Siemens 6AV3971-1XD03-0AA0 Memory Submodule

This memory submodule plugs into compatible Siemens HMI panels for storage expansion. It holds project data and configuration files for operator interface applications. Therefore, this component enables quick system recovery and panel replacement.

Physical Dimensions and Weight Specifications

The Siemens 6AV3971-1XD03-0AA0 features a compact plastic housing for easy insertion. Its dimensions match standard HMI submodule slot specifications. The unit weighs approximately 0.02 kg for straightforward handling. Consequently, technicians can carry multiple submodules in a small pouch.

Interface Types and Connection Layout

The Siemens 6AV3971-1XD03-0AA0 uses a 40-pin edge connector for host panel attachment. This interface provides both power and data transfer capabilities. The submodule inserts directly into a dedicated socket on compatible HMIs. Hence, users can install this component without any tools or cables.

Component Count and Memory Architecture

This memory submodule contains one small PCB with flash memory chips. The board holds 2 MB of non-volatile storage for user data. You will also find a controller IC for interface management. An onboard write-protect switch prevents accidental data deletion or overwriting.

Energy Storage and Power Requirements

The Siemens 6AV3971-1XD03-0AA0 draws 25 mA from the host panel supply. The flash version requires no battery for data retention. The submodule contains no internal capacitors or backup cells. Therefore, it retains all data indefinitely without any external power source.

Installation and Operational Use

Users can insert or remove this submodule without powering down the host. A polarized connector prevents reverse insertion into the socket. The submodule includes a recess for a removal tool or flat screwdriver. This design simplifies field upgrades during short maintenance windows.
