Description
Product Overview
Part Number: IS200TBAIH1CCC
Manufacturer: General Electric (GE)
Product Series: Mark VI / Mark VIe Gas & Steam Turbine Control System
Type: Analog Input Terminal Board (TBAI) IS200TBAIH1CCC is the field-side analog input terminal board for GE Mark VIe turbine control system. It acts as the physical wiring interface between field analog transmitters and the IS220PAIC analog I/O pack. It receives field 4-20mA, 1-5V and mV signals from pressure, flow, temperature and position sensors, with built-in signal filtering and transient surge protection to suppress electrical noise. The board uses screw terminals for field wiring and a 37-pin DC connector to link to the I/O pack. Widely used in power plant gas/steam turbine control, critical for safety and governing control loops.

Engineer Notes
- IS200TBAIH1CCC is only a terminal board, it cannot work standalone, must pair with IS220PAIC analog I/O pack.
- Each channel supports configurable analog signal types; set signal range in Mark VIe control software according to field transmitter type.
- Built-in surge and noise filter, but shielded twisted pair instrument cable is still required for field wiring, and cable shield should be single-point grounded.
- Used in turbine safety and governing control loops; wiring must follow GE Mark VIe EMC and grounding specification strictly.
- The suffix H1CCC represents a later hardware revision with improved circuit protection and PCB robustness.
- No hot swap for this terminal board; power off the I/O pack before removing or re-terminating field wires.
- Common replacement part for legacy Mark VIe turbine control retrofit and spare inventory in power plants.
Pre-Shipment Test Protocol
- Visual inspection of PCB, screw terminals, DC37 connector and solder joints
- Continuity test for all 10 input channels
- Insulation resistance test between field channels and logic side
- Input signal path test with 4-20mA / mV signal simulator
- Transient protection component check
- Board labeling and part number verification
- Anti-static & shockproof packaging inspection
Buyer FAQ
Q: Is IS200TBAIH1CCC new original? A: We supply brand new original GE units, 12-month warranty, factory test certificate available on request.
Q: What does TBAI stand for? A: TBAI = Terminal Board Analog Input. It is the field wiring terminal board for Mark VIe analog I/O pack.
Q: What module must IS200TBAIH1CCC pair with? A: It must be used together with IS220PAIC analog I/O pack in Mark VIe rack.
Q: Can I hot swap IS200TBAIH1CCC while the turbine system running? A: Not recommended. You need to shut down the corresponding I/O pack before removing this terminal board.
