The AADvance Safety Controller Chapter 2
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 System Certification The AADvance Controller is certified by independent certifying bodies. Refer
to the certificate for details of the standards included in the certification.
