Product Description

The Siemens 6ES7953 MMC Module (6ES7953-8LJ31-0AA0) is a durable SIMATIC S7-300 Storage Card designed for reliable data retention and program storage in PLC systems. This PLC Memory module operates within an industrial temperature range of 0°C to 60°C and supports a 3.3V supply voltage. It features a non-volatile flash memory for backup-free operation, ensuring data preservation during power loss. Compatible with SIMATIC S7-300 CPUs, it directly interfaces via the PLC’s integrated MMC slot without requiring external adapters. Ideal for automation, manufacturing, and process control applications, its key advantages include high shock/vibration resistance, long-term data integrity, and plug-and-play compatibility. Limitations include dependency on Siemens-specific hardware for read/write operations. The compact design (approx. 32 x 24 mm) ensures seamless integration into industrial control systems.
