IS200TBTCH1BBB – THERMOCOUPLE TERMINAL BOARD

The IS200TBTCH1BBB is a highly specialized Thermocouple Terminal Board developed by General Electric for the Mark VIe control platform. This board serves as the primary interface between field-installed thermocouples and the turbine control system. It provides a robust and accurate signal path for up to 24 thermocouple inputs, supporting a wide range of thermocouple types such as Type E, J, K, T, and N. Its rugged DIN-rail mountable design allows for easy installation in harsh industrial environments while maintaining high signal integrity.

The board conditions the incoming thermocouple signals and transmits the data to associated I/O modules, such as the IS220PTCCH1A. With cold junction compensation and advanced filtering, the IS200TBTCH1BBB ensures reliable, noise-free temperature monitoring. It plays an essential role in gas and steam turbine applications, where thermal accuracy is critical for efficiency and safety.

This component is part of GE’s modular design philosophy, allowing it to be hot-swapped and easily maintained without disrupting plant operations. Its high accuracy and industrial-grade durability make it a preferred choice in turbine automation systems.
