SIEMENS SIMATIC S5 6ES5103-8MA03 – CPU 103 for S5-100U PLC Systems
The Siemens SIMATIC S5 6ES5103-8MA03 is a CPU 103 central processing unit designed for the SIMATIC S5-100U programmable logic controller system. This module functions as the main processor in compact automation solutions, handling logic execution, communication, and data management for small to medium industrial applications.
The CPU 103 is a compact, standalone unit equipped with essential processing features for controlling digital processes. It supports modular system expansion through additional I/O modules, allowing users to scale the controller to meet specific application demands.
This processor features 20 KB of user memory and is powered by a 24V DC supply. It includes a single 20 mA current loop (TTY) interface for connecting programming devices, operator panels, or network components using SINEC L1. Although the unit has no built-in I/O, it is designed to work seamlessly with external I/O modules from the S5-100U series.
The CPU supports STEP 5 programming software and can be programmed using STL (Statement List), LAD (Ladder Diagram), or FBD (Function Block Diagram). Built-in diagnostic LEDs provide clear status and fault indication, simplifying commissioning and maintenance.
