Turbine Control Relay Output Solution — GE IS200TRLYH1BGF | Mark VIe Series
The GE IS200TRLYH1BGF is a dedicated Termination Relay Board engineered for GE’s Mark VIe turbine control platform. Serving as the critical interface between the Mark VIe controller and field-side relay-driven actuators, this board enables reliable discrete output switching in high-stakes power generation and industrial turbine environments. Procurement engineers sourcing replacement or expansion boards for Mark VIe cabinets will find this module fully compatible with GE Speedtronic architecture.
Where This Product Is Used
The IS200TRLYH1BGF is specified across a broad range of turbine and power plant control applications:
- Gas Turbine Control Panels — Relay output termination for fuel valve, inlet guide vane, and bleed valve actuators in GE Frame 5, 6, 7, and 9 gas turbines.
- Steam Turbine Governor Systems — Discrete relay switching for trip solenoids, lube oil pump starters, and turning gear interlocks.
- Combined Cycle Power Plants (CCPP) — Coordinated relay output management across HRSG bypass dampers, steam bypass valves, and auxiliary systems.
- Compressor Station Automation — Pipeline compressor driver control where relay-based discrete outputs interface with motor control centers (MCCs).
- Offshore Platform Turbine Packages — Harsh-environment relay termination in marine-grade Mark VIe enclosures.
- Industrial Cogeneration Facilities — Relay output boards for synchronization, breaker control, and load-shedding logic.

Why Engineers Specify This Model
- Platform-Native Compatibility — Designed exclusively for the Mark VIe ecosystem; no signal conditioning adapters required.
- Relay Isolation — Galvanically isolated relay contacts protect the controller backplane from field-side voltage transients and inductive load spikes.
- High Contact Reliability — Gold-plated relay contacts ensure low-resistance switching even at low-current signal levels, critical for turbine trip logic.
- Plug-and-Play Replacement — Direct board-for-board swap in existing Mark VIe cabinets with no firmware changes required.
- Proven Field Record — Deployed in thousands of GE turbine installations globally across power utilities, oil & gas, and petrochemical sectors.
- Reduced Downtime Risk — Stocking this board as a critical spare eliminates multi-week OEM lead times during unplanned outages.

Application-Specific FAQ
Q: Is the IS200TRLYH1BGF compatible with Mark VI (non-VIe) systems?
A: The IS200 series is designed for Mark VIe. While some physical similarities exist with Mark VI termination boards, cross-compatibility is not guaranteed. Always verify the target controller revision before ordering.
Q: What is the difference between IS200TRLYH1B and IS200TRLYH1BGF?
A: The suffix “GF” denotes a specific hardware revision incorporating GE engineering change notices. The BGF revision may include updated relay specifications or PCB layout changes. Confirm your cabinet’s required revision with GE documentation GEH-6721.
Q: Can this board be used as a hot spare?
A: Yes. Mark VIe supports TMR (Triple Modular Redundancy) architectures. The IS200TRLYH1BGF can be stocked as a cold spare for rapid swap during planned or unplanned maintenance windows.
Q: What relay contact rating is supported?
A: Standard Form C relay contacts rated for 5 A @ 250 VAC resistive load. Derate appropriately for inductive loads (motor starters, solenoid valves) per GE application guidelines.
Q: Do you provide exchange or repair services?
A: Yes. Konmask.com offers exchange programs where your defective unit is credited against a tested replacement. Contact us for details on our repair and exchange pricing.
