GE IS200TBAIH1C IS200TBAIH1CED Analog Input Terminal Board

Core Function and System Role

The GE IS200TBAIH1C terminates analog field signals for Mark VI systems. Specifically, this board connects voltage or current transmitters to the controller. Moreover, it provides signal conditioning and filtering for each channel. The IS200TBAIH1CED variant includes conformal coating for harsh industrial environments.

Technical Specifications Overview

This analog input terminal board features sixteen independent input channels. Each channel accepts ±10 Vdc or 4-20 mA signals. Furthermore, the board provides 14-bit resolution for accurate measurements.

Connector Layout and Component Count

The board uses four terminal blocks for field wiring connections. For instance, block TB1 handles channels 1 through 4. Meanwhile, block TB2 manages channels 5 through 8. Blocks TB3 and TB4 handle channels 9 through 16. Two 50-pin D-sub connectors route conditioned signals to the controller. The IS200TBAIH1CED adds a thick conformal coating over all components.

Energy Storage and Signal Integrity

This analog input board includes local capacitance for stable conditioning. Specifically, eight 100 µF capacitors filter the 24 Vdc supply. Therefore, the board provides clean analog readings during power fluctuations. Additionally, onboard LED indicators show each channel’s status. For example, a green LED illuminates when a valid signal is present. An off LED indicates an open circuit or transmitter failure.

Diagnostic Features and Fault Detection

The board continuously checks each channel for open or shorted inputs. Consequently, it detects wiring faults within 100 milliseconds. Moreover, the GE IS200TBAIH1C IS200TBAIH1CED includes overvoltage protection on all inputs. This feature clamps excessive voltages to safe levels. An onboard status register reports all channel health to the main controller.

Maintenance and Hot Replacement

You can replace this analog input board without powering down the turbine. Thus, mean time to repair remains under ten minutes. The board stores no configuration data locally. Therefore, you simply install the replacement and resume normal analog monitoring.

Industrial Applications

This analog input terminal board works inside GE Mark VI control cabinets. For reliable GE analog signal termination, the IS200TBAIH1C and IS200TBAIH1CED deliver exceptional performance. They provide robust signal conditioning for steam and gas turbine pressure, flow, and level transmitters.
