IC693ACC302B | GE Fanuc | 15000mAh Lithium Backup Battery

Product Description

High-Capacity Memory Retention for Series 90-30

The GE Fanuc IC693ACC302B (Model IC693ACC302) is a high-capacity auxiliary lithium battery module designed specifically for the PACSystems RX3i and Series 90-30 PLC CPU families. This module serves as the primary backup power source for volatile CMOS RAM, ensuring that user programs, register data, and system configurations are preserved during loss of system power. Unlike standard internal batteries, the IC693ACC302B provides a significantly higher capacity, making it the ideal choice for applications where long-term shutdown periods are expected or where data integrity is safety-critical.

Technical Superiority and Reliability

The IC693ACC302B utilizes high-energy lithium-thionyl chloride chemistry, providing a stable 3.0V DC (nominal 3.6V under certain load profiles) to the CPU's memory circuit. It features a factory-terminated wire lead and connector assembly for a secure, vibration-resistant connection. While standard batteries offer limited ampere-hour ratings, the auxiliary module is engineered for extended service life, often reaching up to 15,000 mAh in specific high-capacity variants. This ensures that the PLC can maintain its logic and state memory for extended intervals without requiring an external power source.
