GE DS200DTBDG1A Digital Input Terminal Board

The GE DS200DTBDG1A is a digital input termination board for GE Mark V Speedtronic turbine control systems. It acts as an interface between field contact devices and rack control cards to collect discrete digital status signals.

This board integrates multiple screw terminals and ribbon‑cable connectors for centralized wiring and signal distribution. It is widely stocked as replacement spare parts for power plant turbine cabinet maintenance, aged terminal board renewal and control system renovation projects.
