AC500-S Safety Controller
SIL 3 safety extension to the AC500 platform, engineered in the same toolchain.
Where it fits
Adds certified functional safety to an existing AC500 rack rather than requiring a parallel system. Useful when a plant is retrofitting an emergency shutdown or fire-and-gas function onto control hardware that is otherwise still fit for service.
