2711P-K4M20D8 | Allen-Bradley PanelView Plus 6 400 Grayscale Keypad Terminal

Product Overview

The Allen-Bradley 2711P-K4M20D8 functions as a compact, high-efficiency operator interface within the PanelView Plus 6 400 family. This terminal features a 3.5-inch Grayscale TFT LCD, providing sharp 320 x 240 resolution with 16 levels of gray for clear process visualization. It utilizes a rugged tactile keypad with 8 dedicated function keys (F1–F8) to ensure precise operator input in demanding factory environments. We supply this unit in 100% Brand New condition, offering a reliable, factory-fresh solution for maintaining existing systems that require specific monochrome display parameters and DC power.

Engineering Advantages

The 2711P-K4M20D8 addresses specific operational challenges in industrial automation through its hardened hardware profile:

• Tactile Reliability in Harsh Zones: The mechanical keypad provides physical feedback that touchscreens cannot match. This allows operators to execute commands accurately while wearing heavy industrial gloves or working in areas where screen contaminants (like grease or moisture) might interfere with capacitive touch sensitivity.

• Dual-Protocol Communication: Integrated Ethernet and RS-232 ports allow the terminal to communicate with modern Logix controllers and legacy SLC or PLC-5 systems simultaneously. This eliminates the need for external protocol converters, simplifying the network architecture.

• Efficient Power Design for Mobile/Remote Racks: The 18–30V DC input range accommodates standard industrial battery systems and 24V DC power supplies. This low-voltage requirement reduces heat generation within small enclosures and ensures compatibility with remote solar-powered or mobile equipment.

• Modernized Performance for Legacy Footprints: While maintaining a compact 3.5-inch form factor, the PanelView Plus 6 internal architecture provides significantly faster processor speeds and larger memory capacity compared to original PanelView Standard units. This allows for more complex alarm handling and faster screen transitions without changing the panel cutout.

FAQs

• Can the 2711P-K4M20D8 communicate with an SLC 500 controller?

  Yes. You can use the integrated RS-232 port with a 2711-NC13 cable to establish DH-485 or DF1 communications, or utilize the Ethernet port if your SLC 500 uses an Ethernet interface (like the SLC 5/05).

• Is the LED backlight in this model replaceable?

  The 2711P-K4M20D8 utilizes a long-life White LED backlight that the manufacturer designs as non-replaceable. Because we provide these units as 100% Brand New, you receive the full 25,000-hour minimum service life from the moment of installation.

• Does this model support color graphics?

  No. The 2711P-K4M20D8 features a Grayscale (Monochrome) TFT display. This model is ideal for applications where high-contrast text and simple status indicators are more important than complex color mapping.

• What software do I need to program this terminal?

  You program the 2711P-K4M20D8 using FactoryTalk View Studio Machine Edition (ME) software. The 256 MB of RAM ensures the module handles modern firmware revisions smoothly.
