1SAP180300R0001
Product ID
#181
The ABB 1SAP180300R0001 is the order code for the TA521: a lithium battery set consisting of a CR2450 primary lithium battery and adapter cable, used to retain RAM data in AC500 PLC CPUs during power loss. ABB's own ordering information lists it as TA521 battery for AC500 V2 CPUs PM57x, PM58x and PM59x, explicitly stating it is not for PM595, and documentation indicates TA521 covers AC500 V3 PM56xx CPUs through its cable. Distributor listings show additional compatible models including PM55x, PM56x, PM562, PM564, PM590 and PM595, which reflects different sourcing notes - follow ABB's exclusion for PM595 and confirm per CPU. Battery spares are consumables and should be stocked before power loss events.
