GE DS200DTBBG1A Digital Contact Input Terminal Board

The GE DS200DTBBG1A is a high‑density digital contact termination board built for the GE Mark V Speedtronic turbine control system. It serves as an interface between field contact devices and internal control cards to receive discrete switching status signals.

This terminal board is equipped with multiple terminal blocks and ribbon cable connectors for centralized wiring and signal distribution. It is widely stocked as a replacement spare for power plant turbine cabinet maintenance, aged terminal hardware renewal and control system retrofitting projects.
