GE IS200TBTCH1BBB Thermocouple Terminal Board 330mm x 200mm

The GE IS200TBTCH1BBB is a thermocouple terminal board designed for GE's Mark VI Turbine Control System—an advanced platform for controlling gas, steam, and wind turbine automated drives. Unlike its predecessor, the Mark V, the Mark VI expanded to include wind turbines, representing a significant functional upgrade. As one of the last GE Mark series to integrate patented Speedtronic control technology, the Mark VI remains highly sought after in industrial automation.

Physically, the rectangular IS200TBTCH1BBB features prominent hardware components: two large black terminal blocks, and two silver-black jack connectors. Near the right center, two long rows of small silver capacitors sit alongside a series of solid silver capacitors to their left. The board's center houses two long lines of small blue resistors, with another row of tiny silver capacitors between them.

• Mark VI & Speedtronic Legacy: Tailored for the Mark VI series, supporting gas, steam, and wind turbines—expanding on the Mark V's capabilities and ensuring compatibility with mission-critical turbine control systems.
• Thermocouple-Specific Design: Functions as a dedicated thermocouple terminal board, with two large terminal blocks for secure thermocouple wiring, enabling accurate temperature signal transmission to Mark VI controllers.
• Robust Component Layout: Features clearly labeled jack connectors for easy inter-board integration, plus organized rows of resistors and capacitors that support stable signal processing and reduce wiring complexity.
• Conformal Coating: Equipped with conformal PCB coating, enhancing resistance to moisture, dust, and corrosion—critical for durability in harsh turbine facility environments where temperature and humidity fluctuate.
