6ES7953-8L31-0AA0 SIEMENS SIMATIC S7 Micro Memory Card

Product Dimensions：

The Siemens SIMATIC S7 Micro Memory Card (MMC) is a crucial component for Siemens S7-300, C7, and ET 200 series PLCs. It serves as the primary storage medium for the PLC’s program, data, and configuration, enabling efficient and reliable operation of industrial automation systems.

Product Details

The Micro Memory Card is a compact, removable flash memory card designed specifically for Siemens SIMATIC controllers. It uses 3.3V NFlash technology and comes in various storage capacities. The MMC stores the entire PLC project, including the user program, data blocks, function blocks, and hardware configuration. When inserted into a compatible Siemens CPU, the program automatically loads from the MMC, allowing the PLC to execute its defined control tasks.

Key Features:

• Non-volatile Memory: Retains data even when power is removed, ensuring program integrity.
• Plug-and-Play Functionality: Programs can be easily transferred to a new or replacement CPU by simply inserting the pre-loaded MMC.
• Compact Size: Small form factor for convenient integration into PLC systems.
• Robust Design: Built to withstand industrial environments.
• Different Memory Sizes: Available in various capacities (e.g., 64KB, 2MB, 4MB, 8MB, 512KB) to suit different application requirements.
• Automatic Program Loading: When inserted into a compatible CPU, the PLC automatically loads the program and configuration from the MMC.
