Product Introduction & Supply Chain Strategy
The GE Fanuc / Emerson IC695CRU320-BB is a high-availability PACSystems RX3i central processor designed for continuous process control applications. It executes complex logic programs with 64 MB of user memory while maintaining real-time data synchronization across redundant rack configurations to protect critical operations.
Securing this unit as New Surplus eliminates the reliability risks associated with aged capacitors and worn backplane connectors in secondhand parts. Maintaining an on-site New Surplus unit reduces Total Cost of Ownership (TCO) by providing immediate installation readiness, preventing unplanned downtime that can cost tens of thousands of dollars per hour.
Installation & Configuration Guide
Stage 1: Pre-Installation (Prep & Safety)
Execute full Lock-Out/Tag-Out (LOTO) protocols on the targeted rack power supply. Put on a grounded ESD wrist strap before opening static-shielded packaging or handling the module. Photograph the existing CPU DIP switch positions, port connections, and cable routing for exact replication.
Stage 2: Removal
Disconnect serial cables and fiber-optic redundancy links from the front panel. Press the top and bottom module release levers simultaneously to disengage the backplane lock. Slide the old CPU straight out from the RX3i Universal Backplane slot to prevent bending PCI backplane connector pins.
Stage 3: Installation (Clone & Seat)
Verify that the DIP switches on the IC695CRU320-BB mirror the original unit’s settings. Align the card edges with the backplane guide rails in slot 1 or 2 of the IC695 rack. Press the module inward until the top and bottom retention latches snap securely into place.
Stage 4: Power-On & Testing
Verify that 24 VDC power rails show stable voltage levels, then re-energize the rack. Observe the LED startup sequence: the PWR and OK indicators must show solid green. Establish a connection using Proficy Machine Edition, check diagnostic logs, and test failover readiness before returning the CPU to active control.
Firmware/Software Versions & Upgrade Notes
- Recommended Firmware: Revision -BB operates optimally on Firmware Revision 8.15 or higher using Proficy Machine Edition V8.60 or later.
- Redundancy Lock: Both primary and secondary CPUs in a redundant pair must run identical firmware versions. Mixing Firmware V7.XX and V8.XX prevents memory synchronization and disables automatic failover.
- Upgrade Caution: Never flash CPU firmware while the system is connected to an active production process. Flash the offline backup rack first, perform a manual takeover, and then update the secondary unit to prevent unmapped I/O dropouts.

Frequently Asked Questions (FAQ)
Why is this New Surplus unit priced higher than used alternatives on the market?
Our pricing reflects verified, factory-original inventory sourced from controlled distribution channels. Secondhand or repaired parts often suffer from thermal degradation, dry electrolytic capacitors, or worn backplane contacts that trigger intermittent faults. A New Surplus unit provides OEM-level operational lifespan with zero operational risk.
Is the IC695CRU320-BB completely new and unused?
Yes. This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability. Original packaging is opened solely for visual inspection and anti-counterfeit serial verification.
Can I hot-swap the IC695CRU320-BB in an active RX3i backplane?
No. While certain RX3i I/O modules support Insertion and Removal Under Power (RIUP), swapping the central CPU while the backplane is energized can cause bus disruption, fault trips, or physical damage to backplane contact pins. Always de-energize the rack before extraction or insertion.
Will the IC695CRU320-BB retain program memory during a power outage?
Yes. The IC695CRU320-BB utilizes non-volatile flash memory for logic and configuration storage. Battery backup maintains the real-time clock and volatile RAM tables, ensuring immediate system restoration upon power recovery.
How does this module fit into a critical spare parts inventory strategy?
For continuous process lines, the falls under the Class A Critical Spares category. Keeping 1 to 2 units on-site serves as an insurance policy against extended lead times, preventing catastrophic downtime in the event of primary hardware failure.
What warranty coverage comes with this New Surplus processor?
We back this unit with a full 1-year functional warranty. If any hardware defect or backplane communication error occurs under normal operating conditions within 12 months, we provide an immediate direct replacement from our inventory.
