6ES5095-8MD03 SIMATIC S5-95U Central Unit

The Siemens 6ES5095-8MD03 is a compact central processing unit (CPU) from the SIMATIC S5-95U series, featuring 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 operates as a DP slave to a higher-level master PLC. The -8MD03 is the direct successor to the 6ES5095-8MD02 and represents the final revision of the S5-95U DP Slave variant. It is designed for applications where the S5-95U serves as a distributed I/O station controlled by a PROFIBUS-DP master, a common architecture in legacy installations where a central master coordinates multiple S5-95U compact controllers across a PROFIBUS network.
