Description

The Allen-Bradley 2711-B5A3 is a PanelView 550 operator terminal designed for reliable human-machine interface (HMI) applications in industrial environments. This AC-powered unit provides a robust interface for monitoring and controlling automated processes, combining both physical keypad inputs and a touchscreen for versatile operator interaction. It is engineered to withstand demanding conditions in sectors such as water treatment, petrochemical processing, and manufacturing, ensuring consistent communication with PLC systems via the DH-485 network protocol.

Features

  • Hybrid input interface featuring 10 mechanical function keys (F1-F10) and a resistive touchscreen with 128 active cells.
  • 5.5-inch monochrome blue-mode LCD display with 256 x 128 pixel resolution.
  • Integrated DH-485 communication port for multi-node network connectivity.
  • Dedicated RS-232 serial port for local printer support and data logging.
  • Nonvolatile application memory (up to 240 KB on Series E and later).
  • Supports external storage via an ATA memory card slot.
  • Long-life LED backlight rated for 100,000 hours.

Applications

The 2711-B5A3 is suitable for a wide range of industrial automation tasks, including machine control, process visualization, and alarm management. It is commonly deployed in systems requiring a compact, NEMA-rated interface for harsh environments where high-vibration or moisture resistance is necessary.
