Features:
- Serves as the critical bridge between the 3.6 V backup power source and the S7-400 CPU memory architecture
- Integrates the functionality of long-duration DC power storage with automated memory preservation capabilities
- Functions alongside the PS 405 and PS 407 power supply modules across multiple current ratings
The SIEMENS 6ES7971-0BA00 SIMATIC S7-400 Backup battery functions as the dedicated memory retention component within an S7-400 automation rack, delivering sustained 3.6 VDC power to safeguard essential CPU data during primary power failures. It persistently maintains backup energy supply (3.6 V/2.3 AH) to protect real-time clock functions, diagnostic buffers, counter values, and user program storage when the main PS 405 or PS 407 power supply encounters interruption. Uninterrupted data integrity comes standard with the 6ES7971-0BA00, guaranteeing that all volatile operational parameters remain preserved throughout unexpected electrical outages. The 6ES7971-0BA00 has been purpose-built to ensure production continuity in demanding industrial environments where information preservation directly impacts operational efficiency.
The 6ES7971-0BA00 delivers vital backup power services essential to the complete S7-400 control ecosystem, representing a fundamental element of the data security chain, significantly influencing the correct, routine performance of memory-critical automation tasks. A single 6ES7971-0BA00 backup battery is mandated for each compatible power supply unit to secure ongoing data protection. The 6ES7971-0BA00 is engineered for seamless integration into the PS 405 4 A/10 A/20 A and PS 407 4 A/10 A/20 A power supply housings, fitting exclusively into the designated battery slots within these assemblies.
For enhanced system dependability, the 6ES7971-0BA00 SIMATIC S7-400 Backup battery sustains uniform output characteristics across its operational lifespan. Beyond conventional memory safeguarding, this battery arrangement enables immediate power handover to internal memory circuits without operator action. The 6ES7971-0BA00 backup mechanism implements protection through the integrated circuitry defined within the power supply specifications. Through this approach, the battery subsystem constantly evaluates the condition of the reserve power source. Should the system identify that the primary power supply has ceased delivering stable voltage to CPU memory elements, the 6ES7971-0BA00 will autonomously sustain the electrical load to crucial memory sectors and retain all configuration settings without necessitating manual recovery procedures.
The 6ES7971-0BA00 SIEMENS Backup battery may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
