Allen-Bradley 2711-K5A1 PanelView 550 Monochrome Keypad Terminal

Product Overview

The Allen-Bradley 2711-K5A1 serves as a robust Human-Machine Interface (HMI) within the PanelView 550 series. This terminal features a 5.3-inch monochrome blue-mode display that provides clear text and graphic visualization for industrial machine control. It utilizes a durable tactile keypad for operator input and supports high-speed Remote I/O (RIO) communications for seamless PLC integration. We supply this unit in 100% Brand New condition, offering a definitive replacement solution for maintaining legacy systems without upgrading entire control architectures.

Engineering Advantages

The 2711-K5A1 addresses the specific rigors of the factory floor through its specialized design and communication capabilities:

• Tactile Feedback for Heavy Industry: The mechanical keypad allows operators to input commands accurately while wearing protective gloves. Unlike touchscreens, these tactile buttons provide physical confirmation of every press, reducing input errors in high-vibration or high-cadence environments.

• Deterministic Remote I/O Networking: The integrated RIO port facilitates deterministic communication with Allen-Bradley PLC-5 and SLC 500 controllers. This ensures time-critical data reaches the HMI without the latency issues common in standard serial links.

• Universal Power Flexibility: The internal power supply accepts a wide range of 100-240V AC. This eliminates the need for external voltage step-down transformers and protects the internal electronics against common line voltage fluctuations.

• Legacy System Preservation: As a Brand New unit, the 2711-K5A1 provides a "drop-in" replacement for failed hardware. It utilizes existing panel cutouts and PanelBuilder32 software configurations, enabling immediate restoration of production lines without the downtime associated with modern HMI migrations.

FAQs

• Does the 2711-K5A1 support RS-232 communication with the PLC?

  No. The RS-232 port on this specific model serves as a printer/download port only. You must use the primary Remote I/O (RIO) port to communicate with your PLC-5, SLC, or ControlLogix system.

• Can I replace the backlight if the screen grows dim?

  Yes. This model utilizes a field-replaceable backlight lamp. Installing a new lamp restores original brightness, though starting with our Brand New units ensures you receive a factory-fresh display with zero initial runtime hours.

• Is this unit compatible with PanelBuilder32 software?

  Yes. You program and configure the 2711-K5A1 using Standard PanelBuilder32 software. This allows you to upload existing .PBA or .PVP files directly to the terminal for rapid deployment.

• Does this HMI arrive with mounting hardware?

  We provide the 2711-K5A1 with the necessary mounting clips and a sealing gasket. These components ensure a NEMA-rated seal against your enclosure, protecting the electronics from moisture and dust ingress.
