Allen Bradley 2711-M3A19L1 PanelView 300 Micro Operator Interface

Product Introduction

The Allen-Bradley 2711-M3A19L1 PanelView 300 Micro Operator Interface is a compact and dependable HMI designed for industrial applications requiring precise operator control and integration with legacy PLC systems. This model is part of the PanelView 300 series and provides a 3-inch monochrome display with DH-485 communication, making it suitable for monitoring and controlling small-scale automation systems.

Equipped with an 8-pin mini-DIN connector for RS-232 (DH-485) communication, the 2711-M3A19L1 interfaces seamlessly with Allen-Bradley PLC-5 and SLC controllers. The 24 VDC power input makes it compatible with standard industrial power setups, and its small size allows installation in limited-space control panels. Despite its compact design, it provides clear visualization of process data, alarm notifications, and system status, supporting efficient operation and quick decision-making in industrial environments.
