Functional Features

• Extended Memory Backup: Provides a significantly longer backup time for volatile CPU memory compared to standard coin-cell batteries .

• Smart Low-Battery Detection: This is a core function that distinguishes it from standard batteries. The module’s monitoring circuit provides a “Low Battery” state indication. The output voltage is above 2.5 V during the “good” state and drops below 2.5 V in the “low” state, which lasts for 15 days across all compatible CPU models before the battery is fully drained .

• Backup Duration Example: When connected to an IC695CPU310, it can provide up to 185 days of memory backup in its good state, followed by a 15-day low state warning period .

• Service Life and Replacement: The module should be replaced every 2 years or immediately once a Low Battery fault is logged in the CPU, whichever occurs first .

• Installation Advisory: To maximize battery life, it is recommended to install a fresh battery only after power has been turned on to the connected CPU. Once the enabling adapter cable is connected, the battery begins to drain, even if not attached to a CPU .

Application Scenarios
This module is a critical component for maintaining data integrity in industrial automation systems:

• Power Generation: Protects control logic, configuration, and register data in PACSystems controllers managing turbines and generators during power outages.

• Industrial Automation: Ensures that production lines, robotic cells, and assembly machinery retain their programs and operational parameters through unexpected shutdowns.

• Process Control: Preserves batch recipes, setpoints, and safety configurations critical to operations in chemical, petrochemical, and water treatment plants.

• Remote Installations: Provides critical memory backup for controllers in oil and gas pipelines or other unattended sites where power interruptions may last longer than what a standard battery can support.
