Key Features and Performance Benefits

4.3” to 15.6” LCD TFT display options allow flexible installation in compact control panels or large monitoring stations, helping manufacturers optimize operator interface visibility while saving cabinet space. 
480×272 to Full HD 1920×1080 resolution ensures clear data visualization and sharp graphics display, improving operator accuracy and reducing operational errors in complex production processes. 
250–400 cd/m² high brightness ensures stable screen readability in strong ambient lighting conditions, enabling reliable operation in factories, workshops, and outdoor cabinets. 

Industrial resistive touch panels provide reliable input performance when operators wear gloves, while capacitive multi-touch panels deliver smartphone-like smooth operation for advanced HMI interface control. 
Cortex-A7 / Cortex-A8 high-performance processors ensure fast data processing and smooth interface response, helping reduce system latency and improve real-time machine control efficiency. 

Up to 4GB storage capacity supports large project files, historical data logging, and advanced HMI applications without external storage dependency.
Low power consumption from <5W to <18W helps reduce system energy costs and heat generation, improving long-term system stability and panel lifespan. 
Wide DC 24V input voltage range supports unstable industrial power environments, improving device reliability and reducing downtime risks.
Lightning surge protection and <5ms power failure tolerance protect critical data and prevent sudden system shutdown failures. 
Front IP65 protection ensures resistance against dust, oil, and water splash, making the HMI suitable for harsh industrial production environments. 
Multi-protocol serial communication (RS232/RS485/RS422) enables seamless integration with PLCs, drives, sensors, and legacy industrial equipment. 
Optional WiFi and 4G IoT modules support remote monitoring, cloud data transmission, alarm notification, and remote PLC program updates, helping enterprises build smart factory infrastructure.
