Allen-Bradley 2711-K3A10L1 PanelView 300 HMI Terminal

Allen-Bradley 2711-K3A10L1 PanelView 300 Standard Operator Terminal is a compact 3-inch monochrome HMI with a keypad designed for direct operator interaction with Allen‑Bradley PLCs. It provides DeviceNet communications and an RS-232 printer port for serial data exchange, and it operates from a DC power supply (11–30 V DC input, 24 V nominal). The PanelView 300 Standard family, including this model, stores about 170 KB of application runtime memory and 240 KB of nonvolatile memory for objects, text, and bitmaps, enabling text‑based displays and simple graphics on the factory floor. This terminal is intended for use as a dedicated operator interface in machine panels where a rugged, standalone HMI with tactile input is required.
