Industrial Control System Applications

This rechargeable battery unit addresses critical backup power requirements across distributed control architectures where system availability directly impacts production continuity and process safety:

• S800 I/O Module Protection: Provides backup power to distributed I/O modules in remote locations, maintaining field data acquisition and control output states during power interruptions in process control networks
• AC 800M Controller Backup: Ensures continuous operation of controller processors, preserving control logic execution, alarm states, and communication integrity during brief power outages or switchover events
• Critical Process Continuity: Enables orderly shutdown sequences in batch processes, reactor control, and safety-critical applications where abrupt power loss could result in product loss or equipment damage
• Remote Site Reliability: Supports unmanned facilities, offshore platforms, and remote pump stations where power quality is unreliable and backup power extends system availability between maintenance visits
• Data Integrity Protection: Maintains NVRAM power and configuration memory during power cycling, preventing loss of calibration data, control parameters, and historical buffers in process automation systems
• Redundant System Support: Complements redundant power supply architectures by providing additional backup layer for critical control functions requiring maximum availability
• Emergency Shutdown Systems: Powers safety instrumented systems during emergency conditions, ensuring protective functions remain operational until safe plant state is achieved

S800 I/O System Integration

The SB822 battery unit mounts directly in ABB S800 I/O racks via standard DIN rail mounting, connecting to the rack backplane through integrated connectors. The battery automatically charges when mains power is available and seamlessly transitions to backup mode during power failures. Integration with AC 800M controllers enables battery status monitoring, low battery alarms, and predictive replacement notifications through system diagnostics.
