The Allen Bradley 2711-M3A19L1 PanelView 300 Micro is a compact industrial Human Machine Interface (HMI) engineered for simple operator control, machine monitoring, and basic process visualization in legacy automation systems. As part of the PanelView 300 Micro series, this terminal is optimized for minimal panel space while maintaining reliable communication with Allen-Bradley PLC systems.
Built for straightforward industrial applications, the 2711-M3A19L1 combines a small monochrome display with a durable keypad interface, making it ideal for machines where only essential runtime interaction is required. It is widely used in OEM equipment, small production machines, and legacy control systems that rely on DH-485 communication.
Despite its compact size, the unit remains a stable and proven solution in long-life industrial installations where simplicity and reliability matter more than advanced visualization.
