The GE IS200TBCIH1C is a Digital Input Terminal Board for the GE Mark VI (MKVI) turbine control system. It’s a key I/O component that provides a physical interface for discrete, or digital, signals coming from field devices.
Function and Purpose ⚙️
The IS200TBCIH1C acts as the crucial link between the turbine’s sensors and the main control processor. It receives on/off signals from contact-based devices like limit switches, pressure switches, and relay contacts. These signals indicate a specific status, such as whether a valve is open or closed, or if an emergency stop button has been pressed. The board provides a secure and organized termination point for the wiring, simplifying installation and maintenance. By isolating the sensitive control electronics from the field wiring, it helps to ensure signal integrity and system protection from electrical noise and surges.
Related Components
The IS200TBCIH1C works in conjunction with other components of the Mark VI system, including:
- Processor Cards: The main CPU of the system, which reads the digitized data from the IS200TBCIH1C.
- I/O Packs: These electronic modules mount directly on the terminal board and contain the active electronics for signal processing and conversion.
- Field Devices: The board connects to a variety of digital sensors, such as limit switches and pressure switches, to acquire the necessary status information.
