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.

Benefits
The fail-safe input and output modules S7-1500 provide you with the following advantages:
• High-channel, fail-safe inputs and outputs
• Can be used centrally in SIMATIC S7-1500 and in ET 200MP distributed I/O system
• processing of standard and safety programs
• Uniform engineering for standard and safety automation in the TIA Portal
• Integration of safety-related functions up to SIL 3 according to IEC 61508:2010 or PL e and
category 4 according to ISO 13849-1:2015 or according to EN ISO 13849-1:2015
