Product Introduction
The Allen-Bradley 2711-M3A18L1 PanelView 300 Micro Operator Interface is a compact and reliable HMI designed for industrial applications requiring precise operator control in a small form factor. As part of the PanelView 300 series, this model offers a 3-inch monochrome display and RS-232 (DF1) communication, making it ideal for systems where space is limited but accurate process monitoring and control are required.
The interface supports DF1 communication through an 8-pin mini-DIN connector, allowing seamless integration with Allen-Bradley MicroLogix and SLC controllers. Powered by 24 VDC, it fits standard industrial power setups and can be used in both new installations and system retrofits. Despite its small size, it provides clear visualization of process data, system status, and alarm conditions, helping operators maintain efficient workflow.
