Working Principle

1. 24 V DC external power supply input converts stable low-voltage DC power via internal power module for CPU, display, communication circuits and touch sensor;
2. ARM main processor runs HMI runtime operating system, loads user-configured project screen files stored in flash memory;
3. LVDS bus transmits graphical data to E30004380 display core to output real-time equipment running data, trend curves and alarm information;
4. Resistive touch panel collects operator touch coordinate signals and transmits to main CPU to execute screen switching, parameter modification and manual control commands;
5. Serial/Ethernet communication ports establish bidirectional data exchange with lower-layer PLC, frequency inverters and sensors, upload field real-time data and download control setpoints;
6. Internal flash memory automatically records equipment fault logs, production batch data, accessible and exported via front USB storage device.

Function Features

• Real-time process data visualization: numerical display, bar graphs, trend curve charts, alarm message pop-up windows
• Multi-level user authority password management to restrict parameter modification operation permissions
• Built-in alarm logging system with timestamp storage of all equipment fault and warning events
• Offline/online project program upload/download via USB flash disk or Ethernet network
• Multi-protocol industrial communication compatibility for cross-brand automation equipment networking
• Built-in real-time clock (RTC) module for accurate timestamp of all data records and alarms
• Scheduled data logging function, automatic cyclic storage of production parameter data

Performance Advantages

1. Complete integrated machine delivered with pre-factory aging test, plug-and-play after cabinet installation without additional assembly work;
2. Multi-brand PLC/drive protocol compatibility eliminates communication adapter hardware cost for mixed-brand automation production lines;
3. IP65 front panel withstands workshop water splashing, cutting fluid mist and dust accumulation without screen failure;
4. Front USB design realizes on-site data export without cabinet disassembly, improves maintenance efficiency;
5. Large-capacity flash memory supports long-term automatic production data storage without external auxiliary storage equipment;
6. Integrated clamping mounting structure simplifies cabinet installation, reduces installation time by 60% compared to screw-fixed HMIs.

Applicable Industries

Automated packaging lines, food & beverage processing equipment, plastic molding machinery, metal stamping machine tools, municipal water treatment control stations, textile looms, lithium battery assembly equipment, logistics sorting automation systems.

Installation Requirements

1. Cabinet cutout edge smooth without burrs to avoid scratching front panel silicone sealing ring;
2. Four clamping brackets evenly tightened to balance front panel pressure, prevent local sealing ring extrusion deformation and water ingress;
3. Power wiring uses shielded 2-core twisted pair cable, single-end shielding grounding at control cabinet terminal block;
4. Ethernet/RS485 communication cables separated from high-power inverter power cables with minimum 15 cm spacing to avoid signal interference;
5. Rear enclosure IP20 side must be installed inside sealed electrical cabinet, cannot expose to open workshop environment;
6. Maintain minimum 30 mm rear wiring clearance for heat dissipation and cable routing space.

Usage Precautions

• Forbid direct high-pressure water flushing of front touch panel; high water pressure breaks silicone sealing ring and enters internal circuit;
• Do not apply voltage exceeding 28.8 V DC to power terminals; overvoltage burns internal power supply module irreversibly;
• Avoid installing unit within 1 meter of high-power frequency converters without signal shielding isolation; electromagnetic noise causes screen flicker and touch misoperation;
• Do not wipe front panel with strong acid/alkali chemical cleaners; corrosive liquid damages front plastic and anti-glare coating;
• RTC battery internal to unit has 5-year service life; replace battery regularly to avoid loss of timestamp function after power cut;
• Do not plug/unplug USB storage device during data logging writing process, sudden disconnection causes data file corruption.
