The IS200TREGH1BDC is an emergency trip terminal board manufactured by General Electric for use in gas turbines
Ve series of machine control system. It consists of two voltage interchanges for bus and generator voltage inputs
Sensors (PTS), and conditional speed signal inputs for I/O packets. In addition, it also has twelve
Relays, each with a silver wire at the top. Relays are white and black, each
Six in a row. Two rows. The terminal board also has a DC-37 pin connector that can be connected to the terminal board
Cable to serve as backup trip relay.

In Mark Vle or Mark VleS control systems, backup protection is provided by SPRO and PPRO/YPRO
Formed by wiring to a relay board. PTUR or YTUR, TTUR and main trip relay terminal board
Provides the main protection, when installed, it is mounted on the DIN rail on a metal plate carrier, can also be carried
It is mounted on a metal plate assembly bolted to the panel.

IS200TREGH1BDC Input and output configuration
The IS200TREGH1BDC terminal board has a comprehensive input and output range to ensure efficient operation and control:
Customer input terminals: These inputs are facilitated by two 24-point pluggable barrier terminals, providing an organized and accessible interface for customer-specific inputs
. Nine passive pulse rate devices: These devices are distributed in the X//Z section, three in each section, with negative meter induction gears, thus enabling accurate measurement of turbine speed.
Jumper blocks for signal flapping: The IS200TREGH1BDC jumper blocks play a key role in enabling a set of three-speed inputs to flap to all three PPRO VO packages, optimizing signal distribution for uniform functionality.
125 VDCTMR voting out contact; These output contacts, labeled H2A and H4A, are critical components for system trip activation, ensuring fail-safe measures in case of emergency.
Voltage Detection circuits: Four circuits from 24 to 125 VDC are dedicated to monitoring trip strings to improve system safety and reliability by continuously monitoring voltage levels.
Child board connectors: The inclusion of child board connectors allows for optional feature extensions, providing scalability and customization possibilities for additional or enhanced features.
