1SAP180300R0001 stands for TA521, a lithium battery backup module dedicated to ABB AC500 PLC series. Equipped with connecting wires and dedicated connector, it supplies backup power when the main power is cut off. It protects internal RAM data and real time clock of the PLC, and prevents loss of user programs, operating data and time information. This module is compatible with AC500 V2 and AC500 V3 CPU modules, and serves as an essential accessory for reliable long term operation of PLC systems.

1SAP180300R0001 is the complete ABB part number. TA521 is the product model of the backup battery assembly. 180300 represents the base platform for AC500 series backup batteries, and R0001 refers to the hardware revision. This product adopts CR2450 coin type lithium battery with pre assembled cables and connectors, which is specially developed for data retention of AC500 PLC.

The battery type is lithium manganese dioxide coin cell CR2450 with a rated voltage of 3.0 V DC and typical capacity of 540 mAh. The typical service life reaches 5 to 7 years under ambient temperature of 25 degrees Celsius. The operating temperature ranges from minus 20 degrees Celsius to 60 degrees Celsius. The overall dimension including cables is approximately 170 mm by 100 mm by 8 mm, and the total weight is about 0.01 kilogram. It is a non rechargeable disposable battery. The product has passed CE and RoHS certifications. It is fitted with protected cables and a dedicated 2 pin plug for direct connection.

The module consists of a sealed CR2450 battery unit and extended cables. One end is connected to the battery body, and the other end is a 2 pin dedicated plug which can be directly inserted into the dedicated battery socket on AC500 CPU. It requires no external power supply. The module is installed inside the control cabinet in flat placement mode. It starts to work automatically once the main power of PLC is disconnected, and maintains normal power supply for internal storage and clock circuit.

It retains all data stored in PLC RAM and prevents program and parameter loss after power failure. It keeps the real time clock running continuously to avoid time reset after system restart. It provides stable backup power to ensure the PLC system can resume normal operation quickly after power recovery. The plug and play design enables simple installation and replacement without additional configuration.

It is widely used in normal operation, commissioning and routine maintenance of AC500 PLC systems. It is suitable for automated production lines, packaging machinery and material handling equipment. It is applied to industrial sites that have strict requirements on data integrity and cannot accept program loss caused by sudden power cut. It is also applicable to long running industrial equipment which is inconvenient for frequent shutdown and inspection.

Make sure the PLC is fully powered off before installation to avoid short circuit. Insert the plug into the corresponding battery port on CPU and guarantee firm connection. Replace the battery timely when the system prompts low battery voltage or when it reaches the end of service life. Dispose of waste lithium batteries in accordance with local environmental regulations instead of random discarding. Do not place the module in high temperature, humid or corrosive environments. Do not squeeze or damage the battery shell and cables. Replace the whole module directly if any fault occurs.
