SIMATIC Factory Safety

The ET 200M I/O system – modular expansion

The line of safety input and output modules for the ET 200M peripheral I/O station is used for the centralized expansion of the SIMATIC S7-300F or distributed expansion of the safety S7 controllers. An ET 200M station can accommodate both standard and safety input and output modules.

Supported safety buses:

• PROFIBUS via IM 153-2 HF or IM 153 F0 HF
