Allen Bradley 2711-B5A5 PanelView 550 Operator Interface

Product Introduction

The Allen-Bradley 2711-B5A5 PanelView 550 Operator Interface is a versatile and durable HMI terminal designed for industrial automation systems requiring stable operator interaction and clear process visualization. As a member of the PanelView 550 family, this model integrates both keypad and touchscreen input, offering flexible control methods for different operating conditions.

Equipped with a 5.5-inch monochrome display, the unit provides reliable performance for text-based monitoring and simple graphical interfaces. The 256 × 128 pixel resolution ensures fast screen refresh and efficient data presentation, making it suitable for applications where clarity and responsiveness are more critical than complex graphics.

This model supports RS-232 (DH-485) communication, allowing seamless integration with legacy Allen-Bradley PLC platforms such as SLC 500 and MicroLogix systems. Unlike DC-powered variants, the 2711-B5A5 operates on a wide-range 100–240 VAC power supply, making it adaptable to different industrial power environments without requiring additional converters.

With its robust construction and proven reliability, this operator interface is widely applied in manufacturing, processing, and machine control systems where long-term stability and ease of use are essential.
