GE IS200TREGH1B IS200TREGH1BDB Turbine Emergency Trip Terminal Board

IS200TREGH1BDB Turbine Emergency Trip Terminal Board

The Gas Turbine Emergency Trip (TREG) terminal board 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 overspeed protection, 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 H1A version is not used for new production and is replaced by H1B. 

• H1B is the primary version for 125 V dc applications. Control power from the JX1, JY1, and JZ1 connectors are diode combined to create redundant power on the board for status feedback circuits and powering the economizing relays. Power separation is maintained for the trip relay circuits. 

• H2B is used for 24 V dc applications. All other features are the same as H1B. 

• H3B is a special version of H1B for use in systems with redundant TREG boards. Feedback circuit and economizing relay power is provided only by the JX1 connector. 

• H4B is a special version of H1B for use in systems with redundant TREG boards. Feedback circuit and economizing relay power is provided only by the JY1 connector. 

• H5B is a special version of H1B for use in systems with redundant TREG boards. Feedback circuit and economizing relay power is provided only by the JZ1 connector.

In redundant TREG applications, it is typical to find one H3B and one H4B board used together. It is important that system repairs be done with the correct board type to maintain the control power separation designed into these systems.

Mark VI Systems 

In Mark* VI systems, the VPRO works with the TREG terminal board. Cables with molded plugs connect TREG to the VPRO module. 

Mark VIe Systems 

In Mark VIe systems, TREG is controlled by the PPRO pack on SPRO. The PPRO I/O packs plug into the D-type connectors on SPRO. Cables with molded plugs connect TREG to the SPRO board.
