Product: IS210TREGH1B GE Trip Din Rail Module

Description

IS210TREGH1B is a Gas Turbine Emergency Trip Terminal Board manufactured and designed by GE as part of the VI Series used in GE Speedtronic Gas Turbine Control Systems.

The Gas Turbine Emergency Trip (TREG) terminal board provides power to three emergency trip solenoids and is controlled by the I/O pack or control board. 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 pack or control board provides emergency overspeed 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. 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.

TREG is entirely controlled by the PPRO / YPRO I/O pack or IS215VPRO board. The connections to the control modules are the J2 power cable and trip solenoids. In simplex systems, a third cable carries a trip signal from J1 to the TSVO terminal board, which provides a servo valve clamp function upon turbine trip.
