GE IS200TRLYH1BHH – Relay Terminal Board | Mark VI Turbine Control Platform
Engineering Background
The IS200TRLYH1BHH is a relay terminal board engineered by GE as part of the Mark VI turbine control architecture — one of the most widely deployed distributed control platforms in power generation and industrial turbine applications worldwide. This board serves as the critical interface layer between the Mark VI controller logic and field-level relay-driven actuators, enabling reliable discrete output switching in demanding operational environments.
Product Positioning
Designed for procurement engineers and maintenance teams managing GE Mark VI turbine control systems, the IS200TRLYH1BHH provides a direct, form-fit-function replacement or expansion component. It is suited for both OEM-equivalent installations and MRO (Maintenance, Repair & Overhaul) sourcing scenarios where system uptime and signal integrity are non-negotiable.

Engineering Advantages
- Form-Fit-Function Compatibility — Direct replacement for existing IS200TRLYH1BHH installations without system reconfiguration
- Relay Isolation — Provides galvanic isolation between controller logic and field relay loads, protecting upstream electronics
- High Signal Integrity — Engineered to GE Mark VI signal conditioning standards, ensuring deterministic relay switching behavior
- Robust Construction — Industrial-grade PCB and relay components rated for continuous duty in turbine control environments
- Plug-and-Play Integration — Designed for seamless integration within the Mark VI I/O rack architecture
- Reduced Downtime Risk — Stocking this board as a critical spare eliminates extended lead times during unplanned outages
System Architecture & Signal Flow
Within the GE Mark VI architecture, the IS200TRLYH1BHH functions as a terminal board that receives discrete output commands from the Mark VI I/O processor modules. The relay contacts on the board switch field-side loads — such as solenoid valves, motor starters, or alarm annunciators — in response to controller logic states. The board’s relay outputs provide the necessary voltage and current handling capacity to drive industrial field devices while maintaining electrical isolation from the low-voltage controller backplane.
Signal flow: Mark VI Controller → I/O Processor → IS200TRLYH1BHH Terminal Board → Field Relay Loads

Technical FAQ
Q: Is the IS200TRLYH1BHH compatible with all Mark VI variants?
A: The IS200TRLYH1BHH is designed for the GE Mark VI platform. Compatibility with specific Mark VI sub-variants (e.g., Mark VIe) should be confirmed against your system’s I/O configuration. Contact our technical team for cross-reference verification.
Q: What is the difference between H1BHH and other IS200TRLY suffix variants?
A: The suffix designates hardware revision and relay configuration. H1BHH indicates a specific relay contact arrangement and PCB revision. Always match the exact part number to your system’s bill of materials to ensure compatibility.
Q: Can you supply a test report or certificate of conformance?
A: Yes. Test reports and certificates of conformance are available upon request for all units. Please specify your documentation requirements at the time of order.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days. For sourced or refurbished units, lead time is typically 5–15 business days depending on availability. Contact us for real-time stock status.
Q: Do you accept returns or provide warranty?
A: Yes. We offer a 30-day return policy for units in original condition and a 90-day warranty on tested/refurbished units. New units carry manufacturer warranty terms where applicable.
