GE DS200LDCCH1AGA LAN & Drive Control Board Mark V Turbine Control

GE DS200LDCCH1AGA is a LAN and drive control processor board built for GE Mark V Speedtronic turbine control system. It integrates multiple microprocessors to handle drive control logic, motor regulation and LAN communication, serving as a key data bridge between the main controller, I/O boards and HMI in gas and steam turbine control cabinets.

This board supports HDLC communication protocol for reliable real-time data exchange within the Mark V rack. It provides self-diagnostic functions to monitor board status and communication faults. It is widely used as spare replacement parts for power plant turbine control system maintenance and retrofit projects.
