GE DS200TBCAG1A — Product Description

Product Summary

The GE DS200TBCAG1A terminal board provides stable RTD signal termination for Mark V turbine control platforms. Engineers rely on this board because it delivers consistent measurement accuracy even in electrically noisy environments. Moreover, its design supports several RTD types, which allows users to manage mixed sensor installations across turbine bearings, exhaust sections, and auxiliary equipment. The board integrates smoothly into Mark V and EX2000 architectures, therefore simplifying upgrades or replacements in legacy Speedtronic systems.
