03Features

Design and Functions

  • The high-intensity EL panel provides a monochrome amber interface for industrial operator screens.
  • A 640 x 400 pixel workspace supports legacy GP-PRO/PBIII projects.
  • The matrix touch panel provides 32 x 20 key areas and supports one- or two-point touch operation.
  • Two megabytes of flash screen memory and 96 KB of battery-backed SRAM support project and retained data.
  • The D-sub serial interface supports RS-232C and RS-422 host communication with documented pin assignments.
  • Printer and tool connectors support legacy peripheral and project-transfer workflows.
  • The 24 V DC variant is specifically identified by the -EG41-24VP suffix.

Product Identity

Manufacturer: Pro-face / Digital Electronics

Model: GP477R-EG41-24VP

Product Type: GP-477R Graphic Operator Interface

04Applications

  • Legacy machine and process operator stations.
  • Serial HMI communication with supported PLC and controller families.
  • Installed GP-477R panels requiring the original 640 x 400 amber display format.
  • Maintenance projects that must retain the existing panel cutout and application logic.

05Lifecycle & Replacement

  • The GP-477R is a legacy panel and should be handled as an installed-base product.
  • Pro-face conversion guidance maps GP477R projects to later display families, but display resolution and interface details change.
  • The documented GP3500T conversion expands the display to 640 x 480; screen layout therefore requires review.
  • Newer GP4000 conversion targets require separate validation of serial connectors, cable pinouts, touch behavior, project conversion, and unsupported functions.
  • Archive the original project, communications settings, passwords, screen data, PLC cable details, panel cutout, and power wiring before replacement.

FAQFrequently Asked Questions

What is

GP477R-EG41-24VP is a 24 V DC GP-477R graphic control panel with an amber electroluminescent display.

Which system or application is it designed for?

It is designed for legacy Pro-face GP-PRO/PBIII projects and supported serial PLC or controller connections.

What must be matched before ordering?

Match the complete model or article number, installed hardware revision, electrical ratings, interfaces, wiring, approvals, and project configuration.

What information should be recorded before replacement?

Record the project file, screen fonts, PLC driver, communication protocol, baud rate, D-sub pinout, cable part, panel cutout, supply wiring, and retained data.

How should lifecycle or migration be handled?

Use Pro-face conversion guidance as an engineering starting point; later panels change resolution, connectors, touch behavior, and supported functions.

What should be checked after installation?

Verify power, grounding, serial communication, every screen, every touch target, alarms, retained values, and operator procedures before returning the machine to service.
