GE DS200SVAAG1A Mark V AC Voltage Attenuator Board
The GE DS200SVAAG1A, also cataloged as the DS200SVAAG1A AC Voltage Attenuator Board, operates as a dedicated hardware component for high-voltage AC signal scaling and galvanic isolation within Speedtronic Mark V turbine control systems. The board conditions generator terminal and busbar voltage inputs down to low-level analog signals compatible with downstream DS200ADCI analog input cards.

Backplane Bus Communication Velocity Licences and Deterministic Execution
The DS200SVAAG1A conditions raw high-voltage AC inputs directly at the rack boundary using precision resistor networks and isolation amplifiers. By performing signal scaling and galvanic separation locally prior to analog-to-digital conversion, the board prevents high-voltage transients from penetrating the core processing architecture. This localized signal conditioning maintains predictable analog sampling integrity without imposing computational overhead or degrading backplane bus communication velocity across primary controller racks.
Frequently Asked Questions
Q: How does the DS200SVAAG1A handle power distribution from the Mark V chassis?
A: The module draws operational power directly from the Mark V backplane bus, utilizing +5 VDC for logic circuits and +/-15 VDC for onboard precision isolation amplifiers.
Q: What interface board receives the output signals processed by the DS200SVAAG1A?
A: The board conditions and scales raw high-voltage AC inputs into low-level AC voltage signals specifically calibrated for routing to the DS200ADCI analog input board.
Q: Are individual channel test points accessible for field diagnostic checks?
A: Yes, the board surface features dedicated diagnostic test points alongside the 8 field terminal connections (SC1-SC8) to permit direct voltage verification using standard multimeter probes.
Field Installation Guidelines
Align the DS200SVAAG1A board with the designated VME slot guides in the Mark V enclosure. Slide the unit firmly into place until the backplane connectors seat completely, then tighten the top and bottom retaining screws to ensure proper mechanical mounting and frame grounding.
Route high-voltage AC input lines from generator terminals or busbars to terminals SC1 through SC8 on the terminal block. Ensure signal wiring maintains proper clearance from low-voltage digital ribbon cables to avoid noise coupling. Verify that all field connections are fully de-energized prior to attaching conductors to prevent electrical shock or hardware damage.
