The GE IS200TICIH2A is an Isolated Contact Input Terminal Board for the GE Mark VI (MKVI) turbine control system. Its main function is to provide a physical interface for discrete, or digital, signals with a high level of electrical isolation.
Function and Purpose ⚙️
The IS200TICIH2A 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. The key feature of this board is its isolated nature. This means the board’s circuitry is designed to electrically separate the sensitive control system electronics from the field wiring. This isolation provides protection against ground loops, electrical noise, and high-voltage transients that can be present in an industrial environment, ensuring a clean and reliable signal.
Related Components 🤝
The IS200TICIH2A 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 IS200TICIH2A.
- 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.
