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.
