Functional Description
IS200STURH1A is a Simplex Terminal Board developed by GE. It is a part of Mark VIe control system. The STUR terminal board stands out as a specialized variant of the turbine terminal board (TTUR), meticulously crafted to cater to specific applications necessitating overspeed protection and primary trip functionalities.
Purpose and Applications
- Mechanical Drives: Ideal for mechanical drives requiring overspeed protection sans synchronizing function.
- Generator Drive Systems: Well-suited for generator drive systems mandating overspeed protection and primary synchronization.
- Other Applications: Suitable for diverse applications necessitating the utilization of the four pulse input circuits of PTUR.
Features
- PTUR Connection: Anchored by a DC-62 pin connector, facilitating the mounting of a single PTUR I/O pack to streamline operations.
- Speed Input: Accommodates up to four speed input signals, empowering comprehensive monitoring and control functionalities.
- Customer Connection Points: Features a user-friendly 48-terminal Euro-style box connector, fostering effortless customer connection for enhanced convenience.
- Trip Solenoid Outputs: Furnishes two trip solenoid outputs, K1 and K2, each fortified by a safety relay (H1, H2), ensuring robust performance and safety compliance.
- Primary Trip Relay Connection: Provides a streamlined interface with a DC-37 pin connector, facilitating seamless integration with primary trip relay (H3, H4) cables.
- Primary Synchronization Support: Accepts two PT inputs and offers two relay outputs (H2, H4) to bolster primary synchronization capabilities, particularly vital for generator systems.
Failure Detection
- External Test Signal: A crucial component for speed input testing, an external test signal is employed to verify the functionality and accuracy of speed input signals. This allows for thorough validation and calibration of the speed input system.
- Redundant Signals: The STUR terminal board incorporates redundant signals to detect failures in normal running speed signals. This redundancy ensures that even in the event of signal failure, the system can seamlessly switch to alternate signals, maintaining operational continuity and reliability.
- External Test Signals: Proper feedback for PT (Primary Trip) inputs necessitates the utilization of external test signals. These signals ensure accurate feedback and functionality of the PT inputs, essential for effective trip functionalities.
- Forcibly Guided Contacts: Depending on the version of STUR being tested, trip relays utilize forcibly guided contacts. This design ensures that the feedback contact accurately represents the position of the power contact. By employing such contacts, the system enhances reliability and precision in trip relay operations.
- Voltage-Based Status Feedback: The breaker closure relay contact logic incorporates voltage-based status feedback mechanisms. This feature enables the system to continuously monitor the status of breaker closure relays and promptly detect any unexpected behavior or anomalies. By providing real-time feedback, this mechanism enhances the overall safety and reliability of the system.

Frequently Asked Questions
What is IS200STURH1A?
It is a Simplex Terminal Board developed by GE under the Mark VIe series.
How does the terminal board detect issues with solenoid relay drivers?
The board continuously monitors feedback from solenoid relay drivers. If there's a problem with the control signal, indicating irregularities or failures, the system generates a fault to prompt investigation and resolution.
What happens if there's a problem with the relay contact position?
The system checks feedback from the relay contact position. If there's an issue with the control signal, signaling a potential malfunction or failure, a fault is created to address the problem promptly.
What triggers a fault related to solenoid power?
Loss of solenoid power prompts the system to create a fault notification. This ensures that any disruption in solenoid power supply is promptly addressed to maintain system integrity.
