ABB TA521
The ABB TA521 module is a battery module designed by ABB for the AC500 series programmable logic controllers (PLCS). It is mainly used to provide backup power for the real-time clock, parameter setting and event recording functions of the PLC in the case of PLC power failure, to ensure that the PLC can quickly resume operation after the resumption of power supply, and to retain key data.
Main functions:
Real-time clock backup: In the event of PLC power failure, power is provided to the real-time clock to ensure that time information is not lost.
Parameter Settings Backup: Protects the parameter Settings in the PLC to prevent data loss.
Event record backup: Store PLC event records for fault diagnosis and analysis.
