Essential details：IS200TREAS1AED IS200TREAS1A Aeroderivative Turbine Emergency Trip Terminal Board
Product 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.

APPLICATION
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.
Superiority products IS200TREAS1AED IS200TREAS1A Aeroderivative Turbine Emergency Trip Terminal Board
- 24-Point Pluggable Barrier Terminal Blocks
- Jumper Blocks: Jumper blocks are provided to enable the distribution of one set of three speed inputs across all three PPRO or YPRO I/O packs. This feature ensures consistent and accurate speed input across the entire control system, enhancing the reliability of turbine speed measurements.
- Power and Trip Output Configurations
- TMR Voted Output Contacts: The board includes two TMR (Triple Modular Redundant) voted output contacts, which are crucial for initiating an emergency trip. These contacts are available in the following configurations:
- 24 V DC Outputs: Configurations H1A/S1A and H3A/S3A.
- 125 V DC Outputs: Configurations H2A/S2A and H4A/S4A.
- Voltage Detection Circuits: The board is equipped with four voltage detection circuits, which operate within a range of 24-125 V DC. These circuits continuously monitor the trip string, ensuring that any anomalies or faults in the trip circuitry are promptly detected and addressed.
- Daughterboard Connectors: The terminal board includes connectors for daughterboards, allowing for optional feature expansion. This modularity ensures that the board can be easily upgraded or customized to meet specific operational requirements or to incorporate new technologies as they become available.
