Allen-Bradley 2711-K9A1 PanelView Human Machine Interface

Allen-Bradley 2711-K9A1 PanelView 900 Standard Operator Terminal is a 9-inch monochrome HMI designed to sit at the machine front as the operator’s window into a Rockwell Automation PLC. This PanelView 900 model uses a physical keypad for input and a 9-inch display suitable for text, alarms, and simple graphics, delivering reliable local control and visibility on industrial equipment. It provides RS-232 communication alongside a Remote I/O (RIO) interface, enabling direct connections to Allen-Bradley PLCs and integration with existing PanelView 900 networks without requiring a touchscreen. The unit is powered from 100–240 VAC, making it compatible with common European and North American power systems, and it remains a compact, rugged Terminal within the PanelView 900 family for legacy lines or distributed control applications. Typical use cases include displaying real-time process status, enabling operator input via the keypad, acknowledging alarms, and navigating basic operator screens to interact with PLC logic on small to mid-size manufacturing or packaging equipment. This terminal is suited for environments where a non-touch, keypad-driven interface is appropriate and where compatibility with RS-232 and Remote I/O communications is required to interface with existing Rockwell Automation control architectures.
