GE DS200QTBAG1A Terminal Board

The GE DS200QTBAG1A is a field terminal connection board designed for the GE Mark V turbine control system. It serves as a signal junction to route field wiring signals to the main control boards inside the rack and provides stable signal transmission channels.

This terminal board simplifies on‑site wiring layout and isolates external field circuits from internal control cards. It is widely stocked as replacement spare parts for power plant turbine cabinet maintenance, aged terminal board renewal and control system renovation projects.
