Functional Features

• Extended Memory Backup: Provides significantly longer backup time compared to standard PLC batteries, preserving critical data including user logic, PID settings, I/O configurations, and real-time clock settings for up to 75 months on most CPU models.

• High Energy Density Chemistry: Utilizes lithium-thionyl chloride technology for stable voltage output and low self-discharge rate, ensuring reliable performance over extended periods.

• Broad System Compatibility: Fully compatible with all IC693 power supplies and IC697 CPU battery connectors, functioning as a drop-in replacement for the standard IC693ACC301 battery without hardware or software modifications.

• Low Battery Indication: Integrates with the PLC CPU module’s BATT LED indicator, which illuminates when battery voltage drops below the threshold (typically 2.7 V DC), providing early warning for scheduled replacement.

• Industrial-Grade Construction: Housed in flame-retardant ABS plastic with an operating temperature range of 0°C to 60°C, suitable for demanding industrial environments.

• Durable Service Life: Extended shelf life of 7 to 10 years when stored at room temperature, reducing replacement frequency and maintenance costs.

Application Scenarios
This battery module is deployed in industrial control systems where data integrity during power interruptions is critical:

• Manufacturing Automation: Preserves PLC programs for production lines, conveyor systems, and robotic work cells, preventing costly reprogramming downtime after power outages.

• Remote Oil and Gas Facilities: Maintains control logic for wellhead monitoring and pipeline systems at unattended sites where power restoration may take extended periods.

• Water and Wastewater Treatment: Retains chemical dosing schedules, pump control parameters, and SCADA configurations to ensure regulatory compliance and consistent water quality.

• Power Generation and Distribution: Protects control system logic for generators, switchgear, and substation automation equipment during grid failures.

• Process Industries: Safeguards batch recipes, process setpoints, and safety interlock configurations in chemical, petrochemical, and food processing plants.

Important Clarification on Search Results
The search results for IC693ACC302B reveal significant contradictions across third-party distributor websites. While the majority of sources correctly identify this as a lithium backup battery module for Series 90-30 PLCs, other listings contain entirely incompatible product descriptions. These erroneous descriptions include a relay output module with 8 channels, an analog current input module with 4 channels, and a 2-axis servo drive module for PACSystems RX3i. These conflicting descriptions from non-authoritative sources underscore the importance of consulting official GE documentation or verifying the physical module label for accurate identification.
