Allen Bradley 2711-T5A15L1 PanelView 550 ControlNet Monochrome Touch Terminal

Product Overview

The Allen Bradley 2711-T5A15L1 functions as a ruggedized operator interface within the PanelView 550 Standard series, specifically engineered for high-speed ControlNet network architectures. This terminal features a 5.5-inch monochrome LCD with a blue mode display, providing high-contrast visualization for industrial machinery status and data entry. It facilitates real-time deterministic communication between the operator and the PLC. We supply this unit as 100% Brand New and Factory Original, offering a critical hardware solution to sustain legacy systems that have reached discontinued status.

Technical Specifications

The 2711-T5A15L1 utilizes industrial-grade hardware to maintain data integrity and display longevity:

Engineering Advantages

• Deterministic Network Integration: The integrated ControlNet port enables scheduled, high-speed data transfers. This ensures the HMI receives mission-critical process variables with precise timing, a requirement for synchronized production lines where standard Ethernet latency remains unacceptable.

• Superior Backlight Longevity: The 100,000-hour LED backlight significantly outperforms standard CCFL lamps found in older HMI models. This extended lifespan reduces maintenance cycles and prevents display dimming in 24/7 manufacturing operations.

• Rugged Environmental Sealing: This terminal carries NEMA 4X and IP65 ratings. The front bezel resists water jets, corrosion, and non-corrosive coolants, making the 2711-T5A15L1 ideal for wash-down environments and food processing applications.

• Optimized Installation Depth: With a base depth of only 64 mm, the module fits into shallow control cabinet doors. Even with a memory card retainer, the terminal maintains a compact profile, solving the challenge of high-density component layout in narrow enclosures.

• Electromagnetic Noise Immunity: The ControlNet interface and shielded internal circuitry suppress electromagnetic interference (EMI). This prevents signal corruption and screen "ghosting" when the HMI operates in close proximity to high-power motor starters and variable frequency drives (VFDs).

FAQs

• Is this 2711-T5A15L1 unit 100% Brand New?

  Yes. We guarantee this terminal is 100% Brand New and arrives in its original factory-sealed Allen Bradley packaging. We do not supply refurbished or used surplus, as touchscreen sensitivity and backlight health are critical for the reliability of legacy control systems.

• Does this model require a specific communication cable?

  Yes. For printer port connections, use the 2711-NC13 cable. For the primary ControlNet network link, use standard RG-6 coaxial cable and BNC connectors compliant with Allen Bradley ControlNet installation standards.

• Can I transfer my existing PanelView 550 project to this unit?

  Yes. You can download existing .PVA or .PVP files created in PanelBuilder32 software directly to this terminal. The 240 KB non-volatile memory ensures the application remains stored even during a total loss of DC input power.

• How do I replace the internal clock battery?

  The unit utilizes the 2711-NB4 time clock battery. While we supply the unit brand new, we recommend verifying the battery status during commissioning if the unit has remained in long-term storage, as the real-time clock depends on this power source for timestamped alarm logging.
