GE IC693ACC301 – Series 90-30 PLC 3V Lithium RAM Backup Battery Module

In stock

Product Introduction:

The IC693ACC301 is a compact, high-reliability lithium battery module manufactured by GE (now Emerson Automation) for the GE Series 90-30 PLC system. Its core purpose is to preserve volatile CMOS RAM data, user programs, configuration logic, and real-time clock (RTC) settings during main power outages, shutdowns, or maintenance events. Without this battery, all unsaved runtime data and program logic would be permanently lost, leading to system downtime, production halts, and costly reprogramming. Designed as a direct OEM replacement, it integrates seamlessly with Series 90-30 CPUs and power supplies, ensuring long-term data integrity in industrial automation environments.
