4.6.4 Fail-safe digital modules
Fail-safe digital modules
Fail-safe digital modules are available for implementing safety concepts in the area of
equipment and personnel safety (for example, for emergency stop devices in the operation of
processing machines).
The fail-safe modules ensure safe processing of field information (sensors: e.g., EMERGENCY
OFF buttons, light barriers; actuators, e.g. motor control). You are provided with all the
hardware and software components required for safe processing, according to the required
safety class. The following table shows the available fail-safe modules.
