Product Overview

The IS200TREGH1BDC is a vital Trip Primary Gas Termination Card engineered by General Electric for the Mark VIe control platform. This specialized printed circuit board serves as the primary interface for turbine emergency trip logic, specifically managing the electrical signals required to actuate fuel isolation valves. By facilitating the transition between control processor logic and field-side solenoids, this card ensures the rapid and reliable shutdown of gas turbine units during fault conditions. Despite its legacy roots, the H1BDC revision provides high-integrity signal termination and hardware-based voting logic, making it a cornerstone for safety-critical turbine protection within a Distributed Control System (DCS) architecture.

Hardware Configuration and Protective Components

• Isolation Architecture: Equipped with twelve precision square-shaped transformers, organized in dual vertical columns of six, providing galvanic isolation for trip signals.

• Termination Density: Features two heavy-duty black terminal blocks housing 48 silver-plated metal terminals (dual 24-point sets) for secure field wiring.

• Surge Suppression: Integrated with red Metal Oxide Varistors (MOVs) positioned along the PCB perimeter to protect sensitive circuitry from high-voltage transients.

• Logic Interfacing: Includes three dedicated jumper ports—JH1 (3 terminals), J2 (12 terminals), and J1 (2 terminals)—allowing for hardware-level configuration of trip strings.

• Circuit Components: Populated with industrial-grade diodes, resistors, transistors, and integrated circuits designed to meet Mark VIe voltage protection standards.

• Physical Footprint: Compact assembly measuring 2.1 x 18.6 x 26.3 cm with a lightweight mass of 0.22 kg.

Operational Deployment and Industrial Safety Roles
