Product Description

Overview
The GE IS200TRTDH1CCC is a high-precision Resistance Temperature Detector (RTD) terminal board engineered for use in Mark VI and Mark VIe Speedtronic control systems. Designed for turbine and process monitoring applications, it converts resistance signals from field RTD sensors into accurate digital inputs for control processors. The CCC revision features a conformal coating, enhancing durability in environments with moisture, dust, and corrosive gases.
