Key Features

• Extended Long‑Term Memory Retention: Delivers up to 75 months of continuous RAM backup for most GE PLC CPUs, eliminating frequent battery replacements and ensuring data integrity over multi‑year periods.
• High‑Density Lithium Cell Technology: Provides 15 Ah capacity at 3 VDC, offering superior energy density and longer service life compared to standard alkaline or nickel‑cadmium batteries.
• Sealed Industrial‑Grade Construction: Flame‑retardant ABS housing and sealed internal components protect against dust, moisture, and electrical interference, ensuring reliable operation in factory floor environments.
• Built‑In Short‑Circuit Protection: A factory‑sealed 1 A fuse safeguards the module and connected PLC from damage due to wiring faults, overloads, or reverse polarity.
• Maintenance‑Free Operation: No charging required; the lithium cell powers the PLC’s volatile RAM directly, with no scheduled maintenance or routine servicing needed over its 10‑year shelf life.
• Wide Environmental Tolerance: Operates reliably across 0°C to +60°C and 5%–95% non‑condensing humidity, adapting to extreme temperature and moisture conditions in industrial facilities.
• Plug‑and‑Play Compatibility: Directly replaces the standard CPU battery in Series 90‑30, Series 90‑70, and PACSystems PLCs, requiring no additional software or configuration changes.
• Dual Mounting Flexibility: Supports both panel‑mount and DIN‑rail mount (with optional bracket), integrating seamlessly into new or existing control cabinet layouts.
• Global Safety & Environmental Compliance: Meets CE, cULus, and RoHS standards, ensuring safe deployment in global industrial applications and compliance with environmental regulations.

Applications

• Legacy PLC System Maintenance: Replaces aging standard batteries in GE Series 90‑30/90‑70 PLCs, extending the service life of legacy control systems and avoiding costly hardware upgrades.
• Critical Process Control: Ensures data integrity in manufacturing, chemical, and pharmaceutical plants, where unexpected power losses could result in lost production data or safety hazards.
• Uninterrupted Program Retention: Protects user programs and configuration data in water/wastewater treatment, power generation, and oil/gas facilities, where systems may be shutdown for extended maintenance periods.
• Remote & Unattended Facilities: Ideal for remote pumping stations, pipeline monitoring, and off‑grid industrial sites, where access for battery replacement is limited or costly.
• PACSystems Modernization: Provides extended backup power for GE PACSystems RX3i/RX7i controllers in retrofit projects, combining modern PLC hardware with long‑term data retention reliability.
• OEM Equipment Integration: Embedded in custom industrial machinery and automation systems requiring maintenance‑free, long‑term memory backup for GE PLC‑based controls.
