Siemens 6ES5910-0AA41 Memory Submodule

This memory submodule provides additional storage for SIMATIC S5 PLC systems. It plugs directly into compatible CPU modules for capacity expansion. Therefore, this component enables larger user programs and more data storage.

Physical Dimensions and Weight Specifications

The Siemens 6ES5910-0AA41 features a compact plastic housing for easy insertion. Its dimensions fit standard S5 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 6ES5910-0AA41 uses a 40-pin edge connector for host module attachment. This interface provides both power and data transfer capabilities. The submodule inserts directly into a dedicated socket on S5 CPUs. Hence, users can install this component without any tools or cables.

Component Count and Memory Architecture

This memory submodule contains one small PCB with EPROM memory chips. The board holds 8 KB of non-volatile storage for user programs. You will also find a write-protect sticker covering the erase window. An onboard lithium battery powers the RAM version during storage periods.

Energy Storage and Power Requirements

The Siemens 6ES5910-0AA41 draws 15 mA from the host module supply. The EPROM version requires no battery for data retention. The module contains no internal capacitors or backup cells. Therefore, it retains all programs 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.
