The 2711-K5A20L1 is a compact, DC-powered human-machine interface (HMI) unit belonging to the Allen-Bradley PanelView 550 Standard series. Designed for robust machine-level visualization, this terminal facilitates real-time process monitoring and direct interaction with programmable logic controllers (PLCs). It is engineered for 24 VDC industrial environments, providing a reliable alternative to traditional physical switch panels in applications such as automotive assembly, water processing, and material handling.

Communication and Memory

This unit features a dual-interface architecture to support both network connectivity and peripheral logging. The primary communication port is an integrated Ethernet interface, enabling low-latency data exchange over EtherNet/IP architectures. A secondary RS-232 serial port is provided for dedicated printer output or firmware updates. The terminal includes 170 KB of application runtime RAM and 240 KB of non-volatile memory, with an integrated PCMCIA ATA slot available for expanded storage, recipe management, and data logging.

Features

  • Integrated membrane keypad with 10 assignable function keys (F1-F10), numeric input, and navigation clusters.
  • 5.5-inch monochrome transflective LCD (blue mode) with long-life LED backlight.
  • Field-serviceable backlight (MTBF 100,000 hours).
  • Hardware-based real-time clock (RTC) for precise event time-stamping.
  • Status diagnostics via dedicated COMM (green) and Fault (red) LEDs.
  • NEMA 12, 13, 4X and IP54/IP65 environmental ratings for indoor industrial use.
