Technical Specifications
Display: 8.4-inch TFT color. Resolution: VGA 640×480. Display colors: 256. Power supply: 24V DC. Communication interfaces: Ethernet, RS-232/485. Operating temperature range: 0°C to +50°C. Front panel protection: NEMA 4X / IP65.
Functional Features
It provides high-definition color display with resistive touch screen operation. It supports multi-protocol communication, rich graphic controls and recipe management, alarm recording and data trend functions. The front panel is waterproof and dustproof.
Application Scenarios
It applies to machine tool operation interfaces, packaging production line monitoring, food and beverage production equipment, water treatment system monitoring, HVAC control systems, and small-scale production line human-machine interaction.
Performance Parameters
Display brightness: 250cd/m². Contrast ratio: 300:1. Response time: 20ms. Operating temperature range: 0°C to +50°C. Storage temperature range: -20°C to +60°C. Mean time between failures: 40,000 hours.
Structural Characteristics
It features rugged industrial plastic housing, sealed front panel design, panel mount structure, waterproof and dustproof front surface, and industrial-grade motherboard and storage.
Working Principle
As the core of human-machine interaction, it receives operation instructions from the touch screen, exchanges data with lower-level PLCs or controllers through communication interfaces, and displays equipment operation status, parameters and alarms graphically to operators.
Installation Requirements
Adopt panel mount installation with cutout size conforming to the installation manual. Ensure stable 24V DC power supply. Ground communication cable shields. Avoid installation in direct sunlight and high temperature positions.
Usage Notes
Clean the screen with a soft cloth and special detergent. Do not scratch the screen with sharp objects. Regularly check sealing performance. Perform wiring maintenance after power off. Do not disassemble internal circuits without authorization.
