6ES7954-8LC03-0AA0 is a memory card produced by Siemens, specifically designed for S7-1×00 CPUs and SINAMICS drives. Here is a detailed description:
- Basic Information: It belongs to the SIMATIC S7 product series, with a product model of 6ES7954-8LC03-0AA0. The memory type is Flash – EPROM, and it operates at 3.3V.
- Storage Capacity: The memory card has a capacity of 4MB, which can provide sufficient space for storing program codes, data records, and other information in industrial automation systems. It can meet the needs of small – scale projects, such as the built – in load memory of the 1215PLC is also 4MB.
- Performance Characteristics: It supports at least 500,000 write or delete operations, ensuring reliable data storage and modification in long – term use. After the final programming, it can retain data for 10 years, which is very important for the long – term storage of key industrial data.
- Physical Dimensions: The memory card is compact, with a width of 24 mm, a height of 32 mm, and a depth of 2.1 mm, weighing about 3 g. This small size makes it easy to install in PLC devices, and it will not take up too much space in the control cabinet.
- Compliance and Certification: It complies with the RoHS directive, indicating that it meets the relevant environmental protection requirements and is environmentally friendly.
- Application Scenarios: It is mainly used in SIMATIC S7 – 1200 basic controllers and S7 – 1500 advanced controllers. These controllers are widely used in various industrial automation scenarios, such as factory production lines, automated control systems in the energy sector, and building automation systems. The memory card can help these controllers store programs and data, and play an important role in ensuring the normal operation of the automation system.
