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.
