</dg_ The safe PROFIsafe I/O modules are intended for functional safety in the area of
industrial automation technology, building technology and process technology to
protect man and machine according to Machinery Directive 2006/42/EC.
The PROFIBUS DP and PROFINET IO fieldbus can be used to connect to the
safe PLC. The PROFIsafe I/O modules can be seamlessly integrated into the
existing WAGO-I/O-SYSTEM 750.
Expensive and inflexible cabling are replaced by flexible configurable safety
functions by secure PROFIsafe data transmission via the existing fieldbus system.
It is then possible to optimize the PROFIsafe I/O module to different safety
applications.
The PROFIsafe I/O modules of the WAGO-I/O-SYSTEM 750 can be used to
implement safety applications in accordance with the following standards:
• DIN EN 61508, Part 1 – 7, up to SIL3
• EN ISO 13849, Part 1 – 2 + AC, up to Cat.4/PL e
• DIN EN 62061, up to SIL3
• DIN EN 61511, up to SIL3
