GE IS200TSVCH1A – I/O Terminal Board | Mark VI Turbine Control Platform
Engineering Background
The IS200TSVCH1A is a high-density I/O terminal board engineered by GE as part of the 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. Designed to interface field instrumentation signals with the Mark VI controller backplane, this board serves as the critical signal conditioning and termination layer between plant-floor sensors and the control logic engine.
Product Positioning
Targeted at maintenance engineers, reliability teams, and procurement specialists managing aging Mark VI fleets, the IS200TSVCH1A provides a direct OEM-equivalent replacement path without requiring system reconfiguration or firmware updates. Its plug-and-play compatibility with existing Mark VI I/O racks minimizes downtime during planned outages and emergency replacements.

System Architecture & Signal Flow
Within the Mark VI architecture, the IS200TSVCH1A occupies the field-side termination layer. Field instrument cables land on the board’s terminal blocks, where signals are conditioned, filtered, and routed via the backplane ribbon connector to the corresponding I/O processor module (e.g., VCMI, VTUR, VDSP). The board supports both simplex and TMR (Triple Modular Redundant) configurations, making it suitable for both standard and safety-critical turbine protection loops.
Signal flow: Field Instrument → IS200TSVCH1A Terminal Block → Backplane Connector → Mark VI I/O Processor → Control Logic (VCMI/VTUR)

Technical FAQ
Q: Is the IS200TSVCH1A compatible with Mark VIe systems?
A: The IS200TSVCH1A 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.
Q: Can this board be used in a TMR configuration?
A: Yes. The IS200TSVCH1A supports both simplex and TMR rack configurations within the Mark VI system.
Q: What is the lead time for new surplus units?
A: Typically 3–7 business days for in-stock units. Custom sourcing may require 2–4 weeks.
Q: Do you provide installation support?
A: We provide technical documentation and remote guidance. On-site commissioning support can be arranged through our engineering partners.
Q: Is an exchange program available?
A: Yes. Core exchange pricing is available — ship your defective unit and receive a tested replacement at reduced cost.
