SIL 3
SIL 3 architectures:
• SIL 3 de-energize to trip applications.
• SIL 3 energize to action applications when fitted with dual digital
output modules.
• SIL 3 simplex or dual output module architectures
• SIL 3 fail safe I/O fault tolerant processor architecture
• SIL 3 fault tolerant architecture
• SIL 3 fault tolerant simplex, dual and triple input architectures
• SIL 3 dual or triple processor architectures
• SIL 3 high demand applications where the required safe state is greater
than 4 mA, when fitted with dual analogue output modules (A ‘safe
state’ is an output configured to go to a specific value, or configured to
hold last state)

Safety Integrity Level IEC 61508 SIL 2
IEC 61508 SIL 3
(depending on processor and I/O module configuration)
Safety level Degradation 1oo1D, 1oo2D, 2oo3D
(1)
(1) When a controller's processor modules have degraded to 1oo1D, the system must be restored to at least 1oo2D by replacing the
faulty processor module(s) within the MTTR assumed in the PFD calculations; also, unless compensating measures are defined in
the Safety Requirements Specification (SRS) and documented in operating procedures, the application program must be designed
to shut down safety instrumented functions if a module failure due to dangerous fault has not been replaced within the MTTR.
