Functional Safety—Safety Integrity Level (SIL) and Performance Level (PL)

Basic Knowledge on Safety Integrity Level (SIL) and Performance Level (PL)

Technical equipment can pose a safety risk so dangerous that people should not be exposed to the equipment. In such cases, the relevant risks must be reduced to meet the need for safe operation. It must be possible to quantify (and measure) risk reduction in order to satisfy this requirement.

These pages give you an overview of the standards and methods that are being applied to achieve safe operation status of plants and machines. Gain insights into the Safety Integrity Level (SIL) as well as the Performance Level (PL) and browse components for your application in our safety product selector.
