Allen-Bradley 2711-K3A5L1 Panel View 300 HMI Terminal

Allen-Bradley 2711-K3A5L1 PanelView 300 Monochrome HMI Terminal is a compact, keypad-based operator interface from the PanelView Standard family (Series A) that runs on 24V DC power and communicates via RS-232 DH-485. It features a 3-inch monochrome display, a built-in keypad for local control, an RS-232 DH-485 data port, and a dedicated RS-232 printer port for hard-copy reporting. The terminal provides 240 KB of nonvolatile memory and 170 KB of RAM for running operator applications, making it suitable for small front-end panels on machines like conveyors or packaging lines that connect to Allen-Bradley PLCs over DH-485. With its rugged keypad input and compact form factor, it serves as a reliable non-touch HMI when simple, space-efficient operation is required.
