The GE IS200TRPGH1A is a Primary Trip Terminal Board for the GE Mark VI (MKVI) turbine control system, specifically designed for a gas turbine. Its main function is to provide a physical interface for critical, high-speed trip signals.
Function and Purpose ⚙️
The IS200TRPGH1A is a vital part of the gas turbine’s safety and protection circuitry. It acts as the bridge between the Mark VI’s control logic and external trip relays. When the control system’s logic determines that a trip condition exists (e.g., overspeed, high vibration, or an emergency stop), it sends a signal to this board. The board then energizes or de-energizes its internal circuitry to open or close the contacts of the connected relays. This action can directly initiate a turbine shutdown or activate other protective equipment. The “Primary Trip” designation indicates its role in handling the most critical and time-sensitive shutdown signals. The “GAS” designation indicates that the board’s configuration and specific signal handling are tailored to the unique requirements of a gas turbine.
Related Components 🤝
The IS200TRPGH1A works in conjunction with other components of the Mark VI system, including:
- Processor Cards: The main CPU of the system, which executes the trip logic.
- I/O Packs: These electronic modules mount directly on the terminal board and contain the active electronics for activating the relays.
- External Trip Relays: The board connects to these external relays, which in turn control the field devices that perform the actual shutdown or protective action.
