IS200TSVOH1BBB  SERVO TERMINAL BOARD

IS200TSVOH2B

Features

• Interface Components: Interfaces with two electro-hydraulic servo valves, which control the operation
• of steam/fuel valves in the system. Valve position is measured using linear variable differential transformers (LVDT), ensuring accurate feedback on valve positions.
• Communication Interfaces: Two cables connect TSVO to the I/O processor (VSVO), utilizing the J5
• plug on the front of VSVO and the J3/4 connectors on the VME rack. These connections
• facilitate the transmission of control signals and feedback data between TSVO and the I/O processor.
• Signal Distribution: Provides Simplex signals through the JR1 connector, ensuring straightforward
• communication for essential functions.For redundancy and fault tolerance, TMR (Triple Modular
• Redundancy) signals are distributed to the JR1, JS1, and JT1 connectors, allowing for resilient operation even in case of component failures.
• External Trip Integration: Plugs JD1 or JD2 serve as connection points for an external trip from the
• protection module, enhancing system safety and reliability. Integration with the protection module
• enables swift response to critical events or abnormal conditions, allowing for timely shutdown or corrective actions.
• Compatibility and Expansion: Designed to seamlessly integrate with existing control systems and
• infrastructure, offering compatibility with standard connectors and communication protocols. The board
• layout and connectors facilitate easy expansion or integration of additional components or functionalities as per system requirements.
