　　About IS200TBCIH1BBC

IS200TBCIH1BBC  is a device called a contact terminal board. This is a PCB created for the Mark VI series. The Mark VI series is one of several series of the General Electric (GE) Mark series. These systems are designed to control all operations of gas and steam turbines in industrial environments.

IS200TBCIH1BBC  is a long circuit board with various electronic components on it. Two (2) very large pure black terminal blocks occupy the left half of IS200TBCIH1BBC  . These wiring terminals have forty-eight (48) silver metal terminals. These terminals are identified by a series of numbers from 1 to 48, with twenty-four (24) terminals in each wiring terminal. On the right side of IS200TBCIH1BBC  is a row of long circular capacitors. These capacitors are pure red. Twenty five (25) such capacitors are arranged next to these wiring terminals. The right edge of IS200TBCIH1BBC  has three silver and black socket connector ports. There is a very small integrated circuit labeled with the letter U on the right side of each connector port. The other two (2) white connectors are located in the center of the top of IS200TBCIH1BBC . Both connectors contain three (3) ports that can be used to connect other components to IS200TBCIH1BBC  . There is a row of very long micro resistors on the right side of the PCB center. This line spans almost the entire length of IS200TBCIH1BBC .

　　Function Description

IS200TBCIH1BBC  is a contact input terminal board developed by GE. It is part of the Mark VI series. In the Mark VI system, the terminal board is connected to the VME rack through cables with molded plugs. These cables connect the terminal board to the VCCC or VCRC processor board inside the rack. Both simplex and TMR (Triple Modular Redundancy) systems are fully supported configurations for this connection.

Input capacity and configuration

This board is designed to accommodate 24 dry contact inputs, which are effectively organized and connected to two barrier type terminal blocks. Direct current (DC) power supplies are specifically connected to components for contact excitation, ensuring optimal functionality of contact inputs.

Noise suppression and protection

In order to prevent potential damage caused by power surges and high-frequency noise, a dedicated noise suppression circuit is used for the contact input to enhance its elasticity and reliability in different operating environments.

Integration with Mark VIe system

In the Mark VIe system setup, I/O packs are connected and integrated into TBCI. These packages are fixed on the side mounting bracket to ensure safe installation. Depending on the system configuration, it may be necessary to insert one or two Ethernet cables into the package and download firmware to ensure proper operation.

Power connection and wiring

Power input (JE1 and JE2)

Excitation voltage: The excitation voltage required for operation is transmitted through plugs JE1 and JE2, as shown in the attached figure, to ensure the power input required for contact excitation.

Cable connections for Mark VI or Mark VIe systems

Simplex system connection: Connector JR1 is used for simplex systems to provide the necessary connections for system operation.

Redundant/Triple Modular Redundancy (TMR) system: In TMR settings, all three connectors are used to provide enhanced redundancy. Insert the cable or I/O pack into the corresponding connector, consistent with the specific Mark VI or Mark VIe system and its redundancy requirements.

This comprehensive setup ensures robust integration of TBCI in Mark VI or Mark VIe systems, providing not only optimal contact input capacity but also protection against external interference. Power and cable connections facilitate seamless operation and different levels of redundancy, consistent with the specific configuration settings of the system.

　　Frequently Asked Questions

　　What is IS200TBCIH1BBC ?

It is a contact input terminal board developed by GE under the Mark VI series.

　　What happens if the excitation voltage is below a certain threshold?

If the excitation voltage drops below 40% of the nominal voltage, the I/O pack will trigger a diagnostic alarm. This alarm has been set and locked, indicating a possible issue with the excitation voltage.

　　Does the input related to the terminal board have a testing function?

Yes, diagnostic testing can be initiated to force all inputs connected to this terminal board to enter the open contact (fail safe) state. Input that fails this diagnostic test will also be forced into a fail safe state, triggering a fault to indicate potential issues.

　　What measures will be taken if the input values in TMR settings are inconsistent?

In TMR (Triple Modular Redundancy) configuration, if the input value from the board does not match the TMR voting value obtained from all three boards, a fault will occur, indicating a difference between the input values.
