Fail-safe modules

SIEMENS has released the Simatic modules ET 200M 24 F-DI, ET 200M 8 F-DO and ET 200M 10 F-DO, for its Simatic ET 200M I/O station.

The fail-safe modules now meet the requirements of the safety levels SIL 3/Cat4/PL e in mixed operation with standard modules, without the need for a safety protector.

They are equipped with PROFIsafe-Profil 2.0 technology, so they can be used in Profinet networks.

The ET 200M 10 F-DO unit has a 40mm, which is suitable for a cable length of 1000m, offers P/P switching and has a switched current of two amperes per channel.

Each unit includes a “last valid” function which provides the last valid state. The manufacturer claims this function is advantageous in fire and gas applications.
