Product Overview
The GE IC695ACC400CA is a universal backplane integral to Emerson’s PACSystems RX3i platform, originally developed by GE Intelligent Platforms. Designed for high-density industrial automation systems, this 7-slot backplane enables seamless integration of mixed I/O modules within a single chassis. Slot 0 is exclusively reserved for IC695 power supplies, while slots 1–5 support both PCI/serial interfaces for legacy GE Series 90-30 modules (IC693/IC694) and modern RX3i PCI modules. Slot 6 is PCI-only, dedicated to RX3i components. The GE IC695ACC400CA optimizes cabinet space in remote I/O architectures and features isolated 24VDC terminal blocks, integrated grounding bars, and clear slot numbering for error-free module installation. Its horizontal-mount design ensures optimal thermal management in IP20/NEMA Type 1 enclosures, making it ideal for substations, manufacturing cells, and process skids requiring hybrid legacy/new-system deployments.

Key Features and Advantages
Hybrid Slot Technology: Uniquely accommodates both PCI-based RX3i modules and serial-based 90-30 I/O in slots 1–5, enabling phased system upgrades without full hardware replacement. This reduces migration costs by up to 40% for brownfield installations.
Space-Efficient Design: With a compact footprint (264.9mm width), the backplane minimizes control cabinet volume while supporting up to seven modules. Integrated cable management via left-side terminal blocks simplifies wiring and maintenance.
Enhanced Reliability: Dual mechanical revisions (IC695CHS007-AA/BA) strengthen PCI connector durability. Horizontal-mount orientation prevents thermal throttling in confined spaces, critical for continuous processes like chemical dosing or power grid monitoring.
Application Areas
The GE IC695ACC400CA excels in hybrid industrial systems requiring legacy-to-modern transitions:
- Energy Management: Integrates 90-30 analog modules for substation voltage monitoring with RX3i safety controllers in grid protection systems.
- Water Treatment: Combines IC693 flow sensors and RX3i PACs for pump control in remote SCADA stations, leveraging corrosion-resistant terminals for high-humidity environments.
- Discrete Manufacturing: Enables mixed I/O configurations for robotic assembly lines, where Slot 6 hosts high-speed RX3i motion controllers while Slots 1–5 interface with legacy sensors.

Installation and Maintenance
Installation Prep: Mount IC695ACC400CA horizontally on DIN rails or panels using M4 screws. Verify 24VDC supply stability (±10%) before powering Slot 0 modules. Ensure 4-inch lateral clearance for convective cooling.
Maintenance: Clean air filters quarterly in dusty environments. Inspect PCI connectors annually for deformation; replace if insertion force exceeds 30N. Use GE’s Diagnostic Assistant software to monitor slot-level thermal metrics.
Product Assurance
All GE IC695ACC400CA backplanes include a 12-month warranty against manufacturing defects. Emerson provides lifetime technical support via global service centers, with advance replacement for critical failures within 72 hours. Firmware updates and legacy migration tools are accessible through Emerson’s PACSystems portal.
