Structural Characteristics:

• Form Factor: Panel-mount (1/4 DIN cutout: 138 mm × 138 mm)
• Dimensions: 144 mm (W) × 144 mm (H) × 120 mm (D) (approximate, excluding protrusions)
• Weight: Approximately 1.8 kg
• Cutout Size: 138 mm × 138 mm (panel mounting)

Operating Principle:
The DY150 samples each input channel at a configurable rate (100 ms to 60 s), converts the analog or digital signal to engineering units using the configured input type and range, and stores the data with a timestamp in the internal flash memory. The data is simultaneously displayed on the TFT LCD in real-time trend, bar, or numeric format. When an alarm condition is detected, the corresponding relay output energizes, and an alarm event is logged with timestamp. Data can be exported via USB or transmitted over Ethernet/RS-485 to a SCADA or historian system using Modbus TCP/RTU protocol.

Advantages & Highlights:

• Zero Paper Consumption: Eliminates chart paper, ink, and pen replacement — reduces operating cost by > 80% vs. chart recorders
• High-Resolution Display: 640 × 480 color TFT provides clear, detailed trend visualization
• Universal Input: Accepts all major sensor types on a single unit — no need for dedicated modules
• Robust Front Panel: IP65 / NEMA 4 rating allows installation in harsh, wet, or dusty environments

Applicable Industries:

• Chemical & Petrochemical Plants
• Power Generation (Thermal/Nuclear)
• Pharmaceutical & Biotech
• Food & Beverage Processing
• Water & Wastewater Treatment
• HVAC & Building Automation

Installation Requirements:

• Cut a 138 mm × 138 mm panel opening; verify gasket seal before mounting
• Connect inputs using shielded cable; ground shields at the recorder end only
• Provide 100–240 V AC, 50/60 Hz power with ≤ 10% voltage fluctuation
• For Ethernet communication, use Cat 5e or higher shielded cable (max 100 m)
• Maintain ambient temperature 0 to 50 °C; avoid direct sunlight on the display

Usage Precautions:

• Do not exceed the maximum input voltage/current for any channel — refer to the input specification table in the manual
• Perform a factory reset only after backing up all recorded data to USB
• Do not open the front bezel in environments with dust or corrosive gases — the IP65 seal will be compromised
• Replace the internal backup battery (CR2032) every 2 years to prevent data loss on power failure
• Do not use USB flash drives exceeding 32 GB — the recorder may not recognize them
