PRODUCT INFORMATION
Product Overview
The General Electric IS200TVBAH2A is a Vibration Input Terminal Board designed for Mark VI / Mark VIe control systems. Known by the TVBA acronym, this board interfaces with sensor probes in Speedtronic turbine control assemblies. It provides signal management across gas, steam, and wind turbine automated drive systems.
The assembly integrates two terminal blocks with twenty-four terminals to support fourteen sensor inputs directly. Three removable daughterboards convert positive twenty-eight volt power into negative twenty-eight volt operating power. Individual input lines incorporate dedicated suppression circuits and electromagnetic interference protection.
