GE DS200UPLAG1ADC

Detailed Technical Parameters

GE DS200UPLAG1ADC 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 ±0.05% accuracy across the full -30°C to +65°C operating range—the highest accuracy among all UPLA G1 variants). The board’s distinguishing feature is its power system monitoring capability: 6 dedicated AC voltage input channels (0-600V AC, isolated, with 0.10% accuracy) and 6 dedicated AC current input channels (0-5A or 0-1A, isolated, with 0.10% accuracy), supporting both PT and CT inputs with precision reference components and enhanced filtering for superior measurement stability. 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, with the “ADC” configuration including refined measurement algorithms for maximum accuracy. Communication occurs through a proprietary backplane interface at 8MB/s with 10ms cycle time. GE DS200UPLAG1ADC draws approximately 23W from the +5V DC and ±15V DC backplane rails and features conformal coating with vibration tolerance rated at 6G (10-500Hz) and shock resistance at 30G. All field connections terminate through three 50-pin D-sub connectors with gold-plated contacts and integral strain-relief brackets.

Advantages & Features

GE DS200UPLAG1ADC offers the highest accuracy among UPLA G1 variants, making it the premier choice for precision power measurement applications. The ±0.05% analog accuracy and 0.10% power measurement accuracy enable precise generator control, accurate performance monitoring, and reliable emissions compliance calculations. The precision reference components and enhanced filtering provide superior measurement stability over temperature and time. 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 “ADC” configuration represents the culmination of precision engineering across the UPLA G1 product line.

Application Cases & Application Fields

GE DS200UPLAG1ADC is deployed in facilities requiring maximum power measurement accuracy, including precision generator control, performance optimization, and emissions monitoring applications. In a 600MW combined-cycle plant, the ±0.05% accuracy enabled precise fuel-to-power optimization, improving heat rate by 0.3% and reducing annual fuel costs by $300,000.

Competitor Comparison

Versus GE DS200UPLAG1ADA (±0.06% analog, 0.12% power), the “ADC” provides superior accuracy. Versus third-party precision power monitors, the UPLA integrates seamlessly with Mark V control logic.

Selection Suggestions

Choose GE DS200UPLAG1ADC for applications requiring maximum power measurement accuracy. Specify the “ADC” suffix for precision measurement applications. Maintain spares considering 18-22 week lead times.

Critical Precautions

Never ground AC signal shields at the GE DS200UPLAG1ADC connector—ensure proper PT/CT grounding. Install CT shorting blocks. Calibrate power channels annually using certified reference instruments with accuracy at least four times better than the board specification. Over 40% of field issues trace to improper CT/PT connections.
