Description

The Allen-Bradley 2711-B5A5L1 is a PanelView 550 operator terminal designed for reliable human-machine interface (HMI) applications in industrial environments. This DC-powered unit facilitates real-time process monitoring, alarm logging, and operator control by communicating with programmable logic controllers (PLCs). Engineered for demanding settings such as water treatment, food packaging, and chemical processing, the terminal provides a robust interface that helps minimize downtime and improve system reliability.

Features

Hybrid input system featuring both an analog resistive touchscreen and a 10-key mechanical function keypad (F1 to F10) for operation in high-vibration environments.
5.5-inch monochrome blue-mode LCD display with a 256 x 128 pixel resolution.
Integrated RS-232 communication port supporting DH-485 protocol for connectivity with SLC 500 and MicroLogix controllers.
Internal 170 KB application runtime memory with nonvolatile storage for screen and font data.
Field-replaceable backlight module (2711-NL1) to extend service life.

Applications

This terminal is suitable for various industrial automation tasks, including local machine control, status monitoring, and alarm management in manufacturing and process control facilities. It is compatible with standard DH-485 network architectures.
