Allen-Bradley 2711-K5A20 HMI Panel Display Terminal

Allen-Bradley 2711-K5A20 PanelView 550 is a monochrome, keypad-operated HMI terminal designed for PanelView Standard PV550 applications. It features a 5.5-inch display and is powered from an AC power terminal. It provides an Ethernet port for network data exchange and an RS232 printer port for hard-copy reporting, enabling operators to view screens and input commands on PLC-based processes. This model belongs to Rockwell Automation's PanelView 550 family, a legacy line of operator terminals that delivers local visualization, alarms, and basic process control on the factory floor. Typical deployments include machine- or line-level HMIs that connect to Allen-Bradley controllers via the built-in Ethernet and serial interfaces, facilitating straightforward monitoring and control without a separate computer. The 2711-K5A20 designation identifies a PanelView 550 keypad terminal with Ethernet connectivity and RS232 printer capabilities in a compact 5.5-inch form factor.
