The Allen-Bradley 2711-K5A9L1 is a PanelView 550 series operator terminal designed for reliable human-machine interface (HMI) control in industrial automation environments. This unit provides a robust solution for monitoring and managing machine operations through a 5.5-inch monochrome blue-mode LCD display and a tactile 10-key keypad input, facilitating efficient interaction with legacy PLC and SLC control systems.

Features

• 5.5-inch monochrome blue-mode LCD display for clear status visualization.
• Integrated 10-key keypad (F1-F10) for direct operator input and control.
• 170 KB of internal application runtime memory.
• Supports RS-232 (DH-485) communication for seamless integration with Allen-Bradley controllers.
• Dedicated RS-232 printer port for local data logging and reporting.

Applications

This terminal is suitable for industrial applications requiring direct serial communication with PLC and SLC controllers. It is commonly utilized in legacy manufacturing environments for process monitoring, alarm management, and system configuration.

Installation Guidelines

• Ensure the terminal is mounted in a panel or enclosure that provides adequate protection against environmental contaminants.
• Verify that the supply voltage is 24 VDC and correctly polarized before connecting to the power terminals.
• Use shielded communication cables for RS-232 connections to minimize electromagnetic interference (EMI) from high-voltage equipment.
• Maintain proper ventilation around the unit to ensure the operating temperature remains within the 0 to 55 degC range.
• Always disconnect power before performing any wiring or maintenance tasks on the terminal.
