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.
