ABB SB822 3BSE018172R1 AC 800M Rechargeable Battery Unit

Description

The ABB SB822 is an external rail-mounted backup energy component engineered to preserve volatile application logic and database memory inside AC 800M controller configurations during main line power blackouts. Operating as a dedicated rechargeable battery unit, this hardware delivers a regulated 3.6 VDC output profile, sustaining critical execution states and preventing data loss within distributed control system node processors.

The SB822 assembly contains a specialized lithium-ion cell core complete with an integrated charging interface, a local 24 VDC connection block, and a dedicated TK821V020 system interface cable link. Cataloged under product ID 3BSE018172R1, this smart auxiliary backup source coordinates with System 800xA and Compact Product Suite power modules to manage memory hold-up sequences across manufacturing execution networks without risking logic degradation.

Features

• Lithium-Ion Core Technology: Features a long-life internal cell containing approximately 0.8 g of lithium metal equivalent to ensure high-density charge holding capacity.
• Integrated Charging Management: Utilizes a dedicated 24 VDC power interface connection to regulate internal charge state parameters dynamically.
• Complete Interface Kit: Packaged together with the necessary TK821V020 data connection cable to enable rapid deployment at the controller node.
• Rail-Mounted Hardware: Built within a compact housing optimized for mounting directly on standard hardware tracks inside high-density automation panels.

Applications

• Volatile memory and parameter preservation for ABB AC 800M processors across System 800xA 4.1, 5.0, 5.1, and 6.0 control architectures.
• External backup energy support for modular controller stations deployed in the Compact Product Suite platform.

Empirical Engineering Insights

Alternative Models & Compatibility

The SB822 backup block is backwards-compatible across multiple generations of AC 800M controller setups including versions 4.1 through 6.0. It functions as a direct component swap for older restricted battery configurations. When substituting an old unit, always use the fresh TK821V020 link cable included in the kit to verify proper current delivery parameters and eliminate structural connection decay at the module bus interface.

Application Pitfalls & Engineering Notes

Deploying this lithium-based backup device inside non-ventilated electrical bays where surrounding parameters exceed normal operating ranges will accelerate internal cell degradation. This can lead to reduced hold-up duration limits or immediate premature block capacity failure. System diagnostics status bits should be mapped in the automation engineering software tool to actively track battery health state flags and trigger maintenance warnings well before cell exhaustion occurs.

Commissioning & Wiring Tips

During initialization, verify that the 24 VDC auxiliary supply lines are connected correctly to the charging block input port. Without this active current path, the internal lithium cell will not charge and will drain down rapidly under static system states. Keep the interface loop cable separated from close tracking alongside high-amperage variable speed drive outputs to shield the internal tracking lines from electromagnetic distortion vectors.
