The DS200DTBBG1A is designed to provide a high-density, easily serviceable I/O interface for turbine control systems. It features two terminal blocks, each with terminals for 95 signal wires, for a total of 190 terminals. The board also includes three 50-pin connectors with bayonet-style connectors, making it easy to connect and disconnect ribbon cables.
The DS200DTBBG1A is typically located in the Mark V system’s QD or C cores, placing the I/O close to the field wiring and minimizing the distance between the control system and the turbine’s digital sensors. This strategic placement ensures efficient signal transmission and reduces the risk of interference or signal degradation.
