Functional Description
IS200SCTTG1A is a static charge transformer developed by GE. It is a part of Mark VI control system. The static charge transformer board serves as an interface module assembly, contributing to the functionality of various components in tandem with other essential boards and equipment. This board is compatible with a standard static charge board and a gating power distribution board.
Integration
- One of the important integration points is with the VATF Voltage Attenuator Card. The VATF card is responsible for reducing input voltage levels to safer ranges that are compatible with downstream control components. This attenuation ensures signal integrity and protects sensitive electronics from voltage spikes or transients that may occur during normal system operation or fault events. By working in tandem, the SCTT and VATF boards maintain consistent voltage control across the system.
- The board also integrates with the SCTL Static Charger Board, which manages the static charge levels within the excitation system. This regulation is crucial for maintaining the electrical balance needed for consistent and reliable gate firing. Uncontrolled charge buildup could otherwise interfere with gate signals or create instability in the power electronics. Together, the SCTT and SCTL boards help manage energy flow and maintain precise control over the excitation process.
- Another essential component in the system is the CPFB Gating Power Distribution Board. This board is responsible for distributing gate power to various components that require it, ensuring that each device receives the correct voltage and current for operation. The SCTT board facilitates signal interfacing and isolation required for this power distribution, playing a supporting role in the broader gating architecture.
- It is mounted using a standard DIN rail (Part Number 238B4952P09), which provides secure and organized installation within the control cabinet. The use of DIN rail mounting enhances modularity and simplifies maintenance or replacement during system servicing. In addition to its core transformation functions, the board also includes three 24 VDC relays, which enable controlled switching within the system. These relays allow for automation and interlocking of signals, improving operational flexibility and reliability.
- To ensure protection against electrical noise and voltage spikes, the board is also equipped with three relay suppressors. These components are installed across the relay coils and serve to suppress the voltage surges generated when a relay is de-energized. This not only helps preserve the relays themselves but also protects nearby control circuitry from electrical interference, enhancing the overall electromagnetic compatibility (EMC) of the system.

Functionality and Contributions
- The board's specific function lies in managing and regulating static charge transformation within the system. It handles the transformation of electrical charges, playing a pivotal role in maintaining proper voltage levels and charge distribution crucial for system stability and performance. Its intricate design and capabilities are specifically tailored to manage these functions effectively.
- The board doesn't operate in isolation; instead, it collaborates closely with associated boards and components within the system. It seamlessly integrates with voltage attenuator cards, static charger boards, gating power distribution boards, and other pertinent components. This collaborative interaction ensures a synergistic operation where each component's functionality complements and enhances the overall performance of the system.
System IONet Communication
- System IONet Communication transmits data between the Control Module and other system modules. Within this framework, the VCMI card located in the Control Module serves as the IONet bus master, directing communication through an Ethernet 10Base2 network connected to slave stations. This communication network acts as a conduit for vital information exchange, ensuring seamless coordination among different system elements.
- One of the distinctive aspects of this communication setup is the implementation of a specialized polling protocol known as Asynchronous Drives Language. This protocol significantly enhances the determinism of the IONet communication compared to traditional Ethernet LANs. By employing this protocol, the system achieves more predictable and deterministic data transmission between the Control Module and the interconnected modules, ultimately boosting the reliability and efficiency of data exchange within the system.
