Working Principle:
The DX2048T acquires analog and digital signals from field sensors via its universal input modules. The A/D converter digitizes each input at a 0.2-second scan cycle. Processed data is displayed on the 7-inch touchscreen in real time. The recorder continuously writes data to internal flash memory and can be scheduled to archive to USB/CF cards. The 4–20 mA output channels replicate selected input values for transmission to external controllers or indicators. Alarm outputs activate when configured limits are exceeded.

Advantages & Highlights:

• 48 channels in a single compact 1/8 DIN instrument — high channel density
• Touchscreen interface simplifies configuration and operation
• 3-split display provides comprehensive process overview without scrolling
• Dual recording (internal + removable media) ensures data security
• OPC UA and Modbus TCP enable seamless integration with DCS and SCADA

Applicable Industries:

• Oil Refining and Petrochemical
• Power Plants (boiler, turbine, generator monitoring)
• Steel and Metal Processing
• HVAC and Building Automation
• Water Treatment Plants
• Food Processing

Installation Requirements:

• Cut panel opening to 96 × 96 mm with maximum depth clearance of 150 mm
• Mount in a location free from direct sunlight, excessive vibration, and corrosive atmosphere
• Use shielded twisted-pair cables for TC/RTD inputs; ground shields at one end only
• Provide dedicated 100–240 V AC power supply with ≤ 5% voltage fluctuation
• Ethernet cable: CAT5e or higher, maximum 100 m run

Usage Precautions:

• Do not exceed the maximum input voltage of 30 V DC or 250 V AC on any channel
• Ensure proper cold junction compensation for thermocouple inputs
• Back up data to removable media before performing firmware updates
• Clean the touchscreen with a soft, dry cloth — do not use solvents
• Replace the internal battery (for clock backup) every 2 years
