Description
Description
The Siemens 6ES7952-1AH00-0AA0 is a dedicated RAM memory card designed for the SIMATIC S7-400 automation system. This long-version memory module provides 256 KB of volatile storage capacity, essential for the operation and program execution of S7-400 CPUs. As a critical component for system configuration, it ensures the necessary memory overhead for complex control tasks and data management within the S7-400 architecture.
Features
- Compatible with SIMATIC S7-400 programmable logic controllers.
- Provides 256 KB of RAM storage capacity.
- Long-version form factor for specific S7-400 CPU slot requirements.
- Reliable data retention for runtime program variables and blocks.
Installation Guidelines
- Ensure the CPU is powered down before inserting or removing the memory card to prevent data corruption or electrical damage.
- Handle the module by its edges; avoid touching the gold-plated connector contacts to prevent contamination or oxidation.
- Ensure the card is fully seated in the designated memory slot of the S7-400 CPU.
- Verify that the CPU configuration supports the specific memory card size and type before deployment.
- Store in a static-safe environment when not in use to protect sensitive internal components.
