01What certification buys
A SIL rating is documented, audited evidence that a function fails safely at a known probability. That process — not just the hardware — is what you're paying for, and it's why safety functions stay on certified controllers.
02What the Pi does instead
Everything that isn't a safety-instrumented function: monitoring, analytics, vision, optimization and non-safety control. It runs beside the safety system, reading the same world, without ever being in the safety path.
Common questions
The ones we're asked on every first call.
A specific certified product could be, but a general-purpose Pi running Linux isn't, and we won't represent it as one. The responsible design keeps safety on certified gear.
