IS200TRPGH1BDE GE IS200TRPGH1B Turbine Primary Trip Terminal Board
Description:
IS200TRPGH1B is assembly by GE, it is a Turbine Primary Trip Terminal Board. IS200TRPGH1B serves as a critical safety interface inside GE Mark VI and Mark VIe turbine protection systems. It works alongside the TREG board to deliver both primary and emergency trip functions for gas turbine units. 

The IS200TRPGH1B variant supports TMR voting architecture, and it can drive up to three trip solenoids. It offers dual voltage contact ratings: 125 V dc, 1 A and 24 V dc, 3 A for flexible solenoid selection. The board supplies power for as many as eight Geiger-Mueller flame detectors, with each detector running at 335 V dc and drawing 0.5 mA. Its solenoid circuit holds an L/R time constant of 0.1 seconds to guarantee fast shutdown responses. Controlled by VTUR or PTUR turbine protection controllers, it relies on 28 V dc relay coil power. For site wiring, it connects via moulded plug cables or D-type connectors, making field installation straightforward for turbine safety loops.

Key features:
▪ Built for TMR voting trip circuits
▪ Supports three trip solenoid outputs
▪ Dual-rated output contacts: 125 V dc 1 A and 24 V dc 3 A
▪ Compatible with both Mark VI and Mark VIe GE turbine control platforms

Application Value
▪ Gas turbine safety and primary trip protection for power generation plants
▪ Emergency shutdown logic within GE Speedtronic Mark VI control systems
▪ TMR turbine protection configurations for high-reliability power assets
▪ Mark VIe turbine control racks paired with TTURH1C I/O packs
▪ Flame monitoring interfaces for combustion supervision on gas turbines

Expert Recommendation
For the IS200TRPGH1BDE TRPG terminal board, primary turbine trip protection relies on hardware-based 2-out-of-3 relay voting logic, while continuous current, supply voltage and relay contact monitoring supports reliable diagnostics to confirm correct solenoid and relay operation.

FAQ：
1. How to install the IS200TRPGH1BDE board?
(1) Connect the wires for the three trip solenoids directly to the first I/O terminal block.
(2) Connect the wires for the flame detectors (if used) to the second terminal block. Connect the power for the
flame detectors (if used) to the J3, J4, and J5 plug.
(3) Connect the 125 V dc power for the trip solenoids to the J1 plug.
(4) Transfer power to the TREG board using the J2 plug
