Technical Specifications

Function and Working Principle

The GE IS200DTCIH1ABB continuously receives low-voltage signals generated by thermocouple sensors installed throughout industrial equipment. Because thermocouples produce extremely small electrical voltages proportional to temperature, the board incorporates high-precision amplification, filtering, cold junction compensation, and analog-to-digital conversion circuits to ensure accurate measurements.

After conditioning the incoming signals, the board transmits high-resolution temperature data to the Mark VI controller, where advanced control algorithms analyze operating conditions in real time. Based on these measurements, the controller regulates fuel flow, cooling systems, excitation systems, and protective functions to maintain safe equipment operation.

The module also supports continuous diagnostic monitoring by detecting abnormal sensor conditions such as open thermocouples, unstable input signals, or temperature excursions. These diagnostic capabilities help maintenance personnel identify problems before equipment damage or unplanned shutdowns occur.
