If the active processor reports internal diagnostic faults, the secondary unit takes over control bus arbitration within microseconds, preventing signal drift or calculation state loss.\u003c\/p\u003e\n\u003cp\u003eQ: Can the internal power supply circuits switch between AC and DC input configurations dynamically?\u003c\/p\u003e\n\u003cp\u003eA: The chassis power module options must match the specified field distribution. Input options span 100-120 V AC, 220-240 V AC, or 24 V DC systems, and must operate inside the designated input tolerances to prevent triggering the internal 8 A \/ 250 V fuse element.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e19-Inch Chassis Grounding Requirements:\u003c\/strong\u003e Secure the unit firmly onto the metal rails of a standard 19-inch enclosure using paint-piercing washers.
