ABB SB822 3BSE018172R1 Module

Brand Overview

• Brand: ABB (Asea Brown Boveri)
  * About the Brand: ABB is a leading global technology company specializing in electrification and industrial automation. Their control system peripherals and energy preservation accessories are built to rigorous standards, guaranteeing maximum data safety and uptime in continuous process environments.

Product Identification

• Model Number: SB822
  * Product ID / Part Number: 3BSE018172R1
  * Product Type: Rechargeable Battery Backup Unit / RAM Memory Backup Module
  * Product Family: Advant OCS / System 800xA Controller Accessories (specifically utilized with Advant Controller AC 400 series or related processing nodes)

Technical Specifications

• Primary Function: Provides reliable electrical energy backup directly to a central processor module’s volatile RAM memory. This ensures that application software, runtime databases, configuration metrics, and execution states are safely preserved during complete power blackouts or scheduled system shutdowns.
  * Cell Chemistry: Utilizes high-end industrial rechargeable NiCd (Nickel-Cadmium) or specialized rechargeable cell blocks optimized for sustained trickle charging.
  * Nominal Output Voltage: Typically configured to match internal controller logic backplanes, delivering around 3.6 V DC.
  * Charging Interface: Automatically receives a controlled trickle recharge from the controller’s main 24 V DC backplane power while the host system is operational, keeping the cells at peak capacity.
  * Monitoring & Alerts: Connects to internal hardware diagnostic buses, enabling the primary controller CPU to constantly track battery health, charge status, and low-voltage thresholds.
  * Physical Profile: Built with a specialized slide-in or panel-mount form factor designed to fit directly alongside or inside the associated CPU assembly enclosure.

Target Industries

The SB822 is essential infrastructure in heavy continuous process industries where losing system memory parameters could halt production lines or damage machinery:

• Power Generation & Utilities: Nuclear, thermal, and hydroelectric power plant control cabinets.
  * Oil & Gas / Petrochemicals: Distributed control racks in refineries, offshore production platforms, and pipeline booster stations.
  * Metallurgy & Heavy Manufacturing: High-capacity rolling mills, blast furnaces, and casting systems.
  * Pulp & Paper Processing: Large-scale mill control rooms utilizing continuous chemical or physical processing loops.
  * Chemical Engineering: Automated batch mixing plants and continuous chemical synthesis networks.

Applications and Use Cases

• Volatile RAM Memory Protection: Retains the dynamic application software layer and complex configuration databases inside the central controller module when auxiliary factory mains fail.
  * Cold-Start Prevention: Drastically reduces system recovery times during a major power restoration sequence by enabling the controller to boot up instantly using preserved runtime memory, completely avoiding the need to manually reload software routines from scratch.
  * System Diagnostic Signaling: Works with the host PLC/DCS software architecture to trip a maintenance warning on the supervisory HMI screen the moment the battery fails a health self-test, prompting preventative maintenance before a total power outage takes place.
  * Industrial Lifecycle Upgrades: Installed as a periodic, exact drop-in replacement part to maintain memory preservation stability inside legacy ABB Advant control panels.
