU automatically detects and configures bus mode per slot.
- Expansion: An RX3i expansion module (IC695LRE001) in any slot connects downstream expansion racks via fiber or copper, extending the I/O domain without additional CPUs.

Technical FAQ
- Q: Can I use IC694 series modules in the IC695CHS012-CA?
- A: Yes. The IC695CHS012-CA supports both IC695 (RX3i serial bus) and IC694 (parallel bus) modules simultaneously. No adapter is required for IC694 modules in RX3i racks.
- Q: What is the difference between IC695CHS012 and IC695CHS012-CA?
- A: The “-CA” suffix indicates factory-applied conformal coating on the PCB assembly. Electrically and functionally identical; the -CA variant is specified for harsh environments per IPC-CC-830.
- Q: How many I/O modules can the IC695CHS012-CA support?
- A: Up to 12 modules in the main chassis slots. The power supply occupies a dedicated slot not counted in the 12. Additional I/O can be added via expansion racks.
- Q: Is the IC695CHS012-CA compatible with the IC695CPE330 CPU?
