The VPRO system uses three independent processing paths to evaluate overspeed conditions. Trip solenoid commands are voted using a \u003cstrong\u003e2oo3 scheme\u003c\/strong\u003e, ensuring that no single failure can trigger or inhibit an emergency trip. The Ethernet‑based IONet link maintains deterministic communication between redundant controllers, while \u003cstrong\u003egalvanic isolation\u003c\/strong\u003e across terminal boards prevents fault propagation. This architecture supports \u003cstrong\u003efail‑safe state execution\u003c\/strong\u003e during overspeed or loss‑of‑signal events.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can the IS200VPROH2B be replaced while the turbine is energized?\u003c\/strong\u003e A: No. The protection module interfaces directly with trip solenoids and MPU circuits; the cabinet must be fully de‑energized before removal.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does the VPRO board require calibration after installation?\u003c\/strong\u003e A: No calibration parameters are defined.
