Overview
The Schneider Electric GP477R-EG11 is a Pro-face operator interface panel designed for industrial automation and process control applications. Built into the GP477R/577R series, this 8.9-inch monochrome HMI delivers reliable operator feedback through a high-intensity amber EL display. Although discontinued by Schneider Electric (end of sales June 2009), this legacy unit remains widely installed in manufacturing facilities and is available as new surplus stock for system replacement, retrofit, and maintenance inventory.
Key Features
- 8.9-inch amber monochrome EL display — high-intensity output with improved readability in industrial environments
- Dual brightness levels — adjustable display brightness for ambient light conditions
- 2MB Flash + 96KB backup memory — sufficient capacity for complex HMI applications
- Expandable character display — character size up to 8x enlargement; supports ASCII, Chinese (simplified), Korean Hangul, and Japanese fonts
- Internal clock — ±65 seconds/month accuracy at room temperature
- AC power supply — 50/60 Hz, AC85V–132V rated input; <50VA power consumption
- Serial communications — RS232C/RS422 asynchronous connections; supports multiple PLC/device protocols via optional interface modules
- Compact design — fits standard 8″ QuickPanel mounting cutouts compatible with GP4000 series panel dimensions

Replaces / Drop-In Replacement For
The GP477R-EG11 is a legacy unit. For direct replacements with same mechanical fit (panel cut-out dimensions), Schneider Electric recommends:
- PFXGP4501TAA — GP4000 series TFT color LCD, AC power supply, same panel cut-out size
- PFXGP4501TMA — GP4000 series TFT color LCD with 2-point touch, AC power supply
Note: Newer replacement models (e.g., PFXGP4501TADWF0C) require power supply and mechanical adaptation. Verify compatibility with your system integrator before ordering, as panel dimensions and electrical requirements may differ.
