Allen-Bradley 2711-K5A1 PanelView 550 Keypad Terminal HMI

Allen-Bradley 2711-K5A1 PanelView 550 Keypad Terminal HMI is a PanelView Standard operator terminal that combines a 5.5-inch monochrome display with a dedicated keypad for local input and navigation. The keypad-enabled 2711-K5A1 variant supports Remote I/O communication and includes an RS-232 printer port for printing alarms, trends, or process data from the PLC. This device is part of the PanelView 550 family, a compact operator interface used on PLC-controlled equipment in industrial settings. Firmware revision FRN 1.03 is documented for this model, reflecting its legacy PanelView 550 software level. Typically powered from an AC supply and designed to mount in control panels or machine enclosures, the 2711-K5A1 provides a rugged, button-driven HMI that displays status information and prompts operators to enter data or execute commands. Common applications include small to mid-size manufacturing lines, packaging machines, and process-control stations where a durable, non-touch interface is preferred over a touchscreen.
