Specifications

Description

IS200TREGH1B is a Turbine Emergency Terminal Board manufactured and designed by General Electric and is part of the Mark VI series used in gas turbine control systems. Three emergency trip solenoids are powered by TREG, which is managed by the I/O controller. The TREG and TRPG terminal boards can be wired together to accommodate up to three trip solenoids. TRPG supplies the negative side of the solenoids' dc power, whereas TREG supplies the positive side. The TREG's 12 relays, nine of which form three groups of three to vote inputs controlling the three trip solenoids, are controlled by the I/O controller, which also performs emergency Overspeed protection and emergency stop operations. For 125v dc applications, H1B is the most common variant. To produce redundant power on the board for status feedback circuits and powering the economizing relays, control power from the JX1.JY1.and JZ1 connectors are diode combined. For the trip relay circuits, power isolation is kept. The TRFG terminal board and PpRO are compatible with Mark VI systems. TREG is connected to the PPRO module by cables with molded plugs.

Applications

Thermal power plants (gas turbines/steam turbines): Widely used in GE Frame 6, 7, and 9 series gas turbines. This is the last line of defense ensuring the power plant can shut down instantly in the event of runaway overspeed or loss of lubricating oil pressure.

Nuclear power plants: Serves as a critical safety interlocking component in the turbine control system on the non-nuclear island side.

Large petrochemical drive units: Used for turbine protection driving large compressors.

INSTALLATION

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

OPERATION

The J2 power cable and the trip solenoids are the only connections to the control modules since the I/O controller controls all aspects of TREG. 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.

FEATURES

1. It also supports simplex, dual, and triple-redundant systems with high-speed networked I/O. It is a multilayer PCB with SMD components and connections populated on it. A detachable connector is part of the termination block. TREG terminal boards come in a variety of revisions.

2. The board has a high level of reliability and is, therefore, less prone to damage. However, inappropriate handling and storage can compromise the card's usefulness. As a result, we suggest storing the cards in static-sensitive storage boxes under the prescribed settings.
