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.

Discrete level used to specify the ability of safety-related parts of con-
trol systems to perform a safety function under foreseeable condi-
tions.
Category Category Classification of the resistance to faults according to EN ISO 13849-1
SIL CL Safety Integrity Level Claim LimitMaximum SIL that can be claimed for a SRECS in relation to architec-
tural constraints and systematic safety integrity.
PFHd
Probability of a dangerous Failure per
HourProbability of a dangerous failure within 1 h
tM Mission time Period of time covering the intended use of an SRP/CS.
PFDProbability Failure per Demand
(Low Demand)Probability of failure, relative to the number of demands.
EN IEC 61508/61511/62061
HFT Hardware Failure ToleranceAbility of a function unit to continue with the execution of a demanded
function despite existing errors or deviations
SIL Safety Integrity Level
Discrete level (one out of a possible four) for Specifying the safety in-
tegrity requirements of the safety functions to be allocated to the E/E/
PE safety-related systems, where safety integrity level 4 has the high-
est level of safety integrity and safety integrity level has the lowest.
SFF Safe Failure FractionFraction of the overall failure rate of a subsystem that does not result
in a dangourus failure.
λSD Failure Rate - safe detected Failure rate of safe detected failures
λSU Failure Rate - safe undetected Failure rate of safe undetected failures
λDD Failure Rate - dangerous detectedRate of dangerous failures that are detected by the diagnostic func-
tions.
