FUNCTIONAL DESCRIPTION:

IS200TREAS1A is an Aeroderivative Turbine Emergency Trip Terminal Board manufactured and designed by General Electric as part of the VIe Series used in GE Distributed Gas Turbine Control Systems. The Aeroderivative Turbine Emergency Trip (TREA) terminal board works with PPRO and YPRO turbine I/O packs as part of the Mark VIe or Mark VIeS system respectively. The inputs and outputs are as follows:

• Customer input terminals are provided through two 24-point pluggable barrier terminal blocks (H1A or S1A, H2A or S1A) or 48 pluggable Euro-style box terminals (H3A or S3A, H4A or S4A).
• Nine passive pulse rate devices (three per X/Y/Z section) sense a toothed wheel to measure the turbine speed.
• Jumper blocks that enable fanning of one set of three-speed inputs to all three PPRO or YPRO I/O packs.
• Two 24 V dc (H1A / S1A, H3A / S3A) or 125 V dc (H2A / S2A, H4A / S4A) TMR voted output contacts to trip the system.
• Four 24-125 V dc voltage detection circuits for monitoring trip string.
• Daughterboard connectors for optional feature expansion. For TMR systems, signals fan out to the JX1, JY1, and JZ1 DC-62 PPRO or YPRO connectors.

INSTALLATION:

For H1 / S1 and H2 / S2 board variants, voltage detection, and the breaker relay are wired to the I/O terminal blocks TB1. Passive pulse rate pick-ups are wired to TB2. Each block is held down with two screws and has 24 terminals accepting up to #12 AWG wires. A shield termination strip attached to the chassis ground is located immediately to the left of each terminal block. For H3 / S3 and H4 / S4 board variants, voltage detection and the breaker relay are wired to the I/O box terminals at the top of the board. Passive pulse rate pick-ups are wired to the lower terminals. All terminals plug into a header on the TREA board and accept up to a single #12 AWG wire.

FREQUENTLY ASKED QUESTIONS:

What are the common signals processed by the Emergency Trip Terminal Board?

Common signals include those related to overspeed, excessive temperature, high vibration, fire detection, and manual emergency trip commands.

How does the Emergency Trip Terminal Board interact with the turbine's control system?

The terminal board interfaces with the turbine’s control system, usually a PLC (Programmable Logic Controller) or a DCS (Distributed Control System), which processes the trip signals and initiates the shutdown.

How quickly does the Emergency Trip Terminal Board respond to a fault?

The terminal board is designed to respond almost instantaneously to any fault condition. The response time is typically within milliseconds, ensuring the turbine is shut down as quickly as possible to prevent damage.
