SIL qualification / Safety according to IEC 61508
The SIL qualification is only valid for the version of type
07-37A2-***1/**** (APEX).
Important notes and information on the safe handling
of the product.
SIL qualification
During the development of the Ex p control unit, special attention is paid to the
avoidance of systematic errors and the detection and control of random errors.
The most important characteristics and requirements from the point of view of
functional safety according to IEC 61508 are as follows:
Internal monitoring of safety-relevant circuitry parts
In the event of an error, transition of the safety-relevant outputs to a
defined safe state
Determination of the failure probability of the defined safety function
Safe parameter assignment with non-safe operating environment
Re-test
The SIL qualification of components is documented in this manual. All safety-
relevant characteristic data required by the user and the planner for project
planning and operation of the safety-instrumented system are summarized in
this chapter. Further SIL-relevant information is integrated in this manual.
