GE IS200TBCBH1A IS200TBCBH1AAA RTD Module

The GE IS200TBCBH1A and GE IS200TBCBH1AAA serve as precise RTD termination modules for turbine control. These units belong to the Mark VI series from General Electric. They directly connect resistance temperature detectors to the main control system. Consequently, these modules provide accurate temperature readings for critical turbine components.

Functional Design and Temperature Sensing

The GE IS200TBCBH1AAA connects directly to the analog input backplane. It accepts low-level resistance signals from PT100 sensors. Then, this module converts these signals into usable digital values. Each channel includes a precision current source for excitation. Therefore, the IS200TBCBH1A eliminates lead resistance errors in long cable runs.

Installation and Compatibility Notes

You must verify sensor wiring before connecting to this termination module. The GE IS200TBCBH1A fits exclusively into Mark VI series turbine cabinets. Always replace faulty units with identical GE board revisions. Additionally, match each channel to the correct RTD type and range. This practice ensures accurate temperature monitoring across all turbine bearings.
