The Allen-Bradley 2711-B5A8L1 is a PanelView 550 operator terminal designed for reliable human-machine interface (HMI) applications. This DC-powered unit provides real-time process monitoring, alarm management, and operator control in demanding industrial environments such as chemical processing, oil and gas, and water treatment facilities.

Features

  • Hybrid input interface featuring both an analog resistive touchscreen and a 10-key tactile function keypad (F1 to F10).
  • 5.5-inch monochrome blue-mode LCD display with 256 x 128 pixel resolution.
  • Integrated Data Highway Plus (DH+) communication port for deterministic plant-floor networking.
  • Dedicated RS-232 serial port for local printer connectivity.
  • Long-life LED backlight rated for 100,000 hours of operation.
  • Dual-memory architecture with 170 KB for application runtime and 240 KB for nonvolatile storage.

Applications

This terminal is suitable for industrial automation tasks requiring robust HMI functionality, including machine control, process visualization, and alarm annunciation in environments where high-vibration or harsh conditions necessitate physical keypad input options.
