IS230TNSVH2A is a Servo Input/Output Module manufactured and designed by General Electric. It is a part of the Mark VIe Control System. The board serves as an interface between the Mark VIe Control System and two electro-hydraulic servo valves responsible for actuating the steam/fuel valves. To measure the position of the valves, the board utilizes linear variable differential transformers (LVDTs). These LVDTs provide accurate and precise feedback on the position of the valves, allowing the control system to make necessary adjustments for optimal performance.
- The board is specifically designed to work with the PSVO I/O pack and the WSVO servo driver.
- The board supports multiple control modes, including simplex, dual, and TMR (Triple Modular Redundant) control. This flexibility allows the system to be configured based on the desired level of redundancy and fault tolerance. Simplex control utilizes one I/O pack with one or two network connections, while dual control employs two I/O packs with one or two network connections. TMR control utilizes three I/O packs, each with one network connection, ensuring the highest level of redundancy and fault tolerance.
- In terms of power supply, the board receives three 28 V DC supplies through plug J28. These power supplies are essential for the operation of the terminal board and the associated servo valves. Additionally, plugs JD1 or JD2 are provided for an external trip from the protection module. These plugs allow for the integration of external trip signals that can trigger specific actions or responses within the system, enhancing the overall safety and protection mechanisms.
- The wiring of sensors and servo valves within the system is facilitated through two I/O terminal blocks. Each terminal block is securely held in place by two screws and provides 24 terminals that can accommodate wiring up to #12 AWG, ensuring compatibility with a range of wire sizes commonly used in industrial applications. These terminal blocks serve as connection points, allowing for the efficient and organized routing of wires.
- Adjacent to each terminal block, there is a shield terminal strip that is connected to the chassis ground. This strip helps to provide grounding and shielding capabilities, minimizing electromagnetic interference and ensuring the integrity of the signal transmission.
- For external trip functionality, the terminal board offers JD1 and JD2 plugs. These plugs are designed to receive external trip wiring, allowing for the integration of external triggers or protective signals. By plugging into the appropriate JD1 or JD2 connector, the system can respond to external events or conditions, enhancing safety and protection features.
- Each servo output has the capability of being configured in a Triple Modular Redundant (TMR) configuration. TMR configuration involves the use of three coils for redundancy and fault tolerance. To select the appropriate size of the coil current, the jumper settings JP1, JP3, and JP5 are used for Servo 1, while JP2, JP4, and JP6 are used for Servo 2. These jumper settings provide flexibility in adjusting the coil current based on the specific requirements and operating conditions of the servo valves.
- The incorporation of the I/O terminal blocks, shield terminal strips, and external trip plugs provides a structured and efficient approach to wiring connections within the system. The availability of TMR configuration and jumper selection for coil currents allows for tailored configuration and optimization of the servo valve outputs. These features contribute to the reliable and precise control of the system, ensuring accurate actuation of the servo valves based on sensor inputs and external triggers.
