IS200TRPGH2B is a Gas Turbine Primary Tip Terminal Board manufactured and designed by General Electic as partof the Mark Ve Series used in GE Distibuted urbineonto systems. The TRPG in the Mark Ve system is managed by the prmary Lurbine protection controller VTUR or PTUR) and includes nine magnetic relys organizedinto three voting circuits interfacing with three trip solenoids (ETDs. It collaborates wth the TREG to establish primary and emergeny connections to the ETDsControlled by PTuR packs on the TURHIC board. the TRPG supports both simplex and TMR configurations, The TURHIC board features D- Type conectors that ink tothe TRPG and acommodate VO packs. Additionly. the TRPG integrate inputs from eight flame detectors critical for gas urtine operations, and incorporates twodistinct types of boards within the system.

Frequently asked questions：

Q: What is the main function of the GE IS200TRPGH2B board?

A: The board serves as a primary trip interface, managing turbine shutdown signals and connecting trip solenoids, flame detectors, and relay outputs to the control system.

Q: How many trip solenoids can the IS200TRPGH2B support?

A: It supports three trip solenoids, each rated for 125 V DC operation.

Q: How many flame detectors can be connected to this board?

A: The IS200TRPGH2B board supports up to eight flame detector inputs for combustion monitoring.

Q: How many relay outputs are available on the IS200TRPGH2B?

A: The IS200TRPGH2B module provides twelve output relay channels.

Key Functional Features

Simplex Operation: Unlike the H1A/H1B versions (which use three voting relays for TMR applications), the H2B version uses one relay per trip solenoid for simplex applications.

Emergency Trip Integration: The TRPG works in conjunction with the TREG board to form the primary and emergency interfaces to Electrical Trip Devices (ETDs).

Diagnostic Monitoring: The board monitors relay driver control lines and contact states (via a normally closed contact from each relay) to ensure proper functionality and system safety.

Flame Pulse Processing: In the presence of a flame, the detector discharges through the TRPG; the I/O pack then converts this energy into voltage pulses used to determine if carbon buildup is affecting detection.

Board Components

Relays: Contains three magnetic relays, each interfacing with a specific trip solenoid.

Protection Devices: Includes diode bridge rectifiers and Metal Oxide Varistors (MOVs) to act as current suppressors and protect circuitry.

Surface Mount Technology: Utilizes a multilayer PCB populated with SMD components, including polyester vinyl capacitors.
