Pro-face GP-4301TM

The Pro-face GP-4301TM (Model Number: PFXGM4301TAD) is a unique, high-performance 5.7-inch HMI from the GP4000 Series.¹

The “M” in the model suffix stands for “Modular,” which is the most significant feature of this unit. Unlike traditional HMIs that require a large rectangular cutout, this model mounts through a standard 22 mm circular hole (the same size used for industrial push-buttons), making it incredibly easy to install or retrofit.

1. Display and Visuals

• Screen Size: 5.7-inch.²

   

• Display Type: TFT Color LCD.³

   

• Resolution: ⁴$320 \times 240$ pixels (QVGA).⁵

   

• Colors: 65,536 colors.⁶

   

• Backlight: White LED with 16 levels of brightness control via software.⁷

   

2. The Modular (22 mm) Design⁸

The unit consists of two separate parts:

1. Display Module: The screen that sits on the front of the panel.

2. Rear Module: The “brain” containing the CPU and ports that snaps onto the back.

• Installation Advantage: You only need to drill a 22 mm hole.⁹ This eliminates the need for jigsaw cutting and allows for mounting on thick panels or even on a swing arm where space is tight.

   

3. Connectivity and Ports

Despite its small mounting footprint, it is fully featured:

• Ethernet: 1x RJ45 port (10/100 Base-T) for PLC communication and remote monitoring.¹⁰

   

• Serial (COM 1): RJ-45 type connector supporting RS-232C / RS-485. (Note: Requires a specific adapter cable to convert to 9-pin D-Sub).

• USB (Type A): For connecting USB sticks (data logging/recipes) or peripherals like barcode scanners.

• USB (Mini-B): Dedicated port for PC programming.

4. Technical Specifications

5. Key Features

• Pro-face Remote HMI: Supports remote viewing and operation from a tablet or smartphone.¹¹

   

• Wide Driver Support: Can communicate with a massive range of PLCs (Schneider, Rockwell, Siemens, Mitsubishi, etc.).

• Pass-Through Function: Allows you to program the connected PLC through the HMI using a PC.

• Battery-less: Uses non-volatile memory for data backup, meaning you don’t have to worry about replacing a lithium battery for memory retention.

Replacement/Maintenance Tip:

If you are replacing an older GP3000 series unit with this “TM” model, remember that you no longer need the large square hole. If the hole is already there, Pro-face sells an “Adapter Plate” to cover the old large cutout while using the 22 mm mounting nut of the GP-4301TM.

Would you like me to find the “RJ45 to 9-pin D-Sub” serial pinout for this model, or do you need the “Panel Cutout” template for the 22 mm mounting?
