Description
Product Overview
The ABB SB822 3BSE018172R1 is an external rechargeable battery unit designed for ABB AC 800M controllers used in industrial automation and System 800xA installations. Mounted on a DIN rail inside the control cabinet, it contains a lithium-ion battery and connects to the controller through a dedicated cable. The package includes a 24 V DC connector and the TK821V020 connection cable.
The SB822 provides backup power for supported controller functions when the normal power source is interrupted. Its purpose is to help preserve the controller’s battery-dependent data or state, as defined by the specific AC 800M hardware and configuration. It should not be treated as a general-purpose 24 V DC UPS capable of powering an entire controller rack or field instrumentation.
For maintenance teams, battery condition is important even when the controller is otherwise operating normally. A depleted or aging battery may compromise the backup function during a power interruption. When replacing an SB822 3BSE018172R1, verify the complete part number, connector arrangement, cable condition, and controller compatibility. Also confirm whether the supplied unit includes the battery and cable, rather than assuming all listings represent the same package.

SB822 3BSE018172R1
Major Features and Advantages
External battery backup
The SB822 3BSE018172R1 provides a dedicated battery backup source for compatible AC 800M controller functions. Its external design allows the battery unit to be installed on a DIN rail instead of occupying a controller slot.
Rechargeable lithium-ion battery
The integrated lithium-ion battery is designed for repeated charging during normal operation. Battery age, charge condition, ambient temperature, and maintenance history can affect its ability to provide backup when required. A replacement should be evaluated by condition and service requirements, not appearance alone.
Dedicated controller connection
The included TK821V020 cable provides the intended connection between the battery unit and compatible controller hardware. Check the cable and connector before installation; do not substitute an arbitrary cable based only on physical fit.
Compact cabinet installation
With an approximately 85.8 mm width and IP20 protection, the SB822 is intended for installation inside a suitable electrical cabinet. IP20 does not provide protection against water or conductive dust, so the unit must be installed in an environment appropriate for its enclosure rating.
Defined electrical ratings
ABB specifies a 3.6 V rated output and a maximum output current of 0.05 A. These ratings describe the battery unit’s output and should not be confused with the 24 V DC connection used by the system. Confirm the correct wiring and controller interface before commissioning.
Typical Applications
The ABB 3BSE018172R1 is intended for compatible AC 800M controller installations, including:
- ABB System 800xA distributed control systems
- Industrial process-control cabinets
- Controller battery-backup maintenance
- Replacement of an aged or failed unit
- Preventive maintenance for existing AC 800M installations
Its suitability depends on the exact controller hardware and the backup functions supported by that configuration.
Related Products
- TK821V020 — connection cable supplied with the .
- ABB AC 800M controllers — compatible controller platform, subject to the specific controller model and hardware configuration.
- ABB SB821 — a different battery-unit model; verify the controller requirements before considering it as an alternative.
Installation and Maintenance
- Verify the part number: Confirm 3BSE018172R1 on the unit label.
- Inspect the package: Check whether the battery unit, 24 V DC connector, and TK821V020 cable are included.
- Confirm compatibility: Review the AC 800M controller manual and battery-interface requirements.
- Inspect battery condition: Check for damage, swelling, leakage, corrosion, or other signs of deterioration. Do not install a damaged lithium-ion battery.
- Follow approved replacement procedures: Observe the controller manufacturer’s instructions and site isolation requirements. Determine whether the controller must be powered down before disconnecting the battery.
- Verify operation: Check battery status and controller diagnostics after replacement, then confirm the backup function according to the approved maintenance procedure.
Product Assurance
For the ABB 3BSE018172R1, verify the full part number, battery condition, included accessories, and supplier test records before purchase. If the unit is used or refurbished, ask for information about battery age and functional testing; an intact enclosure does not establish remaining battery capacity.
Procurement note: Confirm that the item is a complete rechargeable battery unit and that the included cable is suitable for the target AC 800M controller. Do not treat the as a general-purpose power supply or assume it provides backup power for the entire control system.
