2711-T5A2L1 | Allen-Bradley | PanelView 550 Standard Touch Terminal

Product Overview

The Allen-Bradley 2711-T5A2L1 functions as a rugged Human-Machine Interface (HMI) within the PanelView 550 Standard series. This terminal streamlines operator interaction through a sensitive 5.5-inch touch interface, eliminating the need for bulky physical buttons. It specializes in DH-485 communication, allowing seamless data exchange with SLC 500 and MicroLogix controllers. While the manufacturer lists this series as discontinued, we offer this unit as 100% Brand New original stock to ensure your legacy systems maintain peak operational availability without the risks of refurbished hardware.

Technical Specifications

The 2711-T5A2L1 utilizes high-efficiency internal components to provide clear visualization and responsive control:

Engineering Advantages

• Optimized for DC Power Environments: The 24V DC input makes this terminal ideal for mobile equipment, remote stations, or control panels where AC power is unavailable or undesired. The wide 18–30V DC range accommodates standard battery-backed system fluctuations.

• Superior Visual Longevity: The 100,000-hour LED backlight outlasts traditional CCFL lamps found in older HMI models. This ensures consistent brightness and readability across decades of continuous operation, reducing maintenance overhead.

• Precision Touch Grid: The touchscreen architecture consists of 128 individual touch cells (each 26 x 30 pixels). This density allows for precise button placement and minimizes accidental triggers, even in high-vibration environments.

• Legacy DH-485 Support: The integrated DH-485 port facilitates direct connection to existing PLC networks via the 1747-C10 cable. This allows for immediate hardware replacement in aging plants without requiring expensive network architecture redesigns or protocol converters.

FAQs

• Q: Can the 2711-T5A2L1 replace an AC-powered PanelView 550?

• A: Only if you have a 24V DC power source available in the cabinet. This specific "L1" model operates exclusively on DC power. Check your existing terminal's part number; if it ends in "L1," this is the direct replacement.

• Q: How do I transfer my existing application to this new terminal?

• A: Use PanelBuilder32 software to download your application file. Since we provide this unit as Brand New, the internal nonvolatile RAM (240 KB) is ready to accept fresh application objects, bitmaps, and text.

• Q: What is the benefit of the Blue Mode Monochrome display?

• A: Blue mode offers superior contrast ratios in industrial lighting conditions compared to standard grayscale. It improves legibility for critical alarms and process values from wider viewing angles.

• Q: Does this unit include mounting hardware?

• A: Yes. We ship the 100% Brand New unit with its original factory-sealed mounting clips and gaskets to ensure a NEMA-rated seal upon installation into your enclosure.
