Siemens 6AV2181-8XP00-0AX0 SIMATIC HMI Memory Card

Siemens 6AV2181-8XP00-0AX0 SIMATIC HMI Memory Card is a 2 GB Secure Digital (SD) memory card designed for Siemens SIMATIC HMI devices that include an SD card slot, supplied as a single card. It provides non-volatile storage for the HMI project file, runtime resources, and logs used by the panel, enabling local storage of configurations and data that persists across power cycles. The card uses a standard SD interface (not USB) and operates on a 3.3 V supply with a maximum tolerance of 3.6 V, drawing about 100 mA during operation. Typical endurance is around 10,000 insertion cycles, making it suitable for routine panel maintenance and field use. The scope of supply for this part number is one memory card, intended for devices with a matching SD slot; it does not include adapters or USB memory functionality. This 6AV2181-8XP00-0AX0 designation is explicitly listed in Siemens data sheets and catalog pages as a 2 GB SD memory card for SIMATIC HMI systems requiring local storage of projects and historical data.
