Product Description
GE DS200XDSAG1A is a digital signal output relay board in the DS200 hardware family for the Speedtronic Mark V turbine control system. It plugs directly into the Mark V rack backplane, converting internal controller logic signals into galvanically isolated relay contact outputs to drive field solenoid valves, auxiliary relays, status indicators and alarm circuits. It supports channel-level self-diagnosis to report open-circuit and hardware faults in real time. With galvanic isolation to suppress electrical transients from inductive loads, it acts as a critical I/O spare for protection and sequence logic execution of gas and steam turbines.
