Product Description

The ABB 23BA22A (Ordering Code: 1KGT004800R5002) is a specialized battery-buffered SRAM module designed for ABB’s RTU560 series. It provides reliable non-volatile storage for system data, event logs, and configuration files, preserving critical information during power interruptions.

Core Features

Battery-Backed Memory
Equipped with onboard lithium batteries, the module maintains SRAM integrity without external power. This ensures seamless continuity of data and event logs, even during full system shutdowns.

High System Reliability
The module continuously monitors battery voltage and signals low-charge conditions to the RTU system. It is fully compatible with redundant RTU configurations, enabling synchronized data across primary and backup units.

Durable Industrial Design
Engineered for harsh operational environments, the module operates from -25°C to +70°C and offers robust EMC protection against electromagnetic interference near high-voltage equipment.

Ease of Maintenance and Integration
Hot-swappable design allows quick replacement or upgrades within the RTU560 subrack. Front-panel LEDs indicate operational status and alert for battery or module faults.

Technical Specifications

Applications

The 23BA22A module is used for:

• Substation automation for Sequence of Events (SOE) logging

• Power grid and utility control systems to retain configuration during outages

• Industrial automation for command output monitoring

• Data buffering for communication protocols like IEC 60870-5-104 and IEC 61850
