Description
DS200UPLAG1BDA Product Overview
The DS200UPLAG1BDA is a dual-function board used inside GE Mark V and UC2000 Speedtronic control cubicles. It combines low-voltage power-supply regulation with LAN/communication interface routing, eliminating the need for separate PSU and comms cards in medium-voltage drive or excitation systems.
The DS200UPLAG1BDA is a dual-function board used inside GE Mark V and UC2000 Speedtronic control cubicles. It combines low-voltage power-supply regulation with LAN/communication interface routing, eliminating the need for separate PSU and comms cards in medium-voltage drive or excitation systems.
In the control hierarchy the card sits at the “power & comms distribution” layer:
-
It accepts 85–264 VAC universal mains and generates +5 V, +12 V, and +24 V rails required by the CPU, memory, and I/O modules.
-
It also routes LAN signals (typically 10 Mb Ethernet or proprietary serial) between the processor and external HMI/SCADA devices through ribbon-cable headers.
All connections are made through front-panel keyed headers (26-pin, 8-pin, and 2-pin), keeping 115/230 VAC mains away from the low-voltage backplane. 17 jumpers and 16 DIP switches allow site-specific configuration (baud rate, power-sequence timing, LAN enable) without software downloads.
Because the board is conformal-coated and rated -40 … +85 °C, it survives the heat, humidity, and vibration common in turbine compartments without additional HVAC.

Core Features & Customer Value
Universal 85–264 VAC input – Accepts worldwide mains without tap changes, simplifying spares and site engineering
Universal 85–264 VAC input – Accepts worldwide mains without tap changes, simplifying spares and site engineering
.
Dual-function design – Combines PSU and LAN interface in one card, freeing Mark V slots and reducing spare-part count.
Ribbon-cable LAN routing – Routes 10 Mb Ethernet or proprietary serial through keyed 26-pin headers, eliminating external comms cards and their associated wiring errors
.
17 jumpers + 16 switches – On-board hardware allows baud-rate, power-sequence, and LAN-enable changes without software tools, keeping commissioning time low
.
Zone-2 / marine certified – Conformal-coated PCB is certified for Class I Div. 2 and offshore environments, allowing direct installation in hazardous-location turbine skids without additional purge systems
.
Typical Applications
In combined-cycle power plants the DS200UPLAG1BDA is installed in Mark V excitation cubicles that supply the generator field. It powers the processor and routes LAN data to the remote HMI, while the 24 V rail energises contactor coils and indicator lamps

.
In pipeline compressor stations the same card is used in UC2000 drive racks that control centrifugal compressors; the universal mains input rides through plant battery float-voltage swings without nuisance shutdowns
.
Because the board is certified for marine environments, it is also used on off-shore platforms for engine-driven generators where a fan-less, Zone-2, universal-mains power/interface card is mandatory
