GE Fanuc DS200PTCTG1BAA Potential Transformer Current Transformer

Product Overview

The DS200PTCTG1BAA (DS200PTCTG1BAA) is a high-reliability signal conditioner board developed by General Electric for the Mark V Speedtronic Turbine Control System. Functioning as a PTCT (Potential Transformer / Current Transformer) interface, this board is instrumental in the acquisition and normalization of high-voltage and high-current signals from the turbine generator. It translates these raw field inputs into precise, low-level signals that the control processor can safely interpret. Built to sustain the longevity of legacy GE power generation assets, the DS200PTCTG1BAA is a critical component for maintaining accurate monitoring and protection across gas, steam, and wind turbine applications.
