IS200TRPGH2B is a Gas Turbine Primary Trip Terminal Board manufactured and designed by General Electric as part of the Mark Vle Series used in GE Distributed turbine contro
systems. The TRPG in the Mark Vle system is managed by the primary turbine protection controller (VTUR or PTUR) and includes nine magnetic relays organized into three
voting circuits interfacing with three trip solenoids (ETDs). It collaborates with the TREG to establish primary and emergency connections to the ETDs. Controlled by PTUR packs
on the TTURH1C board, the TRPG supports both Simplex and TMR configurations. The TTURH1C board features D-Type connectors that link to the TRPG and accommodate I/C
packs. Additionally, the TRPG integrates inputs from eight flame detectors, critical for gas turbine operations, and incorporates two distinct types of boards within the system.
The H1A and H1B versions for TMR applications have three voting relays per trip solenoid.
The H2A and H2B versions for simplex applications have one relay per trip solenoid.

Key Features

The "H2B" version is the Simplex (standard) version of the TRPG board, designed for non-redundant applications.
It houses three magnetic relays that interface directly with trip solenoids to manage turbine shutdown procedures.
It works in tandem with the TREG (Trip Relay Emergency Group) board to form a complete emergency and primary interface for ETDs.
125 V DC at 1 A or 24 V DC at 3 A for output contact power.
The board typically operates on a normal power supply of 28 V DC.
In gas turbine applications, this board allows for inputs from eight Geiger-Mueller flame detectors to monitor combustion.
