The Siemens 6ES5375-0LD31 is a plug-in volatile random-access memory (RAM) submodule engineered for the Siemens Simatic S5 automation system. This module provides 32 KB of high-speed memory capacity, serving as a critical component for real-time program execution, dynamic data register buffering, and active statement sequence management. It is designed to integrate directly into the host processor scan path, allowing for efficient read/write cycles and facilitating rapid modifications to application code without the need for extensive system reboots.
This memory module is widely utilized in industrial environments including petrochemical refineries, power generation facilities, and maritime cargo handling systems where Simatic S5 controllers are deployed to manage complex, time-sensitive automation logic.

No, the 6ES5375-0LD31 is a volatile SRAM module. It requires a constant power supply or a functional backplane battery backup to retain its stored data.
No, hot-swapping is not recommended. Power should be removed from the chassis before installation or extraction to prevent potential data loss or hardware damage.
Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
Finding brand new, original modules is critical for our safety. This team delivers factory-fresh components with full certification. Their commitment to only selling new products makes them our most trusted partner.
We have sourced Honeywell and Schneider parts here for two years. Every shipment arrives well-packaged with original factory seals intact. Clear communication and the best lead times in the industry.
