Description

The Allen-Bradley 2711-B5A3L3 is a PanelView 550 operator interface terminal designed for rugged industrial environments. This unit provides a robust human-machine interface (HMI) for real-time process monitoring, alarm logging, and manual control inputs. It communicates directly with programmable logic controllers (PLCs) to facilitate data exchange and system management. Built for demanding applications such as chemical processing, water treatment, and food packaging, this terminal features a durable design that minimizes downtime and ensures reliable operation in harsh conditions.

Features

Hybrid input system featuring both an analog resistive touchscreen (128 active cells) and a 10-key mechanical function keypad.
5.5-inch monochrome blue-mode LCD display with 256 x 128 pixel resolution.
Integrated DH-485 communication port for seamless connectivity with SLC 500 and MicroLogix controller architectures.
Dedicated RS-232 serial port for local printer data logging.
Non-volatile memory storage with support for external ATA memory cards.
Long-life LED backlight rated for 100,000 hours of operation.
Battery-backed real-time clock for accurate event timestamping.

Applications

This operator terminal is suitable for a wide range of industrial automation tasks, including:

Process monitoring in petroleum and chemical refineries.
Machine control in food and beverage packaging lines.
System status visualization for water and wastewater treatment facilities.
Local operator control and data logging for PLC-based automation systems.
