Description

The Allen-Bradley 2711-B5A3L1 is a PanelView 550 operator terminal designed for reliable human-machine interface (HMI) applications in industrial environments. This DC-powered unit serves as a critical control interface, allowing operators to monitor system variables, execute manual commands, and manage automated processes. Built for durability, the terminal replaces complex physical pushbutton arrays with a consolidated electronic interface, reducing wiring requirements and enhancing system uptime in sectors such as petrochemical, water treatment, and automated packaging.

Features

Hybrid input configuration featuring both an analog resistive touchscreen and a 10-key tactile function keypad (F1-F10).
5.5-inch monochrome blue-mode LCD display with 256 x 128 pixel resolution.
Integrated DH-485 communication port for multi-node network connectivity.
Dedicated RS-232 serial port for local printer data logging.
170 KB of application runtime memory with non-volatile storage for screen data.
Field-replaceable backlight module (2711-NL1) to extend operational life.

Applications

This operator terminal is suitable for a wide range of industrial automation tasks, including machine control, process monitoring, and data logging in manufacturing facilities. Its robust design allows for operation in high-vibration environments where traditional mechanical interfaces might fail.
