FUNCTIONAL DESCRIPTION:

IS200TREGH3B is a Gas Turbine Emergency Trip Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Gas Turbine Control Systems. It provides power to three emergency trip solenoids and is controlled by the I/O controller. Up to three trip solenoids can be connected between the TREG and TRPG terminal boards. TREG provides the positive side of the dc power to the solenoids and TRPG provides the negative side. The I/O controller provides emergency over-speed protection, and emergency stop functions, and controls the 12 relays on TREG, nine of which form three groups of three to-vote inputs controlling the three trip solenoids. There are a number of board types as follows:

• The H1B version is utilized in place of the H1A version for new production.
• The main version for 125 V dc applications is H1B. On the board, redundant power is created by bimodally combining control power from the JX1, JY1, and JZ1 connectors to power the economizing relays and status feedback circuits.
• Applications requiring 24 V dc use H2B. Other traits are identical to those of H1B.
• H3B is a modified form of H1B that is used in TREG board redundancy systems. The JX1 connector is the only source of power for the feedback circuit and the cost-saving relay.
• For usage in systems with redundant TREG boards, a special variant of H1B called H4B is available. The JY1 connector is the only source of power for the feedback circuit and the cost-saving relay.
• A modified variant of H1B called H5B is designed for usage in systems with redundant TREG boards. The JZ1 connector is the only source of power for the feedback circuit and the cost-saving relay.

INSTALLATION:

The first I/O terminal block is directly wired to the three trip solenoids, economizing resistors, and emergency stop. The second terminal block can be wired to accommodate up to seven trip interlocks.

OPERATION:

The only interfaces to the control modules are the J2 power wire and the trip solenoids. TREG is totally controlled by the VPRO protection module. When a turbine trips in simplex systems, a third cable transmits a trip signal from J1 to the TSVO terminal board, which operates a servo valve clamp.
