GE IS200TTURH1C Terminal Board – I/O Signal Termination | Mark VI Turbine Control Platform
Engineering Background
The GE IS200TTURH1C is a dedicated terminal board designed for the GE Mark VI turbine control system — one of the most widely deployed distributed control architectures in gas turbine, steam turbine, and combined-cycle power generation facilities worldwide. The Mark VI platform succeeded the Mark V and introduced triple-redundant (TMR) and simplex (S) control topologies, with the IS200TTURH1C serving as a critical I/O termination point within that architecture.
Product Positioning
Procurement engineers sourcing replacement or spare IS200TTURH1C boards require a supplier who can verify board revision, confirm firmware compatibility, and provide traceable documentation. Konmask.com specializes in exactly this: authenticated GE Mark VI components with full inspection records, enabling maintenance teams to restore turbine control availability with confidence and minimal downtime risk.

Engineering Advantages
- Direct Signal Termination — Eliminates field wiring errors by providing dedicated, labeled terminal points for turbine speed and ultrasonic sensors
- TMR Architecture Compatibility — Supports triple-redundant voting logic, ensuring no single-point failure propagates to turbine trip
- Plug-and-Play Replacement — Board-level swap without re-engineering field wiring; maintains existing cable schedules
- Revision-Controlled BOM — H1C revision designation ensures component-level traceability for regulated plant environments
- Reduced MTTR — Pre-tested boards ship ready for installation, cutting mean time to repair from days to hours
System Architecture & Signal Flow
Within the Mark VI architecture, the IS200TTURH1C terminal board sits between field-mounted turbine sensors (speed pickups, ultrasonic probes) and the VTUR or VCMI control processor cards. Signal flow is as follows:
- Field Sensors → screw terminals on IS200TTURH1C (signal conditioning & surge protection)
- IS200TTURH1C → ribbon/cable interface to VTUR/VCMI processor card
- Processor Card → Mark VI controller backplane (TMR voting or simplex logic)
- Controller Output → turbine protection relay / HMI / SCADA
This board does not perform computation; it provides clean, protected signal paths and physical termination, making its condition and revision integrity critical to system reliability.
Sourcing & Quality Verification
- Visual Inspection — All boards inspected for PCB damage, burnt components, corrosion, and connector integrity before listing
- Revision Verification — Board revision (H1C) confirmed against physical label and GE documentation cross-reference
- Functional Test — Available on request; bench-tested against Mark VI test harness where applicable
- Traceability Documentation — Certificate of conformance, inspection report, and shipping manifest provided with each order
- Anti-Counterfeit Measures — Boards sourced exclusively from decommissioned OEM installations or authorized surplus channels; no gray-market assemblies

Technical FAQ
Q: Is the IS200TTURH1C compatible with Mark VIe?
A: The IS200TTURH1C is designed for the Mark VI platform. Mark VIe uses a different I/O architecture (IONet-based). Cross-compatibility requires engineering review — contact us before ordering for a Mark VIe application.
Q: What is the difference between IS200TTURH1A, H1B, and H1C?
A: Suffix letters denote PCB revision levels reflecting component or layout changes by GE engineering. H1C is the latest known revision in this series. Always match the revision to your existing system BOM where possible.
Q: Can you supply a matched set for a TMR system?
A: Yes. TMR systems require three boards (R, S, T controllers). We can supply matched-revision sets — specify TMR requirement in your RFQ.
Q: Do you provide an IEC/CE test report?
A: We provide our internal inspection report and CoC. OEM GE test certifications are not reissuable for surplus boards; however, our documentation satisfies most plant MRO acceptance procedures.
Q: What is the lead time?
A: In-stock boards ship within 2–3 business days. If sourcing is required, typical lead time is 7–21 business days depending on availability.
