Description
The Allen-Bradley 2711-K5A15L2 is a robust industrial human-machine interface (HMI) terminal from the PanelView Standard series, engineered for reliable command and diagnostic monitoring in demanding industrial environments. This unit is specifically designed for applications requiring high-durability input methods, such as automotive assembly, material handling, and wastewater treatment facilities. Featuring a 5.5-inch monochrome LCD and a tactile mechanical keypad, the terminal provides operators with clear visibility of process loops, machine status, and alarm conditions, facilitating rapid response and reduced downtime.
Features
-
Rugged Interface: Tactile mechanical keypad with numeric matrix and F1-F10 function keys, ideal for high-vibration environments where touchscreens may be impractical.
-
Deterministic Communication: Integrated ControlNet port for high-speed, time-critical data exchange with host programmable logic controllers.
-
Diagnostic Support: Dedicated RS-232 printer port for generating hardcopy fault summaries, sequence logs, and diagnostic reports.
-
Industrial Power Design: Operates on 100-240 VAC with integrated line filtering to mitigate electromagnetic interference and grid fluctuations.
-
Compact Display: 5.5-inch blue monochrome LCD with 256 x 128 pixel resolution for clear, high-contrast process visualization.
Applications
This operator terminal is suited for legacy automation systems where deterministic communication and physical keypad input are required. Typical applications include:
- Automotive assembly lines
- Material handling and conveyor control
- Wastewater treatment process monitoring
- Localized machine diagnostics and alarm management

-
Grounding: Always connect the chassis ground terminal to a low-impedance earth ground to prevent electrical noise interference and ensure operator safety.
-
Power Wiring: Verify that the input voltage matches the 100-240 VAC specification before applying power. Use shielded cables for communication lines to minimize EMI.
-
Handling: This device contains sensitive electronic components. Handle with care and ensure the power is disconnected before performing any wiring or maintenance.
-
Cooling: Maintain adequate clearance around the unit to ensure proper airflow and prevent overheating during continuous operation.
FAQ
Is the 2711-K5A15L2 compatible with modern Ethernet networks?
No, this specific model is designed for ControlNet communication. It does not support native Ethernet/IP connectivity.
Can this unit replace a touchscreen model?
This unit is designed for applications requiring a mechanical keypad. While it can replace other PanelView Standard units, ensure your application logic supports the specific ControlNet communication protocol used by this model.
What is the primary purpose of the RS-232 port?
The RS-232 port on this model is configured as a dedicated printer port for outputting diagnostic logs and fault history, rather than for general-purpose PLC communication.
