Description
Overview
The IS200TTURH1B Turbine Protection Input Terminal Board is a GE Mark VIe field‑termination module engineered to interface critical protection and monitoring signals within gas and steam turbine control systems. Designed for high‑reliability applications, the board provides secure wiring, stable signal routing, and robust environmental performance required in modern power generation facilities.
Functional Characteristics
This terminal board supports multiple turbine protection inputs, including sensor, actuator, and trip‑related wiring. The IS200TTURH1B incorporates enhanced circuit pathways and improved signal‑conditioning features to ensure accurate transmission of turbine protection data to the Mark VIe controller.
Key functional features include:
-
High‑integrity terminal points for protection‑related I/O
-
Redundant circuit paths to minimize single‑point failures
-
EMI‑hardened design for noise‑sensitive environments
-
Backward‑compatible layout for integration with earlier Mark VI revisions
-
Modular construction for simplified installation and maintenance
The “H1B” revision includes upgraded components and improved signal isolation, supporting long‑term reliability in harsh turbine enclosures.
