Yokogawa DX2010T-3-4-2
Product Overview:
The DX2010T-3-4-2 is the touchscreen variant of the DX2010-3-4-2 paperless recorder. It features a 3.5-inch color TFT touchscreen instead of a monochrome LCD, providing intuitive operator interaction, trend visualization, and bar graph display. All functional specifications match the DX2010-3-4-2 with the addition of a color touchscreen interface.

Functional Features:
- Color touchscreen interface: Touch-based navigation, trend display, and bar graph
- 3 universal inputs accept any standard process signal
- 4 isolated 4-20 mA outputs for direct valve control
- 2 alarm relay outputs with configurable setpoints
- Math functions: Addition, subtraction, multiplication, division, square root, moving average
- Linearizer: Up to 30-segment piecewise linearization
- Totalizer: Flow totalization with reset
- HART communication: Configure and calibrate HART smart transmitters via touchscreen
- Color trend display: Real-time color-coded trend graphs on the 3.5-inch screen
- Multi-language support: English, Japanese, Chinese, and other languages
Working Principle:
Identical to the DX2010-3-4-2. The 3.5-inch color TFT touchscreen is driven by a dedicated graphics controller that renders trend graphs, bar graphs, and menu screens in color. The resistive touchscreen uses a 2-layer membrane with analog voltage detection for touch position. The processor executes the same recording, control, and communication functions as the DX2010-3-4-2, with the added capability of displaying color-coded trends and bar graphs on the larger, higher-resolution screen.
Advantages and Highlights:
- Color touchscreen provides superior usability compared to button-only operation
- Intuitive trend visualization — operators can see process behavior at a glance
- All DX2010-3-4-2 functions retained in a compact 96×96 mm form factor
- Dual power supply (AC/DC) for installation flexibility
- 4 isolated analog outputs eliminate need for external I/P converters
- HART touchscreen configuration — no need for a separate HART communicator
Applicable Industries:
- Oil and Gas
- Chemical and Petrochemical
- Power Generation
- Water and Wastewater
- HVAC and Building Automation
- Food Processing
Installation Requirements:
- Cut panel opening to 92 mm × 92 mm for flush mounting
- Secure with 4 × M4 mounting screws
- Connect power: 100-240 V AC or 24 V DC with proper grounding
- Use shielded twisted-pair cable for all analog input connections
- Install 120Ω termination resistor at the end of RS-485 bus
- Ensure minimum 50mm clearance above and below the unit for ventilation
Usage Precautions:
- Calibrate the touchscreen if touch response becomes inaccurate (perform via front panel menu)
- Do not apply input signals exceeding the maximum rated value for the selected input type
- Use a soft cloth or stylus for touchscreen operation — do not use sharp objects
- Perform initial calibration after installation using a precision signal source
- Do not expose the touchscreen to direct sunlight or temperatures above +50°C
- Back up recorded data via RS-232C or USB adapter before memory fills
