- TURBINE PRIMARY TRIP TERMINAL BOARD
The IS200TRPGH2B is a Gas Turbine Primary Trip Terminal Board manufactured and desiqned by General Electric as part of the Mark Vle Series used in GE Distributed turbine controI 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).
The I/O pack or board executes the primary trip function by controalling the relays on the TRPG, which operates the main protection solenoids. In TMR applications, three inputs are processed using a two-out-of-three hardware voting circuit implemented via relay ladder logic.

Primary trip control: IS200TRPGH2B works in conjunction with TREG (emergency trip board), with TRPG providing negative DC power and TREG providing positive DC power to drive the trip solenoid.
Flame detection interface: This board integrates 8 input interfaces for Geiger Mueller flame detectors, which is crucial for the safe operation of gas turbines.
Simplex configuration: According to GE's naming convention, H2A and H2B versions are specifically designed for Simplex applications, with each trip solenoid equipped with a relay; In contrast, H1A/H1B is used for Triple Modular Redundancy (TMR) applications.
This board belongs to electrostatic sensitive devices (ESD Sensitive), and an anti-static wristband must be worn during operation to avoid direct contact with the conductive area of the circuit as much as possible.
