Allen-Bradley 2711P-K4M20A Grayscale Keypad HMI Terminal – PanelView Plus 400 Series
When a critical HMI terminal fails on the production floor, the consequences are immediate: lines stop, operators lose visibility into process parameters, and every minute of downtime translates directly into lost output and escalating maintenance costs. In environments where split-second decisions depend on reliable human-machine interface access — from automotive assembly to water treatment — the absence of a dependable operator panel is not a minor inconvenience. It is a production crisis. The Allen-Bradley 2711P-K4M20A was engineered precisely to eliminate that vulnerability.
Within the PanelView Plus 400 family, the 2711P-K4M20A occupies the entry-level keypad position — purpose-built for applications where a compact, rugged, and cost-effective HMI is required without sacrificing Rockwell Automation’s proven FactoryTalk View ME platform compatibility. Globally, PanelView Plus terminals are deployed across hundreds of thousands of machines in over 80 countries, making the 2711P-K4M20A one of the most widely recognized compact HMI solutions in industrial automation.
