Products Description
GE DS200TBQCG1A Analog Input Termination Board
GE DS200TBQCG1A is an analog input termination board for GE Mark V Speedtronic gas and steam turbine control system. It receives 4-20mA analog signals from field transmitters and sensors, converting and forwarding these measurement signals to the main turbine controller for closed-loop regulation.
This board is equipped with terminal blocks, configurable jumpers and multi-pin ribbon connectors for signal scaling and wiring setup. It collects critical process parameters including pressure, temperature and flow for turbine monitoring. It is an obsolete legacy PCB, widely used as spare parts for existing power plant Mark V turbine control cabinets.
