Mixed Safety Integrity Levels
Such is the flexibility of AADvance that a single controller can support mixed safety
integrity levels; for example, if a system needs SIL3 energize to trip outputs alongside
SIL2 outputs.
The following example shows how a small a viable controller for mixed integrity levels
can be when built from AADvance modules. There are 16 inputs (or 32), two
duplicated 8 channel inputs (or duplicated 16 channel versions), and two groups of 8
outputs (one dual, one simplex) for field devices.
