GE DS200UPLAG1

Detailed Technical Parameters

GE DS200UPLAG1 provides 16 digital input channels (24V DC nominal, with 1ms hardware debounce and timestamping capability), 16 digital output channels (solid-state relays rated at 0.5A continuous per channel with 60V DC maximum switching voltage and integrated thermal overload protection), and 8 analog input channels (16-bit resolution, configurable for 0-10V, 4-20mA, or ±10V with ±0.08% accuracy). The board’s distinguishing feature is its power system monitoring capability: 6 dedicated AC voltage input channels (0-600V AC, isolated, with 0.2% accuracy) and 6 dedicated AC current input channels (0-5A or 0-1A, isolated, with 0.2% accuracy), supporting both PT (potential transformer) and CT (current transformer) inputs. The board incorporates 4 dedicated frequency measurement channels for grid synchronization, measuring 45-65Hz with 0.001Hz resolution. Onboard processing handles synchronization logic, under/over frequency protection (81), voltage protection (27/59), and load sharing calculations. Communication occurs through a proprietary backplane interface at 8MB/s with 10ms cycle time. GE DS200UPLAG1 draws approximately 22W from the backplane rails and features conformal coating with vibration tolerance rated at 5G.

Advantages & Features

GE DS200UPLAG1 offers several distinctive advantages that differentiate it from standard I/O boards and from third-party synchronizers. The integration of power monitoring, synchronization, and protection functions directly into the Mark V chassis eliminates separate synchronizer panels, reducing cabinet footprint and simplifying system architecture. The dedicated AC inputs with isolated CT/PT connections provide accurate generator monitoring for precise control. The onboard frequency measurement with 0.001Hz resolution enables precise grid synchronization. Full integration with Mark V generator control algorithms ensures seamless coordination between turbine governor and grid requirements.

Application Cases & Application Fields

GE DS200UPLAG1 is deployed in power generation facilities requiring precise generator synchronization and grid monitoring. In a 500MW combined-cycle plant, the board provides accurate voltage and frequency measurement for grid synchronization. In an island mode application, it enables load sharing between multiple generators. The board is also used in industrial cogeneration facilities for grid interconnection and compliance monitoring.

Competitor Comparison

Versus standard GE DS200UCIBG3AAB, GE DS200UPLAG1 adds dedicated AC power monitoring and synchronization capabilities. Versus third-party synchronizer panels, the UPLA integrates seamlessly with Mark V control logic and eliminates separate hardware, but with potentially lower channel count than commercial power monitors.

Selection Suggestions

Choose GE DS200UPLAG1 for Mark V installations requiring generator synchronization, grid interconnection, or power system monitoring. Verify PT/CT ratings match field installation. Maintain spares considering 14-18 week lead times.

Critical Precautions

Never ground AC signal shields at the GE DS200UPLAG1 connector—ensure proper PT/CT grounding. Install external protection for CT circuits to prevent open-circuit conditions. Verify PT/CT ratios in application software. Perform software isolation before hot-swapping. Calibrate power channels annually. Store spares at 15-35°C and rotate every 4 years. Over 40% of field issues trace to improper CT/PT connections—verify wiring before commissioning.
