Description
1. Product Title
GE IS200STTCH2ABA‑ Thermocouple Signal Terminal Board for Mark VI Speedtronic System
2. Product Overview
The IS200STTCH2ABA is a field‑wiring terminal board designed for GE Speedtronic Mark VI turbine control systems. This hardware serves as the interface between external thermocouple sensors and main I/O modules, routing temperature signals into the turbine controller while incorporating passive filtering components to suppress high‑frequency electrical noise. IS200STTCH2ABA features terminal blocks for field sensor wiring and dedicated connectors for back‑plane communication with system I/O cards. Ferrite beads, resistors and capacitors built onto the PCB reduce electromagnetic interference induced in plant environments. It stabilizes thermocouple temperature readings, minimizes signal distortion and false alarms, and ensures accurate thermal monitoring for gas and steam turbine critical operating points.
