Working Principle:
The DX1043 samples all 4 input channels every 0.2 seconds. A 16-bit ADC converts analog signals to digital values. The microprocessor processes the data, applies linearization (for TC/RTD), and stores it in flash memory. The LCD displays real-time trends, bar graphs, and numerical values. Alarm logic continuously compares input values against user-set limits. When a limit is violated, the corresponding relay closes. Data is transmitted via Modbus RTU or Ethernet to SCADA/DCS systems.

Advantages & Highlights:

• Replaces mechanical chart recorders with zero consumable cost
• Universal input reduces spare parts inventory
• Event recording with 10 ms resolution captures fast transient events
• Compact panel-mount design fits existing chart recorder cutouts
• Ethernet connectivity enables remote monitoring and data retrieval

Applicable Industries:

• Chemical and petrochemical plants
• Oil refineries
• Power generation and distribution
• Water treatment facilities
• Pulp and paper mills
• Steel and metal processing

Installation Requirements:

• Install in a control room or panel with ambient temperature 0–55°C
• Leave 25 mm clearance on top and sides for heat dissipation
• Use twisted-pair shielded cable for TC inputs; 3-wire connection for RTD
• Ground the chassis to the plant earth ground
• Configure the input type for each channel in the setup menu before connecting signals

Usage Precautions:

• Do not exceed the maximum input voltage of 30 V DC on current input terminals
• Do not apply voltage to the recorder when the terminal cover is removed
• Perform a zero-point check after initial installation
• Back up recorded data at least once per month
• Do not use organic solvents to clean the front panel (use mild detergent and water only)
