Function description

The IS200TREAH2ACC is an emergency trip terminal board developed by GE. It is part of the Mark VIe control system. The TREAH1A terminal board is an integral component of the Mark* VIe system and is specifically designed for seamless integration with the PPRO Turbine I/O set. The board’s inputs and outputs satisfy a variety of functions that are critical to turbine operation and safety.

Input and output configuration

The terminal board has a comprehensive input and output range to ensure efficient operation and control:

Customer input terminals: These inputs are facilitated by two 24-point pluggable barrier terminals, providing an organized and accessible interface for customer-specific inputs.

Nine passive pulse rate devices: These devices are distributed in the X/Y/Z section, three in each section, and are responsible for sensing the gears, thus enabling accurate measurement of turbine speed.

Jumper blocks for signal flapping: The jumper blocks play a key role in enabling a set of three-speed inputs to flap to all three PPRO I/O packets, optimizing signal distribution for uniform functionality.

125 V DC TMR Voting Output contacts: These output contacts, labeled H2A and H4A, are key components for system trip activation, ensuring fail-safe measures in the event of an emergency.

Voltage Detection circuits: Four circuits from 24 to 125 V DC are dedicated to monitoring trip strings to improve system safety and reliability by continuously monitoring voltage levels.

Child board connectors: The inclusion of child board connectors allows for optional feature extensions, providing scalability and customization possibilities for additional or enhanced features.

TMR system signal distribution

In Triple modular redundancy (TMR) systems, signal distribution is facilitated through JX1, JY1 and JZ1 DC-62 PPRO connectors, ensuring redundancy and consistent function of multiple components, thereby enhancing system reliability and safety

Install

Wiring configuration: Voltage detection and Circuit breaker relay wiring: The voltage detection circuit and the necessary circuit breaker relay connections are carefully connected to the I/O terminal designated TB1. This setting helps to reliably and efficiently handle voltage monitoring and system trip activation.

Passive pulse rate pickers: The passive pulse rate pickers are connected to the TB2 and play a key role in sensing the toothed wheels and accurately measuring turbine speed.

Terminals and specifications: I/O terminals: Each terminal (TB1 and TB2) is securely secured with two screws to ensure stability and a stable connection. These modules are designed with 24 terminals and are capable of accepting wires up to #12 AWG for robust and efficient wire connections.

Shielded end strips: The shielded end strips are adjacent to each terminal and securely connected to the grounding of the chassis, providing an additional layer of protection against potential interference and ensuring signal integrity and system reliability.

This careful wiring configuration, the connection of specific components to specified terminals, and the shielded end strips ensure the safe and orderly installation of the patch boards.

Frequently Asked Questions

What is IS200TREAH2ACC?

It is an emergency trip terminal board developed by GE under the Mark VIe series.

How do I ensure that the Settings between the TREA board and the PPRO I/O package are properly aligned?

Verify configuration Settings – Configure PPRO for sector or direct speed input and ensure feedback from TREA. The jumper Settings on the TREA and PPRO configurations do not match, triggering an alarm with inconsistent indications.

What happens if the jumper Settings do not match the PPRO configuration?

A mismatch prompts an alarm indicating a difference. This alarm function helps identify and correct inconsistencies for consistent and accurate system operation.
