The IS200VRTDH1D is a specialized Resistance Temperature Detector (RTD) Input Terminal Board used within the GE Speedtronic Mark VI turbine control system. This component serves as the physical interface for connecting field-level temperature sensors (RTDs) to the control system. It is designed to receive low-level analog signals from the field, condition them, and pass them to the Mark VI control processors for precise thermal monitoring of critical assets such as gas or steam turbine bearings, exhaust gases, and windings.

Technical Specifications
