Allen Bradley 2711-B5A8 PanelView 550 Operator Interface

Product Introduction

The Allen-Bradley 2711-B5A8 PanelView 550 Operator Interface is a rugged industrial HMI designed for reliable operator control and monitoring in automation systems. As part of the PanelView 550 series, this model supports both keypad and touchscreen operation, providing flexible interaction methods for different industrial environments.

It features a 5.5-inch monochrome LCD display with 256 × 128 pixel resolution, optimized for clear text presentation and basic graphical interface elements. The display design emphasizes stability and readability, making it suitable for continuous industrial operation rather than complex visualization tasks.

This version is equipped with DH+ and RS-232 communication interfaces, enabling integration with a broader range of Allen-Bradley PLC systems, especially in legacy plant architectures. The wide-range 100–240 VAC power input allows direct connection to standard industrial AC power systems, improving installation flexibility.

With its compact structure, proven durability, and stable performance, the 2711-B5A8 is widely used in manufacturing, process control, and legacy system maintenance applications.
