ABB SB822 Redundant Power Supply Module

Description

ABB SB822 Redundant Power Supply Module

The ABB SB822 (Product ID: 3BSE018172R1) is an external, DIN-rail mounted Rechargeable Battery Unit designed specifically for the System 800xA / AC 800M controller family. It functions as an external backup power source to provide extended memory retention for the controller’s CPU when primary power is lost.

Technical Parameters

Backup Time Performance

The backup duration provided by a fully charged SB822 depends directly on the specific AC 800M CPU model being supported:

• PM851 / PM856 / PM860: Minimum 100 hours
• PM861A: Minimum 240 hours
• PM864A / PM865: Minimum 490 hours

Product Advantages

• Extended Retention Time: Offers a significantly longer memory backup duration (up to 490 hours) compared to standard internal controller batteries.
• Cost-Efficient & Sustainable: Utilizing a rechargeable Lithium-Ion chemistry eliminates the frequent replacement and disposal costs associated with non-rechargeable cells.
• Space-Saving DIN-Rail Mounting: Can be easily mounted on standard rails inside the control cabinet, freeing up internal space within the primary controller slot.
• Onboard Status Diagnostics: Features localized LED indicators for fast troubleshooting:
  • Power LED: Indicates the incoming 24V DC supply is within valid specifications.
  • Charge LED: Indicates that battery replenishment is currently in progress.
• Robust Environmental Integrity: Rated for ISA-S71.04 G2 corrosive atmospheres, providing reliability in harsh industrial environments.

Important Considerations & Precautions

• Internal Battery Removal: When installing the SB822 external unit, you must remove the internal battery from the AC 800M processor unit. The system’s status monitoring mechanism can only track one battery source at a time.
• Lifespan & Maintenance: The battery module must be replaced after 3 years of normal operation or after a maximum of 400 discharge cycles, whichever occurs first.
• Air Quality & Heat Dissipation: Ensure ambient temperatures remain between 0^\circC and +55^\circC to maximize battery chemistry health and prevent accelerated degradation.
• Dangerous Goods Handling: Due to containing Lithium-Ion cells, the unit falls under UN Class 9 transport regulations (UN3481-PI967). Care must be taken during shipping, and the battery must never be disposed of in fire.

Product Applications

The SB822 is exclusively utilized within the ABB Ability System 800xA automation platform:

• Process Automation Plants: Ensuring application logic, runtime parameters, and historical event logs are not wiped out during unexpected site-wide power outages.
• Critical Infrastructure Control: Deployed in remote control cabinets where a power failure could leave an AC 800M controller unpowered for multiple consecutive days before maintenance personnel arrive.
• Manufacturing Control Panels: Providing high-density cabinet backup power architecture for complex multi-CPU processing lines.
