Description
Overview
The IS200TH0H1B Terminal Board is a GE Mark VIe field‑wiring interface designed to route and organize I/O signals between turbine instrumentation and the control processor. Built for high‑performance turbine automation systems, this board provides stable connectivity, fault‑tolerant operation, and reliable signal handling in demanding industrial environments.
Functional Characteristics
The terminal board serves as a key interface for connecting sensors, actuators, and auxiliary devices to the Mark VIe controller. It supports both Simplex and Triple Modular Redundant (TMR) architectures, enabling flexible deployment in standard and high‑availability turbine control systems.
Key functional features include:
-
High‑density terminal points for field wiring
-
Support for Simplex and TMR configurations
-
Fast, accurate signal routing to Mark VIe processors
-
Fault‑tolerant design for continuous operation
-
Industrial‑grade components for harsh environments
The IS200TH0H1B is engineered to withstand vibration, temperature extremes, and electrical noise typical of power generation facilities.
