Description
The GE IS200TBCIH1B appears to be an input terminal circuit board used within the GE Mark VI Series gas turbine control systems. It likely functions to interface with various external devices and sensors, but its specific capabilities depend on the system variation. Here’s a breakdown of the possibilities and how to determine its exact role in your system:
Possible Functions (based on naming convention):
- Input Terminal Board: The “TBCI” in the part number suggests it’s a terminal board for connecting input signals to the Mark VI system.
- Uncertain Specificity (H1B): The “H1B” part of the code might indicate a specific revision or configuration of the board, but publicly available information doesn’t provide a definitive explanation.
Here are two potential functionalities depending on the Mark VI system variation:
- Digital Input Terminal Board (Mark VI): In older Mark VI (not Mark VIe) systems, the IS200TBCIH1B could be a digital input terminal board. This type of board would interface with digital on/off signals from simple contact-based sensors and switches like:
- Pushbuttons for operator control
- Limit switches for position indication
- Pressure switches for safety interlocks
- Vibration switches for fault detection
- Analog or Digital Input Terminal Board (Mark VIe): In Mark VIe systems, the IS200TBCIH1B might be a more versatile input terminal board. It could handle both:
- Digital Inputs: As mentioned above for the Mark VI system.
- Analog Inputs: Sensors that provide a voltage signal proportional to a physical quantity (temperature, pressure, etc.). The board would likely have signal conditioning circuits to convert these analog signals into digital data for the control system.
