This company has improved the performance and increased the functionality of the fail-safe modules for its modular Simatic ET 200M I/O station. The new ET 200M modules (24F-DI, 8 F-DO and 10 F-DO) are now able to meet the requirements of the safety levels SIL3 (Cat. 4/PLe) in mixed operation with standard modules, without the need of a safety protector. The new modules are equipped with PROFIsafe Profil 2.0. enabling them to be used in Profinet networks. The narrow (40 mm) design of the ET 200M 10 F-DO is now suitable for a cable length of 1,000 m, offering P/P switching (current sourcing) and has a switched current of two amplifiers per channel. — Siemens AG, Industry Automation Division, Nuremberg, Germany
