FUNCTIONAL SAFETY

CHARACTERISTICS

Application note

1 Aim of this document

This application note is a central data source for all

functional safety characteristics of Phoenix Contact safety

products.

It provides values for:

– Machine building according to EN ISO 13849 and

EN IEC 62061

– Process automation according to IEC 61508

Phoenix Contact additionally supports your SISTEMA tool

projects by providing you with a SISTEMA library containing

all components that have already been certified according

to the latest standards.

You can find the current SISTEMA library on our website

under the keyword SISTEMA.

This document also contains the characteristics required to

calculate safety loops in the process industry.
