The GE IS200TDBTH6A is a Discrete Input/Output Terminal Board for the GE Mark VIe (MKVIe) turbine control system. Its main function is to provide a physical interface for both digital input and output signals from field devices. The “T” in the designation stands for a T-type turbine, and the “TDBT” indicates a specific board configuration.
Function and Purpose ⚙️
The IS200TDBTH6A is a multi-purpose board that acts as the crucial link between the turbine’s digital sensors and actuators and the main control processor. It handles two types of signals:
- Digital Inputs: It receives on/off signals from devices like limit switches and pressure switches, providing status information to the control system.
- Digital Outputs: It receives commands from the control system and sends on/off signals to devices like solenoids, relays, and motor starters to perform a specific action.
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 IS200TDBTH6A works in conjunction with other components of the Mark VIe system, including:
- Processor Cards: The main CPU of the system, which reads the digitized input data and sends digital commands for the outputs.
- 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 and actuators to acquire data and perform control actions.
