GE IS200STCIH2A – Turbine Control Terminal Board | Mark VI / Mark VIe Platform
Engineering Background
The IS200STCIH2A is a field-proven terminal board designed for GE’s Mark VI and Mark VIe turbine control platforms — the industry-standard distributed control architecture deployed across gas turbines, steam turbines, and combined-cycle power generation units worldwide. This board serves as the critical I/O interface layer between field instrumentation and the Mark VI controller core, enabling reliable signal conditioning, termination, and routing in demanding industrial environments.
Product Positioning
Sourced from decommissioned OEM installations and certified surplus channels, the IS200STCIH2A at Konmask.com is targeted at maintenance engineers, OEM integrators, and procurement teams requiring a drop-in replacement or spare-parts inventory buffer for operational Mark VI / Mark VIe systems. Each unit is inspected prior to dispatch and ships with full traceability documentation.

- Redundancy Support — Compatible with TMR (Triple Modular Redundancy) and dual-redundant Mark VI configurations
- Long Service Life — Industrial-grade PCB construction rated for continuous operation in Class 1 control room environments
- Immediate Availability — Surplus stock held in climate-controlled warehouse; same-day or next-day dispatch on confirmed orders
System Architecture & Signal Flow
Within the Mark VI architecture, the IS200STCIH2A terminal board sits at the field-side boundary of the I/O subsystem. Field wiring from sensors, actuators, and transmitters terminates directly on this board. Signals are then routed via I/O pack connectors to the corresponding Mark VI I/O module (e.g., VCMI, VTUR, VGEN packs), which performs A/D conversion, signal conditioning, and communication to the Mark VI controller core (VCCC / VCRC) over the IONet or IONET redundant network.
This architecture ensures that the terminal board itself is a passive, high-reliability component — field-replaceable without controller downtime in most configurations, provided proper isolation procedures are followed per GE GEH-6721 maintenance documentation.

Technical FAQ
Q: Is the IS200STCIH2A compatible with both Mark VI and Mark VIe systems?
A: Yes. The terminal board is mechanically and electrically compatible with both Mark VI and Mark VIe I/O pack configurations. Verify the specific I/O pack revision (H1A, H2A, etc.) matches your cabinet’s wiring harness before installation.
Q: Does this board require any firmware programming or configuration?
A: No. The IS200STCIH2A is a passive termination board with no onboard firmware. It requires no programming and is ready to install upon receipt.
Q: What is the warranty on surplus units?
A: Konmask provides a 90-day functional warranty on all inspected surplus units. New-in-box units carry the original OEM warranty terms where applicable.
Q: Can you provide a Certificate of Conformance (CoC) or material test report?
A: A Konmask inspection certificate is provided with every unit. OEM CoC availability depends on source documentation; please inquire at time of order.
Q: What are the payment terms for international B2B orders?
A: Standard terms are T/T (wire transfer) against proforma invoice. Credit terms available for established accounts. Contact us to discuss your procurement requirements.
