Siemens 6ES5375-0LA71 Memory Submodule

This memory submodule plugs into compatible SIMATIC S5 modules for storage expansion. It holds user programs or configuration data for automation tasks. Therefore, this component enables quick capacity upgrades without replacing entire modules.

Physical Dimensions and Weight Specifications

The Siemens 6ES5375-0LA71 features a compact plastic housing for easy insertion. Its dimensions match 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 6ES5375-0LA71 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 boards. 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 or RAM chips. The board holds 4 KB of non-volatile storage for user data. 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 6ES5375-0LA71 draws 15 mA from the host module supply. The EPROM version requires no battery for data retention. The RAM version uses a small lithium coin cell for backup. Therefore, users should select the appropriate type for their application needs.

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.
