GE DS200IMCPG1C I/O Microprocessor Board

The GE DS200IMCPG1C is an I/O microprocessor control board designed for the GE Mark V Speedtronic turbine control system. It independently processes input and output channel data and communicates with the main controller through the rack backplane bus.

This board manages local I/O data collection, signal filtering and data packaging, and supports continuous hardware self‑diagnosis. It is widely stocked as replacement spare parts for power plant turbine control cabinet maintenance, outdated board renewal and system transformation projects.
