HART transparent

driver

ACT20X-(2)SAI-(2)HAO-S/P

Weidmüller Interface

GmbH CO KG

Detmold, Germany

Systematic Integrity: SC 2 (SIL 2 Capable)

Random Integrity: SIL 2 Capable

Systematic Capability :

The product has met manufacturer design process requirements of Safety

Integrity Level (SIL) 2. These are intended to achieve sufficient integrity against

systematic errors of design by the manufacturer.

A Safety Instrumented Function (SIF) designed with these products must not

be used at a SIL level higher than the statement without “prior use” justification by

end user or diverse technology redundancy in the design.

Random Capability:

The SIL limit imposed by the Architectural Constraints must be met for each

subsystem.

Summary for the HART transparent driver ACT20X-(2)SAI-(2)HAO-S/P:

Configuration:

C1: Single active input and active output

Page 2 of 2

All failure rates are given in FIT=10

-9

SIL Verification:

The Safety Integrity Level (SIL) of an entire Safety Instrumented Function (SIF)

must be verified via a calculation of PFD

AVG

considering redundant architectures,

proof test interval, proof test effectiveness, any automatic diagnostics, average

repair time and the specific failure rates of all products included in the SIF. Each

subsystem must be checked to assure compliance with minimum hardware fault

tolerance (HFT) requirements.
