Functional Description
IS200TSVCH1AAA is a servo terminal board developed by GE. It is a part of Mark VIe control system. It is a modular terminal block board designed with a removable barrier-type configuration. This circuit board features two coil outputs, two channels, and two pulse rate inputs, providing a versatile platform for control and measurement applications. The board is equipped to accommodate up to eight Linear Variable Differential Transformers (LVDTs), allowing for precise and accurate position sensing in diverse industrial settings.
Features
- Valve Actuation and LVDT Position Measurement: Interfaces with two electro-hydraulic servo valves responsible for actuating steam/fuel valves. The position of these valves is measured with Linear Variable Differential Transformers (LVDT), ensuring precise and accurate feedback for optimal control in industrial processes.
- Compatibility and Design Specifics: The TSVC is purposefully designed for seamless integration with the PSVO I/O pack and the WSVO servo driver. However, it is explicitly stated that it will not work with the VSVO processor, underscoring the importance of selecting the appropriate components for specific applications within the control system.
- Control Configurations: Supporting simplex, dual, and TMR (Triple Modular Redundancy) control setups, the TSVC offers flexibility in adapting to various operational requirements. This versatility enhances the reliability and fault tolerance of the control system.
- Power Supply: Three 28 V dc supplies enter through plug J28, ensuring that the servo valves receive the necessary power for their operation. This voltage configuration contributes to the efficiency and responsiveness of the control mechanism.
- External Trip Functionality: Plugs JD1 or JD2 are designated for an external trip from the protection module. This external trip functionality adds an extra layer of safety, allowing the system to respond swiftly and effectively to abnormal conditions or potential faults, preventing damage.
Configuration
- In a simplex system configuration, precise settings for servo 1 and servo 2 are achieved through strategic jumper placements. Jumper JP1 is employed for configuring the correct coil current for servo 1, while JP4 is utilized for the configuration of servo 2. This meticulous configuration ensures that each servo operates with optimal coil current, contributing to the efficiency and accuracy of the system.
- In a Triple Modular Redundancy (TMR) system, where redundancy is crucial for reliability, each servo output gains an additional level of complexity. In this setup, every servo output has three coils. The configuration process involves jumper selections using JP 1-3 for servo 1 and JP 4-6 for servo 2. These jumpers enable the selection and adjustment of each coil's current, ensuring precise control in TMR scenarios. It is worth noting that all other configuration adjustments for the servo board are conducted through the toolbox, offering a comprehensive interface for customization and optimization.
- For proper functionality, it is essential to ensure that power is supplied to all three channels. A quick check of the power status involves verifying the positions of three switches: SW1, SW2, and SW3. All these switches must be set to the ON position. Additionally, confirming that the power indicators for channels P28R, S, and T are illuminated provides a visual cue that power is successfully reaching the respective channels. This step guarantees that the servo terminal boards are receiving the necessary power supply, crucial for their effective operation within the control system.
- By adhering to these configuration guidelines, operators can fine-tune the servo terminal boards to meet specific requirements, whether in a simplex or TMR system. Attention to jumper placements and power supply verification ensures optimal performance and reliability in diverse industrial control applications.
Product Attributes
- Power Supply: Operates with a nominal power supply voltage of 24 V DC, which is sourced from three separate supplies: P28R, P28S, and P28T. This ensures a stable and reliable power input, essential for the board’s functionality. The power supply current is 5 A DC, and each input is protected by a Poly-Fuse or a current limit rating set at 1 A DC. This protective mechanism helps prevent overcurrent situations, ensuring the longevity and safe operation of the board.
- LVDT Excitation Output: The board’s LVDT (Linear Variable Differential Transformer) excitation output is designed to operate at a frequency of 3.2 ± 0.2 kHz, providing a precise and consistent signal necessary for accurate position sensing. The excitation voltage is set at 7.00 ± 0.14 V RMS, which ensures a stable and consistent excitation for the LVDTs, contributing to the reliable performance of the position sensing system.
- Pulse Rate Input: For pulse rate input, the board requires a minimum signal of 33 mV peak-to-peak at 2 Hz to ensure accurate measurement. As the frequency increases to 12 kHz, the minimum signal required for proper measurement rises to 827 mV peak-to-peak. This range of signal requirements ensures that the board can accurately measure and respond to a variety of pulse rate inputs, making it suitable for applications with varying signal strengths.
- Magnetic and Active PR Pickup Signals: The magnetic PR pickup signal is capable of generating a robust 150 V peak-to-peak into a 60-ohm load, showcasing its ability to produce substantial output signals. On the other hand, the active PR pickup signal provides versatility with an output range of 5 to 27 V peak-to-peak into a 60-ohm load. This variability in signal strength offers flexibility, accommodating different application needs and ensuring reliable performance across various operational scenarios.
- Fault Detection: Equipped with comprehensive fault detection mechanisms to enhance system reliability and fault tolerance. It can detect if the servo current exceeds set limits or fails to respond, which is critical for maintaining safe and efficient operation. Additionally, the board monitors the regulator feedback signal to ensure it adheres to predefined limits, preventing potential issues that could arise from signal deviations. Furthermore, the board is capable of identifying a failed ID chip, contributing to its overall robust fault-tolerant design and ensuring that any faults are promptly identified and addressed.

Frequently Asked Questions
What is IS200TSVCH1AAA?
It is a servo terminal board developed by GE under the Mark VIe series.
How does the system handle faults in the regulator feedback signal with dual sensors?
In systems with dual sensors for regulator feedback, if one sensor is identified as faulty, it is removed from the feedback calculation, and the system continues to use the data from the operational sensor to maintain functionality.
What happens if any of the fault signals are detected?
Detection of any of the mentioned fault signals triggers a composite diagnostic alarm, labeled L DIAG PSVO. Further details about individual diagnostics can be accessed from the toolbox.
Can the diagnostic signals be individually latched and reset?
Yes, the diagnostic signals can be individually latched. If they return to a healthy state, they can be reset using the RESET DIA signal.
How is the identity of each cable connector on the terminal board ensured?
Each cable connector on the terminal board is equipped with its ID device, which the I/O processor interrogates. This read-only chip contains information such as the terminal board serial number, board type, revision number, and the J connector location. If a mismatch is detected during the interrogation, a hardware incompatibility fault is triggered.
