Products Description
GE DS200TBQBG1A Digital I/O Termination Board
GE DS200TBQBG1A is a digital I/O termination board for GE Mark V Speedtronic gas and steam turbine control system. It serves as the wiring termination interface for field digital signals, connecting field switches and relay signals to the main turbine controller backplane.
This board is equipped with dual large terminal blocks, multiple jumpers and multi-pin connectors for signal routing and wiring configuration. It handles discrete binary signals for turbine interlock, trip and auxiliary equipment status monitoring. It is an obsolete legacy hardware used for spare parts replacement of old power plant turbine control cabinets.
