EMERSON KJ2201X1-HA1

Description

This report summarizes the results of the functional safety assessment according to IEC 61508 carried out
on the DeltaV SIS. The following system components are in the assessment scope:
DeltaV SIS Smart Logic Solver
Including:
• DeltaV SIS Simplex Terminal Block
• DeltaV SIS Redundant Terminal Block
KJ2201X1-BA1
KJ2201X1-HA1
KJ2201X1-JA1
DeltaV SIS Aux. ETA Relay Module KJ2231X1-BA1
DeltaV SIS Aux. DTA Relay Module KJ2231X1-BB1
DeltaV SIS Relay Diode Module KJ2231X1-BC1
DeltaV SIS Relay Module KJ2201X1-EA1
DeltaV SIS Voltage Monitor KJ2231X1-EB1
DeltaV SIS End of Line Resistance Module KJ2231X1-EC1
DeltaV SIS RC Compensator Module KJ2231X1-ED1
DeltaV SIS Current Limiter KJ2231X1-EE1
The functional safety assessment was performed to the requirements of IEC 61508:2010, SIL 3. A full IEC
61508 Safety Case was prepared using the exida SafetyCaseDB tool as the primary audit tool. Hardware
process requirements and all associated documentation were reviewed. Environmental test reports were
reviewed. User documentation (safety manual) was also reviewed.
– exida assessed the modifications performed by Fisher Rosemount Systems, Inc. via an audit and
review of modification documents and found that there were no new safety-related changes made
since the last such audit.
These products were previously certified to IEC 61508:2000, SIL 3. This assessment focused on assessing
the product to the differences introduced by IEC 61508:2010. Based on this assessment, it can be
concluded that the Emerson development process meets the requirements of IEC 61508:2010 up to SIL 3.
See section 3 of this document for details on which hardware and software have been included in this
assessment.
The results of the Functional Safety Assessment can be summarized by the following statements:
The DeltaV SIS Smart Logic Solver with its accessories (DeltaV SIS Aux. ETA Relay Module, DeltaV SIS Aux.
DTA Relay Module, DeltaV SIS Relay Diode Module, DeltaV SIS Relay Module, DeltaV SIS Voltage Monitor
Module, DeltaV SIS End of Line Resistance Module, DeltaV SIS RC Compensator Module, and DeltaV SIS
Current Limiter Module) were found to meet the requirements up to SIL 3. Various configurations of
equipment may be used in de-energize to trip or energize to trip modes with limitations, as expressed in
Table 1. The PFDAVG and Architectural Constraint requirements of the standard must be verified for each
element of the Safety Function
