Product Overview
The IS200VSVOH1B is a high-precision VME Servo Control Board developed by General Electric for the Speedtronic Mark VI and Mark VIe turbine control architectures. This specialized interface card is engineered to manage the complex actuation of electro-hydraulic servo valves, which are fundamental to regulating fuel and steam flow in industrial turbines. By processing Linear Variable Differential Transformer (LVDT) feedback and pulse rate flow inputs, the IS200VSVOH1B ensures millisecond-accurate valve positioning. Its versatile design supports both Simplex and Triple Modular Redundant (TMR) control strategies, providing the high-availability logic required for mission-critical power generation assets and large-scale industrial drives.
Architectural Hardware Configuration
The physical and electronic design of the IS200VSVOH1B is optimized for high-vibration and electromagnetically noisy environments:
-
Servo Control Capacity: Manages up to four independent electro-hydraulic servo channels with dedicated LVDT excitation circuitry.
-
VMEbus Integration: Standardized single-slot VME form factor (2.1 x 18.8 x 26.2 cm) for seamless installation in Mark VI control racks.
-
Onboard Logic Density: Features a component-rich PCB containing over 70 integrated circuits (ICs), including FPGAs for real-time signal processing.
-
Output Management: Integrated with four specialized relays (K1–K4) and ten inductor beads (L1–L10) for superior signal filtering and load switching.
-
Diagnostic Interface: Front-panel monitoring via a J5 connector and a tri-color LED array: Green (RUN), Red (FAIL), and Orange (STATUS).
-
Industrial Protection: The entire board assembly is treated with a professional-grade conformal coating to prevent degradation from moisture and particulates.
-
Connector Topology: Utilizes six primary PCB connectors (P1–P6) to interface with the VME backplane and external terminal boards like the TSVO or DSVO.
Technical Deployment and Field Functionality
As a foundational element of GE’s turbine automation suite, the IS200VSVOH1B is utilized in the following operational contexts:
| Function Category | Application Detail |
| Fuel Regulation | Controlling gas and liquid fuel control valves to maintain precise combustion temperatures. |
| Steam Admission | Modulating steam turbine stop and control valves for speed and load synchronization. |
| Redundant Actuation | Operating in TMR mode to distribute control signals across three independent processors for fault tolerance. |
| Feedback Loop Management | Digitizing analog LVDT position signals to verify actual valve stroke against controller setpoints. |
| Asset Life Extension | Serving as a modern, B-revision replacement for legacy Mark VI systems to improve servo response times. |
