Applications
• Legacy machine control and operator monitoring systems in industrial automation
Widely used in older production lines where basic HMI visualization and control functions are required.
• Packaging and material handling equipment with simple operator interaction needs
Provides essential status display and manual input functions for straightforward machine operation.
• Process equipment requiring real-time parameter adjustment and alarm monitoring
Enables operators to view system status and adjust key process variables directly on the panel.
• OEM machinery with DH-485 or RS-232 based control architecture
Integrates into legacy Allen-Bradley PLC environments using serial communication protocols.
Key Advantages
• Compact monochrome display with clear industrial readability
Designed for reliable visibility in harsh factory environments with long backlight life.
• Physical keypad interface with function keys for direct operation
Allows fast machine interaction without reliance on touchscreen input.
• Stable RS-232 (DH-485) communication for legacy PLC integration
Ensures compatibility with older Allen-Bradley control systems.
• Industrial-grade enclosure suitable for panel mounting environments
Built to withstand continuous operation in demanding production conditions.
