Description

The Allen-Bradley 2711-B5A8L2 is a high-reliability operator terminal within the PanelView 550 Standard product line. This DC-powered human-machine interface (HMI) is designed for real-time process monitoring, alarm data management, and manual control input in demanding industrial environments. It is suitable for applications in oil and gas, chemical processing, water management, and automated packaging, offering a consolidated electronic interface that replaces traditional hardwired pushbuttons.

Features

  • Hybrid input mechanism featuring both a resistive touchscreen and a 10-key mechanical function keypad (F1-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 data logging.
  • Solid-state 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 engineered for continuous deployment in severe industrial settings where reliable HMI performance is critical for maintaining operational throughput and reducing unscheduled downtime.
