Overview
The GE IS200TRTDH1D is an RTD Input Terminal Board designed for the Mark VI Speedtronic turbine control system. It collects temperature data from field devices and transmits accurate readings to the controller. The board supports up to 16 three-wire RTD inputs and ensures high reliability in heavy-duty gas and steam turbine applications. Its noise suppression circuitry protects signals from high-frequency interference and surge, maintaining measurement integrity over long cable runs. Designed for simplex configurations, IS200TRTDH1D offers easy maintenance with removable terminal strips.
