Pro-face FP3900-T41-U / PFXFP3900TA Operating Panel

The Pro-face FP3900-T41-U (order code PFXFP3900TA) is a 10.4-inch graphic operating panel from the GP3000 series. It combines a high-resolution TFT LCD with an analog resistive touchscreen, providing a robust HMI solution for industrial control, machine monitoring, and data acquisition.

Display Characteristics

Active area: 211.2 mm x 158.4 mm. Resolution: 640 x 480 pixels (VGA). Colors: 65,536 colors (65k) without blinking, 16,384 colors with blinking. Backlight: CCFL rated 50,000 hours typical. Brightness: 350 cd/m². Contrast ratio: 500:1. Viewing angles: ±70° horizontal, ±60° vertical.

Touch Panel and Input

Analog resistive type, single-touch, glove-friendly. Touch resolution: 1024 x 1024. Activation force: 0.98 N max. Surface hardness: 3H. The front panel includes 6 programmable function keys (F1-F6) and a numeric keypad overlay option. LED backlight for keys.

Communication and Interfaces

• RS-232C (9-pin D-sub) for PLC connection.

• RS-422/485 (terminal block) for multi-drop.

• Ethernet 10BASE-T/100BASE-TX (RJ45) for network integration and web server.

• USB 2.0 host (Type A) for mouse, keyboard, or printer.

• USB 2.0 device (Mini-B) for screen transfer.

• SD card slot (support up to 32 GB SDHC).

Supported Drivers

The FP3900-T41-U connects to over 300 PLC models via Pro-face's built-in drivers, including Siemens (S7 MPI/PPI/Ethernet), Mitsubishi, Rockwell (DF1/Ethernet), Omron (Host Link), and Modbus RTU/TCP. Also supports OPC UA client functionality (firmware upgrade required).

Software and Development

Use GP-Pro EX (version 4.0 or later) to create projects. Features include animation, alarms, data logging (CSV to SD), multi-language text, and recipe management. The panel can operate as a data gateway, forwarding PLC data to a SQL database via its Ethernet port. Runtime firmware upgrades via SD card.

Power and Environment

Supply voltage: 24 VDC (18 to 28 V). Power consumption: 28 W max. Inrush current: 20 A (at 24 V). Operating temperature: 0°C to 50°C (mounting orientation horizontal). Storage temperature: -20°C to 60°C. Humidity: 10% to 90% non-condensing. Protection: front panel IP65 (dust-tight and water jets), rear panel IP20.

Memory and Performance

Flash ROM: 32 MB (user project area). DRAM: 64 MB. SD card expansion for logging. Data retention via non-volatile memory (no battery required for clock, but optional CR2032 for extended clock backup). Boot time: 15 seconds typical. Screen change time: < 0.5 seconds.

Applications and Certification

Used in food processing, pharmaceutical, automotive assembly, and packaging machinery. CE marked, UL listed (UL 60947-1), cUL, KC, and CCC. RoHS compliant. The FP3900 series are also ATEX certified for Zone 2/22 when installed with appropriate enclosure.
