The J3\/J4\/J5 connectors provide synchronous data exchange for LVDT feedback, excitation routing, and servo current commands. Firmware‑controlled suicide relays rely on flash‑stored logic blocks; compatibility requires matching firmware revisions between VSVO and associated TSVO\/DSVO terminal boards. When the ID device on JR1\/JS1\/JT1 reports a mismatch, the module enters hardware incompatibility fault state, preventing unsafe execution.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does the IS200TSVOH1B support hot‑swap replacement in a powered VME rack?\u003c\/strong\u003e A: No. The processor rack must be powered down before insertion or removal to avoid backplane bus contention and undefined servo output states.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How does the board manage redundant TMR signal distribution?\u003c\/strong\u003e A: JR1, JS1, and JT1 connectors fan out TMR inputs. The board compares sensor values and removes unhealthy LVDT feedback channels when differential limits are exceeded.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What occurs when a servo suicide relay is activated?\u003c\/strong\u003e A: The relay shorts the output to signal common under firmware control.
