The Pro-face 3.8-inch touchscreen model AGP3750-T1-AF-M is a standard-grade, DC24V-powered operator interface designed for industrial automation environments. It features a monochrome LCD display with amber/red coloration, offering a resolution of 320×240 pixels (QVGA) and 8-level grayscale rendering. The backlight uses amber/red LEDs that are factory-replaceable only, with 16-step brightness adjustment accessible via the touch panel. The resistive analog touch panel ensures reliable input even in harsh conditions.

This model is supported by Pro-face’s extensive library of pre-designed screens and 3D components, significantly reducing programming time and enabling intuitive, visually clear interface creation. Data transfer is conveniently handled via USB memory, allowing quick updates for production line changes. The device supports easy upgrades and incorporates robust security features, including password-based access control with customizable levels per operator or manager, requiring ID and password entry for operation.

A standout capability is the GP’s data pass-through function, which allows direct PLC program debugging and parameter adjustments from the GP without opening the control cabinet. Monthly and daily report backups are streamlined using USB memory or CF cards, and CSV data conversion enables PLC settings modifications directly on the GP. The GP/ST series maintains backward compatibility with all GP series models, including the first-generation GP10, and ensures panel cut-out size consistency for straightforward replacements.

Five core efficiency-enhancing functions are integrated: intuitive screen creation via GP-Pro EX software with drag-and-drop simplicity, 3D parts and image fonts for faster design, video-based operation and maintenance instructions to reduce training costs, PC simulation for offline testing of all GP functions including D scripts and logic scripts, and remote monitoring and control from office locations without additional programming. Error visualization is also supported by connecting controllers directly to the GP and using sample parts to display critical fault information, enabling real-time issue identification and more effective remote maintenance control.
