Model Code Breakdown:

• DX106: DX1000 series, 6-channel recorder
• 2-2: Specific configuration code (indicates input type and output options)

Structural Features:

• DIN rail mounting (35 mm rail) or panel mounting
• Front panel with color LCD and membrane keypad
• Removable terminal block for easy wiring
• SD card slot for data backup and firmware update

Working Principle:
Analog input signals are converted by a 24-bit A/D converter with high-speed sampling. The microprocessor processes the data, applies linearization (for TC/RTD), scaling, and engineering unit conversion. Data is stored in non-volatile flash memory and displayed as real-time trends, bar graphs, and numerical values. Alarm functions compare each channel against user-defined setpoints with hysteresis.

Advantages & Highlights:

• Replaces paper chart recorders — zero consumable cost (no paper, ink, or pens)
• 6.5-inch color display provides clear, simultaneous multi-channel trend viewing
• 10 million data point memory enables long-term data logging without data loss
• Ethernet connectivity enables remote monitoring and data retrieval via PC/SCADA
• Built-in math functions: totalization, averaging, rate of change, deviation

Applicable Industries:

• Manufacturing process monitoring (injection molding, extrusion, heat treatment)
• HVAC system monitoring and energy management
• Water and wastewater treatment plants
• Food and beverage production lines
• Pharmaceutical batch recording (21 CFR Part 11 capable with optional software)

Installation Requirements:

• Mount on DIN rail or panel in a location with good visibility and access for wiring
• Keep away from strong electromagnetic interference sources (transformers, VFDs)
• Use shielded cables for TC and RTD inputs
• Connect ground terminal to plant earth ground

Usage Precautions:

• Do not connect voltage inputs exceeding the rated range (maximum 100 V DC for voltage inputs)
• For TC inputs, use the correct thermocouple type — mismatched type will cause large measurement errors
• Backup data to SD card periodically to prevent data loss in case of memory failure
• Do not open the enclosure in explosive atmospheres — use an explosion-proof barrier if required
