Functional Description

IS200TBCIH1BBC is a contact input terminal board developed by GE. It is a part of Mark VI series. Within the Mark VI system, the terminal board establishes connections to the VME rack through cables featuring molded plugs. These cables link the terminal board to either the VCCC or VCRC processor board situated within the rack. Both simplex and TMR (Triple Modular Redundant) systems are fully supported configurations for this connection.

Input Capacity and Configuration

The board is designed to accommodate 24 dry contact inputs, effectively organized and wired to two barrier type terminal blocks. Direct current (DC) power is specifically routed into the component for contact excitation purposes, ensuring optimal functionality of the contact inputs.

Noise Suppression and Protection

To safeguard against potential damage caused by surges and high-frequency noise, the contact inputs are fortified with dedicated noise suppression circuitry, enhancing their resilience and reliability in varying operational environments.

Integration with Mark VIe System

In a Mark VIe system setup, the I/O packs are connected and integrated into the TBCI. These packs are affixed to side-mounting brackets for secure installation. Depending on the system's configuration, one or two Ethernet cables may need to be plugged into the pack, potentially requiring firmware downloads to ensure proper functionality.

Power Connection and Cabling

• Power Input (JE1 and JE2)
  • Excitation Voltage: The excitation voltage necessary for operation is routed through plugs JE1 and JE2, as indicated in the provided figure, ensuring the required power input for contact excitation.
• Cabling Connections for Mark VI or Mark VIe Systems
  • Simplex System Connection: Connector JR1 is utilized for a simplex system, providing the necessary connectivity for system operation.
  • Redundant/Triple Modular Redundant (TMR) System: In a TMR setup, all three connectors are employed, offering enhanced redundancy. Cables or I/O packs are plugged into the respective connectors, aligning with the specific Mark VI or Mark VIe system and its redundancy requirements.
  • This comprehensive setup ensures the robust integration of the TBCI within the Mark VI or Mark VIe systems, offering not only optimal contact input capacity but also protection against external interference. The power and cabling connections facilitate seamless operation and varying levels of redundancy, aligning with the system's specific setup configurations.

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 drops below a certain threshold?
If the excitation voltage decreases to less than 40 percent of the nominal voltage, the I/O pack triggers a diagnostic alarm. This alarm is set and latched, signaling a potential issue with the excitation voltage.

Is there test functionality for the inputs associated with the terminal board?
Yes, a diagnostic test can be initiated to force all inputs connected to this terminal board into the open-contact (fail-safe) state. Inputs that fail this diagnostic test are also forced into the fail-safe state, triggering a fault to indicate a potential issue.

What action is taken if the input values don't align in a TMR setup?
In a TMR (Triple Modular Redundant) configuration, if the input value from this board does not match the TMR voted value obtained from all three boards, a fault is generated, indicating a discrepancy between the input values.
