Working Principle:
The UD1000 acquires up to 1,000 data points from a combination of analog inputs, digital inputs, and communication-based inputs (Modbus, HART). The high-speed A/D converter and digital input circuits feed data to the microprocessor, which processes, displays, and stores data at the configured intervals. The 8.4-inch TFT provides a comprehensive multi-window view. Data is archived to 10 million-point internal memory and dual USB ports. Ethernet and RS-485 interfaces enable SCADA/DCS integration.
Advantages & Highlights:
- 1,000 point capacity — suitable for plant-wide data acquisition in a single unit
- 8.4-inch color TFT with multi-window display provides unmatched visibility
- Dual USB ports enable simultaneous backup and data transfer
- China version (/CN) with GB compliance, Chinese language, and local support
- Communication input support (Modbus, HART) reduces need for additional signal conditioners
Applicable Industries:
- Large-scale chemical plants
- Power generation stations
- Oil refineries
- Water treatment facilities
- Pharmaceutical batch processes
- Steel mills
Installation Requirements:
- Panel cutout: 92 × 188 mm (H × W)
- Power: 100–240 V AC, stable supply with ≤ 5% fluctuation
- Ethernet: CAT5e or higher, maximum 100 m
- RS-485: Shielded twisted pair, maximum 1,200 m
- Minimum 50 mm clearance above and below for ventilation
- Ground the chassis to plant earth (≤ 4 Ω)
Usage Precautions:
- Do not exceed 1,000 total configured points — this will cause data loss
- Configure input types correctly before connecting field signals
- Perform firmware updates only using Yokogawa-approved files
- Back up data to both USB ports before any major configuration change
- Clean the touchscreen with a soft, lint-free cloth; do not use alcohol-based cleaners
