1.What it is
The 8110 is the physical heart of every TRICONEX Tricon Safety Instrumented System (SIS).
Built for SIL-3, TMR (Triple Modular Redundancy) architecture, it gives you three independent legs of power, data and diagnostics in a single 19-inch rack—no single point of failure, no hot-spare gaps.

Why 8110 still matters
• Hot-swappable I/O – replace any module without tripping the process.
• Triple power buses – keep two on-line while you service the third.
• Field-proven for > 30 years; spares and upgrade CPUs remain available worldwide.
