Functional Description

IS200TBCIH2BBD is a contact input terminal board developed by GE. It is a part of Mark VIe control system. The terminal board is a crucial component designed to accept 24 dry contact inputs, which are wired to two barrier-type terminal blocks. Additionally, DC power is wired to the TBCI to facilitate contact excitation. To ensure reliable operation, the contact inputs are equipped with noise suppression circuitry, offering protection against surges and high-frequency noise disturbances.

Features

• Within the Mark VIe system, the terminal board interfaces seamlessly with the PDIA I/O pack, supporting various operational configurations including simplex, dual, and Triple Modular Redundancy (TMR) applications. Users have the flexibility to plug in one, two, or three PDIAs directly into the TBCI terminal board, depending on their specific application requirements.
• For compatibility and correct mechanical alignment with the PDIA I/O pack, the Mark VIe system necessitates the use of the C version of the board. This ensures proper alignment of connector JT1 with the mechanical support structure of the I/O pack, guaranteeing optimal functionality and reliability within the system.
• By integrating the terminal board into their Mark VIe systems, users can efficiently manage dry contact inputs, benefitting from enhanced noise suppression capabilities and versatile operational configurations tailored to their application needs.

Wiring

• Terminal Connection: Connect the wires for the 24 dry contact inputs directly to two I/O terminal blocks situated on the terminal board. These terminal blocks are securely held down with two screws and are designed to be easily unplugged from the board for maintenance purposes.
• Terminal Block Specifications: Each terminal block features 24 terminals capable of accepting wires of up to 12 AWG gauge. This provides ample space and flexibility for connecting the necessary wires associated with the dry contact inputs.
• Shield Terminal Strip: Adjacent to each terminal block, a shield terminal strip is located and attached to the chassis ground. This strip serves as a dedicated grounding point for shielding purposes, ensuring proper grounding and minimizing the risk of electrical interference or noise affecting the dry contact inputs.

Cabling Connections

• Simplex System: Connect the terminal board to the I/O processor using connector JR1. This connection is sufficient for simplex configurations, where a single processor handles the input signals.
• TMR System: For Triple Modular Redundancy (TMR) systems, connect the TBCI terminal board to the I/O processors using connectors JR1, JS1, and JT1. This setup ensures redundancy and fault tolerance by distributing input signals across multiple processors.
• Connection Variants: Depending on the type of Mark VI or Mark VIe system in use, as well as the desired level of redundancy, cables or I/O packs may need to be plugged in accordingly. Ensure that the cabling connections are made securely and that all connectors are properly seated to maintain reliable communication between the terminal board and the I/O processors.

Frequently Asked Questions

What is IS200TBCIH2BBD?
It is a Contact Input Terminal Board developed by GE under the Mark VIe series.

What happens during the diagnostic test on the terminal board inputs?
During the diagnostic test, all inputs associated with the terminal board are forced into the open contact (fail-safe) state. Any input that fails this test is forced into the fail-safe state, resulting in the creation of a fault.

What occurs if the input from the terminal board does not match the TMR voted value from all three boards?
If the input from the terminal board does not match the Triple Modular Redundancy (TMR) voted value from all three boards, a fault is generated.

How are terminal board connectors identified and verified?
Each terminal board connector is equipped with its own ID device, which is interrogated by the I/O pack/board. This ID device contains information such as the board serial number, type, revision number, and connector location (JR1/JS1/JT1). If a mismatch is detected during the reading process, a hardware incompatibility fault is triggered.
