IC693ACC302A | GE Fanuc | High-Capacity Lithium Backup Pack

Product Description

High-Capacity Memory Retention for PACSystems

The GE Fanuc IC693ACC302A (Model IC693ACC302) is a high-capacity auxiliary battery module engineered for the PACSystems RX3i and Series 90-30 PLC families. Unlike standard internal backup cells, this auxiliary pack is designed for long-term memory retention of volatile CMOS RAM. It ensures that critical user logic, system configurations, and register data remain intact during extended power outages or seasonal equipment shutdowns. The IC693ACC302A is an essential component for high-availability systems where data loss can lead to significant operational delays or safety risks.

Technical Performance and Integrity

Utilizing advanced Lithium-Thionyl Chloride (Li-SOCl2) chemistry, the IC693ACC302A provides a massive 15,000 mAh capacity, which is significantly higher than the standard 2,500 mAh internal batteries. This module outputs a stable 3.0V DC (with a 3.6V peak open-circuit voltage) to the CPU memory circuit through a factory-terminated wire lead and keyed connector. The ruggedized housing is built to withstand the electromagnetic interference and mechanical vibrations common in industrial environments, maintaining a gas-tight electrical connection over its multi-year service life.
