ABB TA521 – Lithium Battery Accessory for AC500 V3 PLC Real-Time Clock & Memory
Description:
The TA521(full part number 1SAP180300R0001)is an exclusive accessory developed by ABB,categorized as a lithium button cell battery module for industrial control systems.It is engineered specifically to provide zero-voltage-safe backup power for the remanent memory and real-time clock(RTC)of ABB AC500 V3 series CPU modules,and it is the only accessory approved by ABB for this critical function.Encapsulated for industrial durability,it ensures critical operational data remains intact even during unexpected power outages,eliminating the risk of costly system resets.
Application Scenarios:
A mid-sized automotive parts manufacturer in Central Europe relied on 12 ABB AC500 V3 PLCs(PM5670 CPUs)to control its automated assembly lines,but faced recurring issues with production data loss and clock desynchronization after power failures.Without a dedicated backup power source,each outage forced technicians to reconfigure production parameters and recalibrate timestamps,leading to 45–60 minutes of downtime per incident and occasional batch errors.After integrating TA521 modules into each CPU,the manufacturer saw immediate results:remanent memory(storing production recipes and cycle counts)and RTC data remained fully intact through power disruptions.Downtime from outages dropped to less than 5 minutes(only for system restart),and batch errors caused by data loss were eliminated entirely.The plant manager noted,“The TA521 turned a persistent operational headache into a non-issue—we no longer fear unplanned power cuts disrupting our workflow.”

Technical Principles and Innovative Values:
Innovation Point 1:Encapsulated Zero-Voltage-Safe Design–Unlike generic PLC batteries that risk voltage spikes,the TA521 features an encapsulated structure that delivers stable,zero-voltage-safe power to sensitive CPU components.This design eliminates the risk of electrical damage to the AC500 V3’s memory circuits,a common issue with third-party battery replacements.
Innovation Point 2:ABB-Exclusive Compatibility–The TA521 is engineered to integrate seamlessly with AC500 V3 CPUs,with a form factor and power profile tailored to these modules.Generic batteries often require adapters or modify voltage output,leading to 30%more data corruption incidents according to industrial maintenance reports—an issue the TA521 eliminates entirely.
Innovation Point 3:Extended Temperature Resilience–With an operating range of-20°C to 60°C,the TA521 outperforms standard lithium button cells(typically limited to 0°C to 45°C).This makes it reliable in cold storage facilities or high-heat manufacturing areas,where generic batteries fail 2–3 times more frequently.
Innovation Point 4:Low Self-Discharge for Longevity–The TA521’s lithium chemistry minimizes self-discharge,maintaining 80%of its capacity after 2 years of standby.This doubles the service life of average PLC backup batteries,reducing maintenance frequency and costs.
Application Cases and Industry Value:
Case 1:Food and Beverage Packaging Plant–A German food packaging facility using 8 ABB PM5650 CPUs struggled with expired production timestamps and lost recipe data after weekly cleaning-related power shutdowns.Third-party batteries failed to maintain RTC accuracy,leading to non-compliant labeling and regulatory fines.After switching to TA521 modules,timestamp accuracy was maintained to the second,and recipe data remained intact through 50+planned shutdowns.The plant avoided€12,000 in monthly fines and reduced maintenance time by 8 hours per month.
Case 2:Pharmaceutical Manufacturing Line–A U.S.-based pharmaceutical company required uninterrupted batch data logging for FDA compliance.Its AC500 V3 system suffered data gaps during power fluctuations until installing TA521 units.The modules’stable backup power ensured 100%batch data retention,passing two consecutive FDA audits with no findings.The plant’s maintenance supervisor stated,“The TA521 is a small component with huge compliance value—we can’t operate our validated lines without it.”

Installation,Maintenance,and Full-Cycle Support:
Installation of the TA521 is straightforward and requires no specialized tools.First,power off the AC500 V3 CPU to avoid data risk.Locate the dedicated battery slot on the CPU module—designed exclusively for the TA521—and insert the module until it clicks into place.Power the CPU back on,and the system automatically recognizes the TA521 and confirms backup power activation.No software configuration is needed,making installation completed in 5 minutes or less even by junior technicians.
Routine maintenance for the TA521 is minimal.Monthly checks via the AC500’s HMI confirm battery status,with a low-power alert triggering 30 days before capacity drops below functional levels.Replacement involves the same simple steps as installation,with no system reconfiguration required.Critical safety notes:do not short-circuit or attempt to recharge the TA521(a primary battery),as this risks overheating or leakage—issues prevented by the module’s built-in safety mechanisms.
