Yokogawa UD1045B0KC-2XN
Working Principle: The UD1045B0KC-2XN acquires analog and digital input signals from field instruments, converts them via high-speed A/D converters (16-bit resolution), and displays/records the data on a color TFT LCD screen. Data is stored in internal flash memory (up to 8 GB) and can be exported via USB, Ethernet, or RS-232C. The recorder supports real-time trend display, bar graph, numerical display, and alarm monitoring.

Material Composition:
- Front Bezel: Flame-retardant Polycarbonate (Smoke Gray)
- Housing: Aluminum Die-Cast with Powder Coat Finish
- Display Cover: Scratch-resistant Polycarbonate with anti-glare coating
- Terminal Block: Screw-type, 1.5 mm² to 2.5 mm² wire size
- Internal PCB: FR-4 Glass Epoxy, conformal coated
Structural Features:
- Panel-mount design (96 × 96 mm cutout)
- 8.4-inch wide color display — supports multi-window layout (trend + bar graph + numerical simultaneously)
- USB port on front panel — direct data export to flash drive
- Ethernet port — remote access via web browser
- Alarm annunciation LED on front panel
- Internal clock with battery backup — maintains time stamp during power loss
Applicable Industries:
- Oil & Gas (Upstream, Midstream, Downstream)
- Chemical & Petrochemical
- Power Generation (Thermal, Nuclear, Hydro, Renewable)
- Water & Wastewater
- Pharmaceutical
- Food & Beverage
- Steel & Metals
- Pulp & Paper
Advantages & Highlights:
- 45-channel capacity — consolidates multiple recorder functions into one unit
- 8.4-inch color display — superior visibility vs. monochrome recorders
- 8 GB internal memory — eliminates need for external storage in most applications
- Ethernet + USB + RS-232C — flexible data export and remote monitoring
- Multi-window display — trend, bar graph, and numeric values simultaneously
- HART input support — can accept HART field devices directly
- Event recording — captures sequence-of-events for troubleshooting
Installation Requirements:
- Cut 96 × 96 mm panel opening for flush mounting
- Use shielded twisted-pair cable for analog inputs (TC/RTD)
- Connect Ethernet cable (CAT5e or higher) for remote access
- Verify power supply voltage matches nameplate rating (100–240 V AC)
- Ground the recorder chassis to plant earth ground
- Configure channel assignments and alarm setpoints via front panel or PC software (UTAdvanced Logger) before commissioning
Usage Precautions:
- Do not exceed 45 input channels — each channel consumes scan cycle time
- Backup data regularly via USB or Ethernet — internal memory is not infinite
- Do not expose to direct sunlight — display degradation may occur above +50°C
- Clean front panel with soft dry cloth — do not use solvents on display
- Update firmware periodically via Yokogawa UTAdvanced Logger software
- Use surge protector on power line to protect against voltage spikes
