Turbine Control I/O Solution — GE IS200TRROH1B | IS200 Series
Where This Product Is Used
The GE IS200TRROH1B is an Input Terminal Board designed for use within General Electric’s Mark VI Turbine Control System. It serves as the physical I/O interface layer between field wiring and the Mark VI controller, and is deployed in the following industrial environments:
- Gas turbine power generation plants — interfacing thermocouple, RTD, and discrete signal inputs from turbine skids
- Steam turbine control systems — providing reliable terminal connectivity for temperature and vibration monitoring loops
- Combined-cycle power plants (CCPP) — used in both gas and steam turbine control cabinets within the same facility
- Compressor stations and pipeline control — where Mark VI platforms manage rotating equipment protection and sequencing
- Offshore and onshore oil & gas facilities — in hazardous-area control rooms requiring certified, OEM-grade terminal boards
- Industrial cogeneration systems — integrating field I/O from heat recovery steam generators (HRSGs)
Engineers specify this board when replacing degraded terminal boards in existing Mark VI cabinets, or when expanding I/O capacity in turbine control upgrades.

Why Engineers Specify This Model
- OEM-matched revision — The H1B revision ensures pin-for-pin compatibility with existing Mark VI I/O racks without firmware or wiring changes.
- Drop-in replacement — Eliminates re-engineering time during unplanned outages; field technicians can swap and restore within a single maintenance window.
- Signal integrity — Precision terminal blocks maintain low-resistance connections critical for thermocouple accuracy in turbine temperature monitoring.
- Proven field reliability — IS200-series boards are deployed across thousands of GE turbine installations globally, with a well-documented maintenance history.
- Reduced downtime risk — Stocking a spare IS200TRROH1B eliminates lead-time exposure during critical turbine outages where every hour of downtime carries significant cost.

Application-Specific FAQ
Q: Is the IS200TRROH1B compatible with both Mark VI and Mark VIe systems?
A: The IS200TRROH1B is primarily designed for the Mark VI platform. Mark VIe uses a different I/O architecture (IONET-based). Please confirm your controller generation before ordering.
Q: Can I use a refurbished board in a safety-critical application?
A: Refurbished boards that pass functional testing are used in non-SIL-rated loops by many operators. For SIL-rated safety loops, consult your site’s functional safety engineer and GE’s certification documentation.
Q: What is the typical lead time?
A: In-stock units ship within 2–3 business days. For out-of-stock items, sourcing lead time is typically 2–4 weeks. Contact us for real-time availability.
Q: Do you provide a warranty?
A: Yes. We offer a 90-day warranty on tested units covering functional defects. New OEM units carry the manufacturer’s standard warranty terms.
Q: Can you supply multiple units for a plant-wide spare parts program?
A: Yes. Konmask supports bulk B2B procurement. Contact us for volume pricing and consignment stocking arrangements.
