The General Electric IS200TRPGH2B is a Primary Trip Terminal Board designed for the Mark VI Speedtronic control system. This board functions as a simplex interface, providing essential control and monitoring for turbine protection solenoids. It is engineered to operate in conjunction with the TREG board to manage the primary and emergency sides of the interface to the Emergency Trip Devices (ETDs).

Features

  • Simplex version of the TRPG terminal board series.
  • Supports inputs from up to eight Geiger-Mueller flame detectors, suitable for gas turbine applications.
  • Integrated diagnostic monitoring for relay coil current and contact state feedback.
  • Tracks supply voltages (125 V DC) to ensure trip actuation power availability.
  • Pulse frequency counting for flame detection (40 ms interval).
  • Conformal PCB coating for enhanced environmental protection.

Applications

  • Turbine machinery condition monitoring and fault prediction in the power industry.
  • Rotating equipment monitoring in oil extraction and pipeline compressor stations.
  • Control of large-scale turbine-driven compression units in petrochemical plants.
  • Redundant fault-tolerant control in blower systems for the metallurgical industry.

Installation Guidelines

  • Ensure the control system is powered down before installing or removing the module from the rack.
  • Handle the PCB by the edges to prevent electrostatic discharge (ESD) damage to sensitive components.
  • Verify that the board is securely seated in the designated Mark VI slot to ensure proper backplane communication.
  • Ensure all terminal block connections are tightened to the specified torque to prevent intermittent signal loss.
  • Maintain proper ventilation within the cabinet to prevent overheating of the terminal board components.

FAQ

What is the primary function of the IS200TRPGH2B?

The IS200TRPGH2B is a Primary Trip Terminal Board that manages the interface between the Mark VI control system and turbine protection solenoids, providing both control and diagnostic feedback.

How does this board handle flame detection?

It supports up to eight Geiger-Mueller flame detectors, measuring the frequency of incoming 0–5 V pulses over a 40 ms interval to determine flame status.

What is the difference between the H1 and H2 versions?

The H1 versions are typically used in Triple Modular Redundant (TMR) applications with voting logic, while the H2 versions, such as the IS200TRPGH2B, are designed for simplex applications.
