Specifications

Description

IS200TBCIH1BBC IS200TBCIH1B 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.

Applications

Large thermal power plants (gas turbines/steam turbines): Used to monitor hundreds of analog variables such as bearing temperature, oil pressure, and exhaust pressure in the turbines.

Nuclear power plant control systems: Serving as the data acquisition core of the Mark VI system in non-safety-grade control loops.

Combined cycle power plants (CCGT): Widely deployed in the control cabinets of GE Frame 9E/9F class units.

Large petrochemical and smelting plants: Monitoring complex fluid process parameters (flow rate, level, pressure transmitter signals).

Other information

1.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.

2.Noise Suppression and Protection

To safequard 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.

3.Integration with Mark Vle System

In a Mark Vle system setup, the I/O packs are connected and integrated into the TBCl. 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.

Frequently Asked Questions

Q: What is IS200TBCIH1BBC IS200TBCIH1B?

A: IS200TBCIH1BBC IS200TBCIH1B is a contact input terminal board developed by GE as part of the Mark VI series. It provides a connection interface between field contact signals and the Mark VI system’s VME rack.

Q: What happens if the excitation voltage drops below a certain threshold of IS200TBCIH1BBC IS200TBCIH1B?

A: If the excitation voltage decreases to less than 40% of the nominal voltage, the I/O pack triggers a diagnostic alarm. This alarm is latched to indicate a potential problem with the excitation voltage.

Q: Is there test functionality for the inputs associated with the IS200TBCIH1BBC IS200TBCIH1B terminal board?

A: Yes, a diagnostic test can be performed to force all inputs connected to this terminal board into the open-contact (fail-safe) state. Any input failing this test is also forced into the fail-safe state, triggering a fault to indicate a potential issue.

Q: What action is taken if the input values don't align in a TMR setup of IS200TBCIH1BBC IS200TBCIH1B?

A: In a TMR (Triple Modular Redundant) configuration, if an input value from this board does not match the TMR voted value derived from all three boards, a fault is generated, signaling a discrepancy between the input values.
