6ES5095-8MD01 SIMATIC S5-95U Central Unit

The Siemens 6ES5095-8MD01 is a compact central processing unit (CPU) from the SIMATIC S5-95U series, specifically configured with a built-in PROFIBUS-DP Slave interface for integration into distributed automation networks. It combines the processor, 24V DC power supply, and I/O in a single compact DIN-rail housing, making it an efficient solution for small to medium control tasks where the controller acts as a DP slave to a higher-level master PLC. The -8MD01 variant is designed for applications where the S5-95U serves as a distributed I/O station controlled by a PROFIBUS-DP master. This architecture is common in legacy installations where a central master (such as an S7-300/400 or a PC-based controller) coordinates multiple S5-95U compact controllers across a PROFIBUS network.
