Gas Turbine Control Solution – GE IS200TBCIS2C | Mark VI Series
Where This Product Is Used
The GE IS200TBCIS2C Contact Input Termination Board is a mission-critical interface component deployed in GE Mark VI and Mark VIe turbine control systems across the globe. You will find this board at the heart of:
- Gas turbine power plants – managing discrete contact signals from flame detectors, vibration switches, lube oil pressure switches, and emergency shutdown relays
- Combined-cycle (CCGT) facilities – where reliable contact input scanning is essential for coordinating steam and gas turbine sequencing
- Industrial compressor stations – interfacing field-level dry contact devices to the Mark VI controller rack
- Offshore oil & gas platforms – providing robust signal termination in harsh, vibration-prone environments
- Cogeneration and district energy plants – ensuring safe, deterministic contact state monitoring for protection logic
When a termination board fails or is unavailable, field contact signals — from emergency stop buttons, limit switches, and protective relays — cannot reach the controller. The result is forced turbine shutdown, loss of protection visibility, and costly unplanned outages. The IS200TBCIS2C eliminates that risk by providing a dedicated, high-integrity contact input interface designed specifically for the Mark VI architecture.

Why Engineers Specify This Model
- Direct OEM form-fit-function replacement – no firmware changes or re-engineering required when swapping into an existing Mark VI rack
- Deterministic scan cycle – contact states are read and transmitted to the VCMI/TCQA controller cards with predictable, low-latency timing critical for turbine protection
- Robust field wiring interface – screw-terminal or connector design accommodates standard field cable gauges used in power plant I&C panels
- Isolation architecture – optical or relay isolation protects controller backplane from field-side transients and ground faults
- Long service life – designed to GE’s industrial-grade reliability standards for continuous 24/7 operation in high-temperature turbine enclosures
- Proven global installed base – the IS200TBCIS2C is specified in hundreds of Mark VI installations across North America, Europe, Middle East, and Asia-Pacific

Application-Specific FAQ
Q: Is the IS200TBCIS2C compatible with both Mark VI and Mark VIe systems?
A: Yes. The IS200TBCIS2C is designed for the GE Mark VI platform and is also compatible with Mark VIe systems that use the same termination board form factor. Always verify your rack configuration with your OEM documentation before ordering.
Q: Can this board be used as a direct replacement without reprogramming the controller?
A: In most cases, yes. As a termination board, the IS200TBCIS2C is a passive interface — it does not contain firmware. Replacement is typically plug-and-play within the same Mark VI rack slot.
Q: Do you supply new or refurbished units?
A: Konmask.com supplies both new surplus (unused, original packaging) and tested refurbished units. Unit condition is clearly stated in your quotation.
Q: What is the lead time for the IS200TBCIS2C?
A: In-stock units ship within 2–3 business days. For out-of-stock items, typical lead time is 2–4 weeks depending on global sourcing availability.
Q: Can you supply a full Mark VI spare parts kit?
A: Yes. Konmask.com specializes in complete Mark VI BOM sourcing. Contact us with your full parts list for a consolidated quotation.
