Description
⚙️ Product Introduction
The Allen-Bradley 2711-K5A20 is a PanelView 550 Standard Operator Terminal designed for industrial machine control, process monitoring, and operator interface applications. It combines a monochrome LCD display with a physical keypad and EtherNet/IP communication, making it suitable for systems where operators need direct access to PLC data, alarms, parameters, and machine functions.
The 2711-K5A20 uses a 5.5-inch monochrome LCD with a 256 × 128 resolution and a 120 × 60 mm viewing area. The keypad provides F1–F10 function keys, navigation keys, and operator-entry controls. The keypad construction uses a stainless-steel domed membrane design intended for repeated industrial operation.
🔧 Communication is provided through EtherNet/IP, with an additional RS-232 printer interface. The terminal supports PanelBuilder32 for application development and transfer, while its application memory architecture includes approximately 170 KB of runtime memory and 240 KB of nonvolatile RAM.
The AC-powered 2711-K5A20 accepts 85–264 VAC, 47–63 Hz, with maximum AC power consumption specified at approximately 45 VA. The terminal is approximately 167 × 266 × 106 mm and weighs about 1.2 kg according to Rockwell Automation documentation.

🛠️ Application & Integration
The 2711-K5A20 is intended for use as an operator interface between personnel and industrial control equipment. Typical applications include PLC-based machine control, production equipment, material handling systems, packaging machinery, process equipment, and industrial automation panels.
For an existing EtherNet/IP installation, the terminal can provide operator access to PLC variables, status information, alarms, setpoints, and control commands. Before replacement, confirm the existing PanelView catalog number, communication protocol, power configuration, application file, firmware requirements, and PLC communication settings.
Because the PanelView 550 family contains multiple communication variants, the 2711-K5A20 should not be treated as interchangeable with DH-485, DH+, DeviceNet, ControlNet, or Remote I/O versions without checking the complete system architecture. Rockwell documentation specifically identifies the K5A20 as the EtherNet/IP version.
❓ FAQ
