ABB SB822 3BSE018172R1 is an AC 800M rechargeable battery unit designed to preserve processor memory when normal power is lost.
Selection depends on the installed PM8xx processor because ABB publishes different minimum backup times for different processor groups when the battery is fully charged.
Before installation or replacement, verify the processor model, DIN-rail mounting, ambient temperature, TK821V020 cable, battery charge and approved lithium-battery handling procedure.
