The Pro-face 5.7-inch touchscreen (PNP model) AST3401-T1-D24 is a compact and robust human-machine interface (HMI) designed for industrial automation environments. It features a controller DIO (PNP type) with 6 NPN inputs and 2 NPN outputs, utilizing a 12-pin connector. This unit is classified as a DC24/C (control) grade model, ensuring reliable performance in control-oriented applications.

The display is a 5.7-inch STN pseudo-color LCD with a resolution of 320×240 pixels (QVGA), capable of rendering up to 4096 colors. Brightness is managed by a cold cathode lamp, and backlight replacement requires return to service. The touch panel is resistive (analog), providing accurate and durable touch response suitable for gloved or industrial use.

Data transfer is conveniently supported via USB memory, allowing operators to easily update screen data in response to production line changes directly on the factory floor. This capability significantly reduces downtime and enhances operational flexibility.

The device is equipped with five major efficiency-boosting functions. The GP-Pro EX software enables the creation of clear, high-quality screens with minimal effort. Its intuitive drag-and-drop and point-and-click interface simplifies the design process, even for beginners. Advanced features such as 3D components, image fonts, and powerful functions further streamline screen development.

Error visualization is made possible by connecting the controller directly to the GP and using sample components to display critical error messages, improving troubleshooting and response times.

Remote operation and monitoring are supported, allowing users to access and control GP screens from an office or remote location without additional programming. This facilitates real-time management and more efficient remote maintenance.

Upgrade compatibility is a key feature, as the GP/ST series supports screen data from all GP series models, including the legacy GP10 series. The product family maintains panel cutout compatibility, making replacement straightforward and cost-effective.

PC-based simulation allows users to test all GP functions—including screen operation, D scripts, and logic scripts—without transferring data to the actual device. This accelerates development and validation.

Video-based operation and maintenance instructions help reduce training and support costs, enabling any operator to quickly understand procedures. Additionally, the GP allows PLC programming without opening the control cabinet, thanks to its data pass-through function, which simplifies debugging and data adjustment during production line changes.

Monthly and daily report backups are easily performed using USB memory or CF cards, improving reporting efficiency. The CSV data conversion function enables PLC settings to be modified directly from the GP.

A rich library of sample screens and 3D components is available, significantly reducing programming time and helping users create visually appealing and intuitive interfaces. Overall, the Pro-face AST3401-T1-D24 offers a versatile, user-friendly, and efficient solution for modern industrial automation needs.
