NEW 6ES7953-8LJ31-0AA0

Key Specifications & Features:

• Storage Capacity: Provides 64 MB of flash memory, offering ample space for large user programs, complex configuration data (such as hardware settings, network parameters, and process variables), and auxiliary files required for industrial automation tasks.
• Core Function: Acts as the primary non-volatile storage for S7-300/S7-400 CPUs, which lack built-in program memory. The CPU reads the operating program, system configurations, and data blocks directly from the MMC during startup, ensuring consistent operation and preserving data even when power is disconnected.
• Compatibility: Specifically engineered for use with SIMATIC S7-300 CPUs (e.g., 312, 314, 315, 317 models) and selected S7-400 CPUs, integrating seamlessly with these controllers to support their programming and operational requirements.
• Industrial-Grade Reliability: Built to withstand harsh industrial environments, with resistance to vibration, shock, and electromagnetic interference (EMC) in compliance with international standards (e.g., IEC 61131-2). It operates reliably within a temperature range of -25°C to +70°C, making it suitable for demanding industrial settings.
• Data Integrity: Utilizes flash memory technology to ensure stable, long-term data retention (typically up to 10 years without power) and supports multiple read/write cycles, ensuring durability in continuous operation.
• Ease of Use: Designed for simple installation and removal from the CPU’s memory card slot. It works with Siemens TIA Portal (STEP 7) software for program transfer, allowing engineers to easily load, update, or back up controller data.
