The board’s connector layout and isolation‑transformer topology stabilize propagation delay for PT\/CT feedback, ensuring consistent timing for protection‑logic execution. Signal routing is designed to minimize skew across simplex control paths, preserving synchronous operation with the M1 controller.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can the IS200ESYSH3A be replaced while the exciter is energized?\u003c\/strong\u003e A: No. Replacement must occur with the cabinet de‑energized to avoid unintended relay transitions or PT\/CT signal interruption.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does the ESYS board support redundant control?\u003c\/strong\u003e A: The H3 variant operates strictly in simplex mode.
