This critical interface module facilitates the command and feedback loop between the digital control processors and electro-hydraulic servo valves used to regulate fuel and steam flow. By integrating bi-directional current outputs with LVDT (Linear Variable Differential Transformer) feedback processing, the IS200TSVOH1BDC ensures that turbine valves are positioned with millisecond accuracy. It serves as the physical landing point for field wiring, supporting both Simplex and Triple Modular Redundant (TMR) architectures to meet the highest safety and availability standards in power generation.\u003c\/p\u003e\n\u003ch3\u003eTechnical Characteristics\u003c\/h3\u003e\n\u003cp\u003eThe IS200TSVOH1BDC is distinguished by its sophisticated signal conditioning and flexible coil configuration:\u003c\/p\u003e\n\u003cp\u003eComprehensive Servo Control Channels The board manages four distinct signal types: bi-directional current outputs for servo-valve actuation, LVDT excitation signals, LVDT position feedback, and pulse rate inputs for flow monitoring. This all-in-one interface streamlines the wiring of complex valve assemblies into the DCS.\u003c\/p\u003e\n\u003cp\u003eHigh-Density Feedback Integration Each control loop on the IS200TSVOH1BDC can process up to six LVDT valve position inputs. This allows the system to utilize median or high-select voting logic, ensuring that a single sensor failure does not disrupt the precise regulation of turbine steam or fuel intake.\u003c\/p\u003e\n\u003cp\u003eFlexible Redundancy Support\u003cspan class=\"citation-527 citation-end-527\"\u003eThe hardware is designed for both Simplex and TMR configurations.\u003csup class=\"superscript\"\u003e\u003c\/sup\u003e\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003eIn Simplex mode, it connects via the JR1 plug, while TMR setups utilize JR1, JS1, and JT1 to interface with R, S, and T processors.\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"citation-526 citation-end-526\"\u003eIt supports multi-coil servos, accommodating up to three coils per output channel in redundant configurations.\u003csup class=\"superscript\"\u003e\u003c\/sup\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eExtended Field Connectivity Engineered for large-scale industrial sites, the board supports a maximum two-way cable resistance of 15 ohms.
