Product Overview

The 2711-B5A5 is a PanelView 550 Standard operator terminal from Allen-Bradley, used to provide operator interface in industrial control systems. Featuring a 5.5-inch monochrome blue-mode LCD with both keypad and touchscreen input, it executes HMI applications using SLC-500 or PLC controllers via embedded DH-485 and RS-232 (DF1) serial communications. The terminal is typically panel-mounted and suits applications such as machine/operator interaction, alarm and recipe handling, and data monitoring in factory automation environments. Part number 2711-B5A5 is discontinued but remains in use for maintenance and legacy support.
