Considerations Specific to
Safety Modules
Compact 5000 I/O safety modules have additional items of which you must be
aware. Type approval, certification, and suitability for use in safety applications
vary by catalog number.
The following apply to the modules:
• Type-approved and certified for use in safety applications up to and
including SIL 3 per IEC 61508
• Suitable for use in safety applications up to and including SIL CL 3 per
IEC 62061
• Suitable for use in safety applications up to and including Performance
Level e (PLe), category 4 per ISO 13849-1

Safety Modules
IMPORTANT Functional safety certification and performance of Compact 5000 I/O safety
modules requires that the modules operate in conditions at or below the
ambient operating temperature specification.
The probability of a dangerous failure on demand (PFD) and average
frequency of a dangerous failure per hour (PFH) calculations for these
modules are based on the module operating conditions adhering to the
ambient operating temperature specification.
For more information on the maximum ambient operating temperature
specification for Compact 5000 I/O safety modules, see the Compact 5000
I/O Modules and EtherNet/IP Adapter Technical Data, publication
5069-TD001
IMPORTANT Requirements are based on the standards current at the time of certification.
For more information on safety application suitability levels with the
Compact 5000 I/O safety modules, see the following:
