GE IS200TREGH2B TERM. BD., TRIP EMER. GAS

الوصف

The GE IS200TREGH2B is a Trip Terminal Board for the GE Mark VI (MKVI) turbine control system. Its main function is to provide a physical interface for critical emergency trip signals, specifically for a gas turbine application.

Function and Purpose ⚙️

The IS200TREGH2B 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, such as fire suppression systems or emergency fuel shutoff valves. 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 IS200TREGH2B 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.
