GE DS200SLCCG3ACC / DS200SLCCG3A 

Overview

The General Electric DS200SLCCG3ACC and DS200SLCCG3A are LAN Communication Cards developed for the GE Mark V Speedtronic turbine control system. These modules act as key communication interfaces, enabling data exchange between the drive control processor and networked system components.

As part of GE’s legacy but widely deployed Mark V platform, these cards remain essential in maintaining and upgrading existing turbine control and drive systems.
