2711-K3A10L1 PanelView 300 Keypad Operator Terminal | Allen Bradley

Product Overview

The Allen Bradley 2711-K3A10L1 functions as a compact, rugged Human Machine Interface (HMI) within the PanelView 300 Standard series. It provides a specialized interface for machine-level control, utilizing a monochrome transflective LCD to ensure high visibility even in varied lighting conditions. This terminal integrates directly into DeviceNet networks, enabling efficient data exchange with programmable controllers. We offer this unit as 100% Brand New and Original, providing a critical replacement solution for maintaining legacy systems with factory-certified hardware.

Technical Specifications

The 2711-K3A10L1 delivers reliable performance through the following hardware parameters:

Engineering Advantages

The 2711-K3A10L1 addresses specific technical challenges in harsh industrial environments:

• Superior Backlight Longevity: The 100,000-hour LED backlight exceeds standard CCFL lifespans. This ensures the display remains bright and readable for over a decade of continuous operation, significantly reducing maintenance intervals.

• Tactile Feedback for Gloved Operation: The stainless-steel domed keys provide clear tactile feedback. This design allows operators to navigate menus and enter numeric data accurately while wearing heavy industrial gloves, a common limitation of touchscreen models.

• Robust Environmental Sealing: Carrying NEMA 4X and IP65 ratings, the front bezel resists high-pressure washdowns, oil, and corrosive debris. This enables installation in food processing or metalworking environments where contaminants are prevalent.

• Integrated Network Diagnostics: Two dedicated status indicators (Green for COMM, Red for Fault) provide instant visual confirmation of network health. Engineers troubleshoot connectivity issues at a glance without needing to bridge into the DeviceNet trunk.

FAQs

• How do I connect this terminal to a PC for programming?

  You require the 1761-CBL-PM02 communication cable and PanelBuilder32 software. While the unit communicates via DeviceNet on the plant floor, the RS-232 port facilitates local configuration and application uploads.

• Can this model replace an older 2711-K3A5L1 (DH-485) unit?

  Physically, the units fit the same panel cutout. However, since the 2711-K3A10L1 utilizes the DeviceNet protocol, you must update your network architecture and PLC communication logic to accommodate the shift from DH-485 to DeviceNet.

• What is the significance of the "Transflective" display?

  Transflective technology uses both backlighting and ambient light. In bright environments, the display reflects ambient light to increase contrast, whereas in dark areas, the LED backlight provides the necessary illumination. This prevents the "washout" effect common in standard LCDs.

• Does the 240 KB memory limit the complexity of my screens?

  The memory specifically holds application objects, text, and bitmaps. By using simple vector graphics rather than high-resolution bitmaps, you can maximize this space to support dozens of functional control screens and alarm summaries.
