The module is engineered for hot-swapping within the Mark VIe I\/O rack. Ensure the turbine control application is set to a safe state before module extraction to prevent unexpected actuation of connected field devices.\u003c\/p\u003e\n\u003cp\u003eQ: How does the dual power input function?\u003c\/p\u003e\n\u003cp\u003eA: The module accepts two independent 28 V DC power sources with automatic failover logic. This redundancy ensures continued output operation in the event of a single power supply failure, maintaining the availability of critical turbine protection loops.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Seat the module into the designated Mark VIe I\/O rack slot.
