Wecon Technology LEV1430T Levi Human Machine Interface ** TESTED AND WORKING **

1. General Overview

• Brand: Wecon Technology
• Series: Levi Series (LEV / LEVI)
• Model: LEV1430T
• Type: Human Machine Interface (HMI)
• Power: 24V DC

This is a compact mid-range color HMI, mainly used in small industrial machines.

2. Display System (User Interface Layer)

• Screen size: 4.3 inch TFT LCD
• Resolution: 480 × 272 pixels
• Colors: 65,536 colors
• Brightness: ~300 cd/m²
• Backlight: LED (~50,000 hours)

Engineering Insight:

• Good for:
  • Basic graphical screens
  • Small dashboards
• Not suitable for:
  • Large SCADA-style visualization

3. Touch Panel

• Type: 4-wire resistive touch
• Surface hardness: ~4H
• Works with:
  • Gloves
  • Dust / oil

Ideal for industrial environments, not for smartphone-like smooth touch.

4. Internal Hardware ArchitectureCPU

• 32-bit RISC processor
• Speed: 300–400 MHz range

Memory

• Flash: 128 MB
• RAM: 64 MB DDR

Meaning:

• Supports:
  • Moderate project size
  • Multiple screens
• Limited for:
  • Heavy data logging
  • Complex UI

5. Communication InterfacesSerial Communication

• COM1: RS-232 / RS-422 / RS-485
• COM2: RS-232

Supports:

• Modbus RTU
• Mitsubishi, Siemens, Delta, Omron PLC

USB Ports

• USB Host (pendrive, data backup)
• USB Client (program download)

Ethernet

• Most LEV1430T variants: No Ethernet

Important limitation compared to modern HMIs.

6. Electrical Specifications

• Input voltage: 24V DC (12–28V range)
• Power consumption: < 5 W

Very low power → suitable for small control panels.

7. Environmental Specifications

• Operating temp: -10°C to 60°C
• Storage temp: -20°C to 70°C
• Humidity: 10–85% RH
• Protection: IP65 (front panel)

Works well in:

• Dusty factories
• Machine panels

8. Mechanical Details

• Dimensions: approx. 142 × 86 × 30 mm
• Mounting: Panel mount
• Weight: ~0.3 kg

Very compact → good for tight panels.

9. Software & ProgrammingSoftware:

• PIStudio (Wecon HMI software)

Features:

• Alarm display
• Data monitoring
• Macro scripting
• Recipe handling
• Multi-language support

Software is simple but not as advanced as:

• Siemens WinCC
• Weintek EBPro

10. Working PrinciplePLC ⇄ (RS232 / RS485) ⇄ HMI ⇄ OperatorOperation:

1. PLC sends data (registers/inputs)
2. HMI reads values
3. Displays:
   • Numbers
   • Status
   • Operator presses screen
   • HMI sends command back to PLC

11. Supported PLCs

Compatible with:

• Mitsubishi FX/Q series
• Siemens S7-200 / S7-300
• Delta PLC
• Omron CP series
• Allen-Bradley MicroLogix

12. Applications

Used in:

• Packaging machines
• Small OEM machines
• Textile machines
• Water systems
• Basic automation are typically processed within 7-10 business days. Large orders or special equipment may take up to 10 business days.
• Buyer pays for return cost if purchase wrong item, does not like item. (No error from Seller Side).
