Product Overview

The Allen-Bradley 2711-B5A8L3 is a robust operator terminal from the PanelView 550 series, designed to provide reliable human-machine interface (HMI) capabilities in demanding industrial environments. This unit features a hybrid input design, combining a resistive touchscreen with a tactile keypad, allowing for versatile control and monitoring of automated processes. It is engineered for long-term deployment in sectors such as water treatment, chemical processing, and automated manufacturing, where it serves to streamline operator interaction and reduce system downtime.

Hardware Features

The 2711-B5A8L3 utilizes a 5.5-inch monochrome blue-mode LCD display, offering a clear 256 x 128 pixel resolution suitable for process visualization. The input system includes 10 dedicated function keys (F1-F10) alongside a touchscreen matrix with 128 active cells, ensuring operational reliability even in high-vibration settings. For networking and data management, the terminal is equipped with a Data Highway Plus (DH+) communication port for deterministic plant-floor connectivity and an RS-232 serial port for local printer logging.

Installation Guidelines

  • Ensure the panel cutout is prepared according to the manufacturer's mounting specifications to maintain the NEMA/IP rating of the enclosure.
  • Verify that the DC power supply is within the 18-32 VDC range before connection to prevent damage to the internal circuitry.
  • Use shielded cables for DH+ and RS-232 communications to minimize electromagnetic interference (EMI) in high-noise industrial areas.
  • Always power down the terminal before connecting or disconnecting communication cables or performing maintenance.
  • Handle the unit with care to avoid damage to the resistive touchscreen overlay and the LCD backlight assembly.
