About the DS200TCRAG1ACC

The DS200TCRAG1ACC is a printed circuit board (PCB) from General Electric, developed as part of the Mark V Turbine Control System Series. This series is used in the management and control systems of steam, wind, and gas turbine automated drive assemblies. The Mark V Series is considered a legacy series due to its manufacturing discontinuation. The DS200TCRAG1ACC is a Relay Output Board, a revised version of the original DS200TCRAG1, featuring three significant revisions. The Mark V Series is one of the final GE product series to use the patented Speedtronic control system technology introduced with the Mark I in the late 1960s.
