Product Overview

The ABB SB822, identified by part number 3BSE018172R1, is a mission-critical energy storage module specifically engineered for the AC 800M controller family. Functioning as a high-reliability backup power source, this unit ensures the retention of volatile memory (RAM) and the continuity of the real-time clock during primary power failures. By integrating advanced cell chemistry, the SB822 prevents the loss of sensitive application software and process data, eliminating the need for cold-start reloads after electrical disruptions. The module is designed for standard DIN-rail mounting within the control cabinet, offering a compact and maintenance-free solution for safeguarding the operational integrity of Advant OCS and System 800xA distributed control architectures.

Strategic Process Utility & Field Usage

In Continuous Process Industries, such as chemical refining or pharmaceutical manufacturing, the SB822 is indispensable for maintaining the state of the Advant Controller. In the event of a facility-wide power fluctuation, the battery unit provides the necessary bridge power to keep the controller's internal registers active. This allows the system to resume complex batch sequences exactly where they were interrupted once power is restored, preventing the loss of expensive raw materials and reducing the time required for system recovery.

Within Critical Infrastructure and Data Centers, this battery unit supports the AC 800M’s role in power management and environmental control. Its long service life and high energy density ensure that the control logic governing cooling systems and emergency switchgear remains powered during the transition to secondary generators. The maintenance-free nature of the SB822 is a significant advantage in these high-availability settings, as it reduces the frequency of manual inspections and lowers the total cost of ownership for the control system.

For Remote Substations and Automated Robotics, the SB822 offers a ruggedized backup solution that performs reliably across a wide temperature spectrum. It is particularly valued in unmanned locations where external power may be inconsistent. By protecting the controller's memory from corruption during unexpected shutdowns, the unit ensures that telemetry and remote command capabilities are available immediately upon power-up. Its robust housing protects the internal cells from the vibrations and electrical noise typical of heavy machinery and energy distribution environments.
