Product Description:
The GE DS200NATOG3ACB is a specialized Voltage Feedback Scaling Board designed for GE’s Speedtronic Mark V Turbine Control System—a triple-redundant microprocessor-based platform for gas/steam turbine management, known for features like combined-cycle STAG plant compatibility, full turbine-generator monitoring, and digital valve control. A revised variant of the original DS200NATOG3 board, its core role is to manage and scale voltage feedback from an SCR bridge: it attenuates high AC/DC voltages from the SCR bridge to levels safe for the Mark V control system, ensuring accurate feedback measurement.
It integrates closely with other Mark V components: it collaborates
with a gate distribution/status board and connects to the VME
backplane. Hardware-wise, it features five series-connected
precision resistor strings configurable via 3 input stab connectors
and 2 wire jumpers to handle 5 voltage levels. Outputs from the
resistor strings feed into a 20-pin ribbon header, with each output
protected by a metal oxide varistor to clamp excess voltage.
Key Features:
Targeted SCR Voltage Attenuation: Dedicated to scaling high AC/DC voltages from SCR bridges to control-system-safe levels, ensuring precise feedback measurement—critical for stable SCR operation and turbine control.
Configurable Voltage Handling: Five precision resistor strings adjustable via stab
connectors/jumpers to support 5 voltage levels, adapting to diverse
SCR bridge setups.
Integrated System Collaboration: Works with the gate distribution/status board and VME backplane,
embedding seamlessly into the Mark V’s turbine control
architecture.
Output Protection & Efficiency: 20-pin ribbon header (JV) centralizes outputs, with MOVs on each
output to clamp excess voltage; burden resistor placement on the
gate board streamlines the NATO board’s focus on attenuation.
Maintenance-Friendly Design: 6 test points enable easy diagnostic measurements; edge markings
and corner drill holes simplify alignment/mounting; clear component
labeling aids troubleshooting.
