FUNCTIONAL DESCRIPTION:
IS200TREGS5B is a Turbine Emergency Trip Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic 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 controller. Up to three trip solenoids can be connected between the TREG and TRPG terminal boards. TREG provides the solenoids' positive side of the dc power, and TRPG provides the negative side. The I/O controller 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. There are several board types as follows:
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.
In redundant TREG applications, it is typical to find one H3B and one H4B board used together. System repairs must be done with the correct board type to maintain the control power separation designed into these systems.
OPERATION:
The VPRO protection module entirely controls TREG, and the only connections to the control modules are the J2 power cable and the trip solenoids. In simplex systems a third cable carries a trip signal from J1 to the TSVO terminal board, providing a servo valve clamp function upon turbine trip. Both TRPG and TREG control the trip solenoids so that either one can remove the power and actuate the hydraulics to close the steam or fuel valves. The nine trip relay coils on TREG are supplied with 28 V dc from the I/O controller. The trip solenoids are supplied with 125 V dc through plug J2 and draw up to 1 A with a 0.1 second L/R time constant.

What is a turbine emergency trip terminal board?
A turbine emergency trip terminal board is a crucial component of a turbine control system. It serves as a central hub for emergency shutdown signals, allowing for rapid and safe turbine shutdown in case of critical events or malfunctions.
How does the emergency trip terminal board work?
The emergency trip terminal board receives signals from various sensors and instruments monitoring the turbine's vital parameters. When a predetermined threshold is exceeded or a critical fault is detected, the board triggers an emergency shutdown sequence, shutting down the turbine to prevent damage or hazards.
What are the key components of an emergency trip terminal board?
Key components typically include input terminals for sensor signals, relay circuits for activating shutdown mechanisms, and interfaces for communication with the turbine control system. Additionally, there may be diagnostic features for testing and troubleshooting.
