IS200TRLYH1BGE Mark VI Termination Relay Board | GE Fanuc

Product Overview

The IS200TRLYH1BGE serves as a specialized Termination Relay Board within the General Electric Mark VI Speedtronic control architecture. This 100% Brand New original circuit board manages discrete output signals, acting as the physical interface between the Mark VI I/O packs and field-side inductive loads. It facilitates the switching of solenoid valves, motor starters, and auxiliary turbine equipment. By isolating sensitive control logic from high-current field devices, the IS200TRLYH1BGE ensures deterministic command execution for utility-scale power generation assets.

Technical Specifications

The IS200TRLYH1BGE features a compact, high-density PCB layout designed for seamless integration into Mark VI cabinet assemblies.

Engineering Advantages

• Optimized Galvanic Isolation: The board utilizes high-grade electromagnetic relays to provide physical separation between the 28V DC control bus and external AC/DC field voltages. This isolation prevents field-side electrical surges from propagating back into the central processor, protecting the integrity of the Mark VI core.

• Precision Signal Switching: Integrated snubber circuits and transient voltage suppressors clamp inductive kickback from solenoid coils. This hardware-level protection eliminates contact arcing, significantly extending the operational lifespan of the relays in high-cycle turbine sequencing applications.

• Compact Footprint for High-Density Racks: The 3.5 cm slim profile allows for dense vertical mounting within standard Mark VI termination cabinets. This solves the industrial pain point of limited cabinet space, enabling engineers to expand I/O capacity without requiring additional enclosure footprints.

• Simplified Field Termination: Numbered terminal blocks facilitate rapid and error-free wiring. The board design allows for direct connection of field cables, reducing the need for intermediate terminal strips and minimizing potential points of failure in the signal path.

FAQs

• Is the IS200TRLYH1BGE board a brand new unit?

  Yes. We supply this board as 100% Brand New original factory stock. Each unit remains in its original anti-static shielding and includes the manufacturer's identification marks to guarantee authenticity.

• Can this board replace other TRLY series revisions?

  The "H1BGE" suffix indicates a specific hardware revision level. While many Mark VI boards maintain backward compatibility, you must verify your specific system configuration and terminal board requirements in the GEH-6421 manual to ensure full functional transparency.

• Does this board support Triple Modular Redundant (TMR) systems?

  The IS200TRLYH1BGE typically interfaces with the TMR I/O packs in a Mark VI rack. It accepts voted signals from the R, S, and T controllers, providing the synchronized switching required for safety-critical turbine trip and fuel control loops.

• What mounting hardware is required for installation?

  The board mounts directly to the cabinet's internal standoffs or baseboard. Ensure you use the original GE mounting screws to maintain proper grounding between the PCB ground plane and the cabinet chassis to mitigate electromagnetic interference (EMI).
