IC695ACC403 Lithium Battery Module (Industrial-Grade Memory Protection)

The IC695ACC403 is a compact lithium battery module engineered to safeguard program logic and configuration data in GE Fanuc RX3i PACSystems controllers. When primary power fails, this rackless energy pack automatically activates to preserve volatile memory contents for up to 30 days, eliminating costly downtime and preventing data corruption in mission-critical automation systems.

Designed for industrial environments where controller reliability is non-negotiable, the IC695ACC403 combines hot-swap capability with visual health monitoring, enabling proactive maintenance without system interruption. Its space-saving rackless architecture integrates directly with RX3i CPUs, delivering enterprise-grade backup protection without consuming valuable rack real estate.

Whether you're managing continuous process control, discrete manufacturing, or infrastructure automation, the IC695ACC403 provides the insurance policy your operations demand—protecting years of programming investment and operational data from unexpected power events.

Core Features & Benefits

✓ Extended Memory Retention
Maintains program files, data tables, and system configurations for 30+ days during complete power loss, far exceeding capacitor-based backup solutions that offer only minutes of protection.

✓ Zero-Downtime Replacement
Hot-swappable design allows battery replacement during live operation—simply disconnect the depleted module and install a fresh unit within 30 seconds while the controller remains powered and operational.

✓ Intelligent Health Monitoring
Integrated LED indicator provides real-time battery status feedback (green = healthy, amber = replace soon, red = critical), enabling predictive maintenance scheduling before failures occur.

✓ Compact Rackless Installation
Mounts directly to the RX3i CPU module without occupying rack slots, preserving expansion capacity for I/O modules, communication interfaces, and specialty cards.

✓ Industrial Temperature Tolerance
Operates reliably across 0°C to 60°C ambient conditions, with storage ratings from -40°C to 85°C for extreme climate installations and transportation scenarios.

✓ Compliance-Ready Design
UL, CE, and RoHS certified for global deployment, meeting safety and environmental regulations in North America, Europe, and Asia-Pacific markets.

Typical Application Scenarios

→ Pharmaceutical Manufacturing
In batch processing systems, the IC695ACC403 protects validated recipes and FDA-compliant audit trails. When utility power fluctuates during storm events, production formulas remain intact, preventing costly batch rejections and regulatory documentation gaps.

→ Wastewater Treatment Plants
SCADA controllers managing pump sequencing and chemical dosing rely on the IC695ACC403 to preserve PID loop tuning and alarm setpoints. During grid outages, operators can restore power without reconfiguring complex treatment algorithms.

→ Automotive Assembly Lines
Robot coordination programs and quality inspection parameters stored in RX3i controllers are safeguarded by the IC695ACC403. Unexpected power interruptions don't erase weeks of production optimization work or force line recalibration.

→ Data Center Infrastructure
Building management systems controlling precision HVAC and access control depend on the IC695ACC403 to maintain zone schedules and security credentials during UPS battery swaps or generator transfer events.

→ Remote Pipeline Monitoring
In oil and gas applications where controllers operate in unmanned field stations, the IC695ACC403 ensures flow computer data and safety interlock logic survive solar power system failures or lightning-induced outages.

Technical Parameters & Selection Guide

Selection Criteria: Choose the IC695ACC403 when your RX3i application requires memory retention beyond 48 hours. For shorter backup needs (under 24 hours), capacitor-based solutions may suffice. For Series 90-30 legacy systems, specify the IC693ACC302 instead. Always verify battery installation date and plan replacement every 5 years regardless of LED status to ensure maximum reliability.

Extended Functions

Predictive Maintenance Integration
The IC695ACC403's LED status can be monitored via RX3i diagnostic registers, enabling integration with SCADA alarm systems or IoT platforms. Configure email alerts when battery health degrades to amber status, allowing maintenance teams to schedule replacements during planned downtime windows rather than emergency callouts.

Multi-Controller Standardization
For facilities deploying multiple RX3i controllers, the IC695ACC403 provides a universal backup solution across CPU models from the IC695CPU310 entry-level processor to the IC695CPE400 high-performance controller. This standardization simplifies spare parts inventory and technician training requirements.

Environmental Monitoring Compatibility
When paired with temperature-monitoring I/O modules, the IC695ACC403's performance can be correlated with ambient conditions. In extreme heat environments (above 50°C), battery life may decrease to 3-4 years—data logging enables evidence-based replacement scheduling.

Delivery & Service Assurance

Documentation Package: Each IC695ACC403 ships with installation quick-start guide, safety data sheet (SDS), and certificate of conformity. Full technical manuals and CAD drawings available for download from our support portal.

Frequently Asked Questions

How do I know when the IC695ACC403 battery needs replacement?
The integrated LED indicator transitions from green (healthy) to amber (replace within 30 days) to red (critical—replace immediately). Additionally, RX3i controllers log battery status faults in the diagnostic buffer, which can trigger SCADA alarms for proactive notification.

Can the IC695ACC403 be used with redundant RX3i CPU configurations?
Yes, redundant RX3i systems require one IC695ACC403 per CPU module. Each controller maintains its own memory backup independently. During hot-standby switchover events, both batteries ensure seamless program retention regardless of which CPU is active.

What is the maximum time I can leave an RX3i controller unpowered with the IC695ACC403 installed?
Under ideal conditions (25°C storage temperature, fresh battery), the IC695ACC403 provides 30+ days of memory retention. However, for long-term storage (over 60 days), we recommend uploading programs to external storage and performing a fresh download upon recommissioning.

Does the IC695ACC403 require periodic testing or maintenance?
No active maintenance is required beyond visual LED inspection during routine site visits. Unlike rechargeable battery systems, the IC695ACC403 lithium cell does not require discharge/recharge cycling. Simply replace the entire module when the LED indicates end-of-life.

Is the IC695ACC403 compatible with older IC695CPU310 controllers from 2010?
Yes, the IC695ACC403 is backward compatible with all RX3i CPU models manufactured since the platform's introduction in 2003. The battery connector interface has remained standardized across all RX3i generations, ensuring long-term parts availability.

Can I ship equipment internationally with the IC695ACC403 battery installed?
Lithium batteries are subject to IATA dangerous goods regulations for air transport. For international shipments, we recommend removing the IC695ACC403 and shipping it separately in compliance packaging, or using ground/ocean freight where lithium battery restrictions are less stringent. Consult your logistics provider for specific requirements.
