FUNCTIONAL DESCRIPTION:

IS200TREAH3A is an Aeroderivative Turbine Emergency Trip Terminal Board manufactured and designed by General Electric as part of the Mark 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:

Voltage detection and the breaker relay are connected to I/O terminal block TB1 for the H1 / S1 and H2 / S2 board variations. Wired to TB2 are passive pulse rate pick-ups. Each block is secured with two screws and contains 24 terminals that can accommodate wires up to #12 AWG. Just to the left of each terminal block is a shield termination strip connected to the chassis ground. Voltage detection and the breaker relay are connected to the board's top I/O box terminals for H3 / S3 and H4 / S4 board variations. Wiring is run to the bottom terminals for passive pulse rate pick-ups. A single #12 AWG wire can be inserted into each terminal, which plugs into a header on the TREA board.

CONFIGURATION:

Jumpers JP1 and JP2 control the fanning of the three passive speed pickups in the X section to the PPROs or YPROs in the S and T sections. If you wish to fan the 3 R speed input to the other two TMR sections, place the jumper over the pin pairs.
