Allen-Bradley 2711P-K4M20A8 PanelView Plus 6 Terminal

Technical Specifications Breakdown

Key parameters for the 2711P-K4M20A8 are listed below for quick reference:

Industry Applications

Small Packaging Lines

In a compact packaging machine, the 2711P-K4M20A8 provides a cost-effective operator interface. Operators use the keypad to start/stop cycles, set parameters, and view production counts. The Ethernet port connects to a PLC for real-time data exchange, while the RS-232 port can link to a barcode scanner or printer.

Machine Tool Control

For small CNC or manual machine tools, this HMI offers reliable control. The grayscale display shows tool offsets and status messages clearly. The function keys can be programmed for quick access to common operations, reducing training time.

Building Automation

In HVAC or lighting control panels, the 2711P-K4M20A8 serves as a local monitoring point. Its compact size fits into standard electrical enclosures. The Ethernet/IP connectivity allows integration with building management systems.

Installation & Setup Guidance

Mount the terminal in a panel cutout that matches the display area. Ensure adequate clearance for ventilation and cable connections. Connect the input power to a 100 to 240V AC, 50 to 60 Hz source. Use the Ethernet port (RJ45, 10/100Base-T) to connect to your network. The RS-232 port can be used for serial communication. The USB host port supports an USB flash drive for data transfer. The USB device port allows connection to a PC for programming.

Maintenance & Reliability

The 2711P-K4M20A8 is designed for long service life. The backlight is a white LED with a minimum life of 25,000 hours at 25 °C (77 °F). This backlight is not replaceable, so plan for eventual replacement of the unit. The battery-backed clock maintains accurate time (±2 minutes per month) and the battery lasts up to 4 years at 25 °C. The battery is field replaceable with catalog number 2711P-RY2032 or any equivalent CR2032 coin-cell lithium battery. Periodically inspect the terminal for dust accumulation and ensure proper ventilation.

Compact HMI Power for Small Automation

This PanelView Plus 6 terminal packs essential visualization and control into a compact 3.5-inch package. It is built for micro and small automation applications where space is tight but performance cannot be compromised.

This HMI features a grayscale TFT LCD display with a resolution of 320 x 240 and 16 levels of gray. The 8 function keys (F1…F8), numeric input, and navigation keys provide precise operator control. With 256 MB RAM and 512 MB nonvolatile memory (approx. 73 MB free user memory), the terminal handles your application screens and data logging efficiently.

Compatibility & Integration

The 2711P-K4M20A8 communicates via Ethernet (10/100 Mbps, Auto-MDI/MDI-X) and RS-232. It supports EtherNet/IP, an open industrial network for real-time I/O messaging. The Ethernet port also supports application transfers and printing. If additional Ethernet ports are needed for larger terminals (700 to 1500), the 2711P-RN20 module is available, but this is not applicable to the 400 series. The USB ports allow connection of a keyboard or storage devices.
