Siemens 6ES79521AP000AA0

Storage Architecture

Non-volatile FLASH memory with wear-leveling algorithm, supporting up to 1 million write cycles and 10-year data retention without power supply.

Mechanical Resilience

Reinforced polycarbonate housing with IP67-rated dust/water resistance and vibration resistance up to 5 g (10–150 Hz) per IEC 60068-2-6.

Hot-Swap Capability

Supports live insertion/removal in powered systems via guided slot alignment, featuring ESD protection up to 15 kV (air discharge) per IEC 61000-4-2.

Functional Features

The Siemens 6ES7952-1AP00-0AA0 RAM Memory Card allows the S7-400 PLC to increase overall performance and functionality from additional expansion:

Real Time Program Execution Data Storage: Contains 8MB of memory for storage of temporary data to execute the program in real time Application/Configuration Logging: Allows user to store configuration file changes Diagnostics Logging: Allows user to store a Diagnostic log file Product data was successfully added to your shopping cart. Volatile is what allows it to deliver high read and write speeds necessary for automations tasks with time constraints.

Battery-Backed Storage: With the addition of a back-up battery, the Siemens 6ES79521AP000AA0 has the ability to store data should there be a power cut and knock on effect with an assembly line or power grid.

Plug-and-Play Compatibility: The “long design” means you can simply plug it directly into Siemens S7-400 PLCs, reducing the need to spend time ‘racking and slotting’ during installation and system upgrades.

Associated Equipment

Enhance your Siemens 6ES79521AP000AA0 with other Siemens equipment:

S7-400 PLC Compatible: This memory card is specifically designed to be used with Siemens S7-400 series controllers, and it supports CPUs, such as 6ES7412-2XJ05-0AB0 and 6ES7416-3XL04-0AB0, to accommodate scalable automation solutions.

Power modules If you need the voltage to remain stable for the Siemens 6ES7952-1AP00-0AA0 when the supply voltage changes, then a Siemens 6ES7407-0DA02-0AA0 or equivalent is ideal.

Communications Processors: Exchange data between PLC and a SCADA system with Siemens 6GK7443-1EX30-0XE0 modules, the higher-memory card’s quick access times can be used for real-time analysis.

Application Scenarios

The Three Siemens 6ES79521AP000AA0 satisfies a wide range of Industrial Ensure broadestpossible operation.

Manufacturing Automation: In the automobile production line, the card serves as a data carrier for real-time robotic control programs as well as sensor information, so that the machines can interact in harmony. for instance it will store weld parameters for quality checks as it is applying motion control algorithms.

Energy Management Systems: Used in grid monitoring stations, this Siemens 6ES79521AP000AA0 stores fault records and load distributions for instant response in case of a power outage or overload.

Back Up and Restore: An insurance policy for pharmaceutical producers – batch recipes and equipment settings can be saved and stored so that production can be quickly resumed after unexpected downtime.
