Pro-face’s technical FAQ identifies GP450-EG12 as the standard GP-450E model with an EL display, 640 × 400-dot resolution, and a 259 × 201 mm panel cutout. It also states that GP-PROII V3.20 or later is compatible with the GP-450E.

Replacement Options

Pro-face currently lists the following replacement paths:

  • PFXGP4501TAA — GP4000 Series; same panel cutout; TFT color LCD; monochrome display mode available.
  • PFXGP4501TMA — GP4000 Series; same panel cutout; TFT color LCD; monochrome mode available; supports 2-point touch.
  • PFXGP4501TADW — GP4000 Series; different panel cutout; TFT color LCD; requires DC power; does not support 2-point touch.

These are replacement options, not necessarily electrical or software drop-in equivalents. Pro-face explicitly distinguishes the panel-cutout and power-supply differences.

 

Product Introduction

The Pro-face GP450-EG12 is a legacy 10-inch programmable HMI from the GP70/50/30/10 Series. The GP450-EG12 uses an EL display with 640 × 400-dot resolution and was designed for industrial operator-interface applications. Its GP-450E platform includes a printer port and AUX port.

This is an obsolete HMI, not a current-production unit. Pro-face records its end of sales as July 31, 2000 and end of repair as December 28, 2005. For an existing machine, retaining a tested original spare can avoid an immediate panel redesign, but replacement planning should consider the GP4000 options published by Pro-face.

Installation & Configuration Guide

Stage 1: Pre-Installation Preparation — 5–10 Minutes

⚠️ Safety First: Place the machine in a safe state and disconnect the HMI from its power source before removing the unit or its wiring.

Tools Required

  • ESD wrist strap
  • Phillips screwdriver
  • Multimeter
  • Cable labels
  • Smartphone or camera
  • Appropriate panel tools

Before Removal

  1. Notify operations about the maintenance window.
  2. Place the machine in a safe operating state.
  3. Isolate power to the HMI.
  4. Verify the absence of hazardous voltage.
  5. Photograph the existing GP450-EG12 from the front and rear.
  6. Record the model and hardware markings.
  7. Photograph the communication and AUX/printer connections.
  8. Back up the existing HMI project if the original engineering environment is available.

⚠️ Do not rely on a modern HMI project file being directly compatible with the GP450-EG12. The official documentation identifies GP-PROII V3.20 or later as the compatible screen-creation software for the GP-450E.

Stage 2: Removing the Old — Approximately 10 Minutes

  1. Remove the rear access hardware as required.
  2. Label every cable before disconnecting it.
  3. Disconnect the PLC communication cable.
  4. Disconnect the printer/AUX connections where fitted.
  5. Release the panel mounting hardware.
  6. Support the HMI while removing the final fasteners.
  7. Pull the unit straight out of the panel.
  8. Inspect the panel cutout and mounting surface.

The documented panel cutout is 259 × 201 mm. Measure the actual opening rather than assuming the panel was originally cut to specification.

Stage 3: Installing the Replacement — Approximately 10 Minutes

  1. Verify the replacement model: .
  2. Inspect the display and rear connectors.
  3. Confirm the panel opening is suitable.
  4. Position the HMI in the existing cutout.
  5. Install the mounting hardware evenly.
  6. Reconnect the PLC communication wiring.
  7. Reconnect AUX/printer wiring if used.
  8. Check that all connectors are fully seated.
  9. Verify grounding and power wiring.
  10. Keep the original unit available until commissioning is complete.

⚠️ If repl the with a PFXGP4501TAA or PFXGP4501TMA, do not assume that the newer HMI preserves every legacy function. Pro-face confirms the panel cutout compatibility, but the newer units use a TFT color LCD and have different touch/display capabilities.

Stage 4: Power-On & Testing — 5–15 Minutes

  1. Perform a final wiring inspection.
  2. Confirm the correct supply voltage.
  3. Restore power.
  4. Observe the HMI startup sequence.
  5. Verify that the display initializes.
  6. Check touch/operator input.
  7. Verify PLC communication.
  8. Test representative screens.
  9. Check alarms and operator commands.
  10. Test AUX/printer functions if used.
  11. Confirm the machine-control interface before returning the equipment to service.

Frequently Asked Questions (FAQ)

Q1. Isface still manufactured?

No. Pro-face lists the end of sales as July 31, 2000 and end of repair as December 28, 2005. It should be treated as a legacy/obsolete HMI.

Q2. What type of disdoes use?

The is the standard GP-450E model with an EL display and 640 × 400-dot resolution. It is a monochrome-oriented legacy display rather than a modern TFT color HMI.

Q3. Wh the panel cutout size?

The documented panel cutout is 259 × 201 mm. This dimension is important when evaluating a replacement because Pro-face specifically identifies some replacement models as having the same cutout while others require panel modification.

Q4. What software was used tgram ?

Pro-face identifies GP-PROII V3.20 or later as compatible screen-creation software for the GP-450E. A legacy replacement project may therefore depend on recovering the original GP-PROII project rather than simply transferring a modern HMI project.

Q5. What is the recommended replac for ?

Pro-face lists PFXGP4501TAA and PFXGP4501TMA as GP4000 replacement options with the same panel cutout. PFXGP4501TADW is another option, but it has a different panel cutout and requires a DC power supply.

Q6. Can I directllace with PFXGP4501TAA?

Mechanically, the panel cutout is documented as compatible. Electrically and functionally, verify the complete application first. PFXGP4501TAA uses a TFT color LCD and can operate in monochrome mode, but it is a different-generation GP4000 HMI. The PLC protocol, project conversion, communication cable, and operator functions should all be checked before the production changeover.

. Is the same 450-EG11?

No. Pro-face’s documentation lists and as separate models. is specifically documented with the 10-inch EL display and 640 × 400-dot resolution. Do not order based only onGP450 family designation; verify the complete suffix.
