Product Overview

The Allen Bradley 2711-K5A20 serves as a specialized Human-Machine Interface (HMI) designed for high-performance machine-level visualization within the PanelView 550 Standard series. This terminal features a rugged tactile keypad and integrated Ethernet communication, providing a direct digital link to SLC 500, MicroLogix, and ControlLogix controllers. We supply this unit as 100% Brand New and Factory Original, offering a critical solution for facilities that must maintain validated legacy control systems without the high cost of a full panel redesign.

Technical Specifications

The 2711-K5A20 utilizes industrial-grade hardware to ensure data persistence and display clarity in factory environments:

Engineering Advantages

• Native Ethernet Connectivity: This terminal incorporates a built-in Ethernet port, enabling high-speed data transfer and seamless integration into plant-wide networks. It eliminates the need for external protocol converters and allows for remote diagnostics and centralized data collection.

• Tactile Keypad Precision: The physical keypad provides definitive mechanical feedback, which ensures accurate command entry even when operators wear heavy protective gloves. This mechanical design prevents the accidental triggering often associated with touchscreens in high-vibration or electrically noisy environments.

• Universal AC Power Input: The internal power supply accepts a wide range of 100–240V AC. This versatility allows for global installation without requiring localized voltage transformers, simplifying spare parts inventory for international manufacturers.

• High-Contrast Blue Mode Display: The blue monochrome LCD delivers excellent visibility under varied lighting conditions. It maintains sharp text and icon clarity, ensuring operators can read critical alarms and process variables from multiple viewing angles.

• Legacy Architecture Support: As a brand-new original unit, the 2711-K5A20 replaces failed obsolete hardware instantly. It allows maintenance teams to restore machine operation by simply moving the existing memory card or downloading the original PanelBuilder32 file.

FAQs

• Is this 2711-K5A20 unit 100% Brand New?

  Yes. We guarantee this unit is 100% Brand New and ships in its original factory-sealed Allen Bradley packaging. We do not supply refurbished or used surplus, ensuring your facility receives hardware with its full original backlight and component lifespan.

• Can I use the RS-232 port for controller communication?

  The RS-232 port on the 2711-K5A20 functions primarily as a printer port for alarm logs or as a download port. Primary controller communication occurs through the Ethernet port. If you require DH-485 or DH+ communication, you must select the appropriate 2711-K5A5 or 2711-K5A8 models.

• What software do I need to program this terminal?

  You must use PanelBuilder32 software. The terminal supports application downloads directly over the Ethernet network or through a point-to-point RS-232 connection using a 2711-NC13 cable.

• Does the unit come with mounting hardware?

  Yes. The factory-original unit includes the necessary mounting clips and the environmental sealing gasket to maintain the integrity of your enclosure's NEMA rating.
