Applications
The expanded battery module is ideal in industrial control systems where power interruptions must not compromise retained logic or timestamp data. Typical use cases include:
-
Real-Time Clock Support: Maintaining accurate time data during power loss
-
Data Retention: Preserving ladder logic and register contents that require backup power
-
Controlled Restart: Supporting orderly PLC restart with minimal data loss after outages
-
Critical Process Systems: Power-sensitive systems in utilities, manufacturing, and infrastructure
By enhancing backup endurance, this module strengthens system resilience against brief or extended power disturbances.
Advantages
-
Extended Backup Life: Provides longer retention time for PLC memory and real-time clock compared to standard batteries
-
Maintenance-Free Design: Sealed battery reduces service needs and eliminates frequent replacement cycles
-
System Compatibility: Works with Series 90-30 and Rx3i PLC architectures
-
Supports Critical Data Integrity: Reduces risk of losing time, configuration, or state data after power loss
-
Compact and Reliable: Small footprint and rugged construction suitable for industrial cabinets
These features help ensure that essential system data and timestamps are preserved, even under variable power conditions.
