Product Overview

The DS200SDCCG1AEC is a Drive Control Board designed for use within GE's Mark V Series of turbine control systems. As a key controller, this board manages automated drive operations in systems supporting steam, gas, or wind turbines.

Although part of a now legacy product series, the Mark V was among the final GE systems to incorporate the patented Speedtronic control technology—originally launched in the 1960s with the Mark I series. The DS200SDCCG1AEC is an enhanced version of the original DS200SDCCG1 board, distinguished by three significant internal revisions for improved functionality.
