Allen Bradley 2711P-K4M20D PanelView Plus 400 Graphic Terminal

Product Overview

The Allen Bradley 2711P-K4M20D functions as a compact, rugged Human-Machine Interface (HMI) within the PanelView Plus 400 family. This terminal provides essential visualization and control for small-scale automation applications, utilizing a 3.8-inch grayscale display and a high-tactile keypad. Although the manufacturer classifies this series as discontinued, we supply this unit as 100% Brand New and Original, allowing engineers to maintain existing control systems without the high cost of migrating to newer hardware platforms.

Part Number Breakdown

The 2711P-K4M20D nomenclature identifies its specific hardware configuration:

• 2711P: PanelView Plus Series platform.

• K: Keypad input (Numeric and Navigation keys).

• 4: 400 Series (3.8-inch display size).

• M: Grayscale (Monochrome) FSTN display type.

• 20: Combined Ethernet and RS-232 communication ports.

• D: 18–30V DC input power (Nominal 24V DC).

Technical Specifications

The following data outlines the mechanical and electrical characteristics of the terminal:

Engineering Advantages

• Optimized for Harsh Environments: The grayscale FSTN display remains legible across a wide range of lighting conditions and temperatures. Unlike touchscreens, the physical keypad ensures reliable input even when operators wear heavy industrial gloves or work in greasy environments.

• Integrated Communication Hub: Dual onboard ports (Ethernet and RS-232) facilitate simultaneous connection to modern high-speed networks and legacy serial-based PLCs. This versatility simplifies data bridging between different generations of automation hardware.

• Compact Footprint Mounting: The slim design and DC power requirement make this unit ideal for small control consoles or machine-mounted enclosures where space and thermal dissipation are limited.

• Low-Latency Data Refresh: The 320 x 240 resolution paired with 64MB of memory ensures rapid screen transitions and real-time updates of critical process variables, preventing display lag during fast-cycle operations.

FAQs

• Does the 2711P-K4M20D support USB peripherals?

  Yes. The terminal includes two USB host ports. These ports support the connection of keyboards, mice, or external flash drives for easy data logging and project transfers.

• How do I replace a failed unit without losing my application?

  You can transfer the existing .MER runtime file via the RS-232 port or a compatible memory card. Since this unit is Brand New, it arrives with a factory-clean OS, ready for your specific application load.

• What is the primary benefit of the keypad over a touchscreen for this model?

  The navigation keys provide an actuating lifespan of 1 million presses and require a 340g operating force. This mechanical feedback prevents accidental triggers and provides a more durable interface for high-vibration machinery.

• Can I use this model on an AC power circuit?

  No. This unit requires a DC input between 18V and 30V. Connecting this terminal to an AC power source will cause immediate hardware damage.
