GE DS200TCEAG1B Analog I/O Board

The GE DS200TCEAG1B is a plug‑in analog input and output board for GE Mark V Speedtronic turbine control systems. It acquires analog measurement signals and outputs control signals for turbine regulation.

This board communicates with the main controller via the rack backplane and integrates onboard diagnostic LEDs for fault indication. It is widely used as replacement spare parts for power plant turbine cabinet maintenance and system upgrading projects.
