GE DS200FCSAG1A

Product Name:​ Current Sensing Feedback Board
Overview:​ The DS200FCSAG1A is a high-performance current sensing feedback board manufactured by GE, widely used in LS2100 static starter control systems and Mark V Speedtronic platforms. Its core responsibility is to acquire and process low-level analog signals from Current Transformers (CT) and convert them precisely into standard data recognizable by the control unit, thereby achieving efficient closed-loop control.
