2711-NL3 | Allen-Bradley PanelView 600 Replacement Backlight Lamp

Product Overview

The Allen-Bradley 2711-NL3 serves as the essential replacement illumination source for legacy PanelView 600 Operator Interface Terminals. This high-intensity Cold-Cathode Fluorescent Lamp (CCFL) restores full visibility to dimmed or flickering HMI screens, ensuring operators can monitor critical process data without visual strain. Specifically engineered for Series A and B hardware, the 2711-NL3 maintains the original factory brightness specifications required for industrial environments. We provide this component in 100% Brand New condition to guarantee maximum service life and immediate restoration of display performance.

Technical Specifications

The 2711-NL3 meets the following technical requirements for industrial display systems:

• Lamp Type: Cold-Cathode Fluorescent Lamp (CCFL)

• Compatibility: PanelView 600 Keypad or Keypad & Touch (Series A and B only)

• Rated Bulb Life: 20,000 Hours

• Weight: 0.24 lbs (approx. 0.11 kg)

• Category: OIT Replacement Hardware

• Function: Internal Display Illumination

Engineering Advantages

The 2711-NL3 solves specific maintenance challenges associated with aging HMI infrastructure:

• Instant Display Restoration: Replacing a degraded lamp with a brand-new 2711-NL3 eliminates "dark screen" failures, preventing unnecessary and costly HMI terminal replacements.

• Extended Operational Lifecycle: The 20,000-hour rated life ensures long-term reliability, reducing the frequency of maintenance cycles and minimizing downtime in 24/7 manufacturing operations.

• Precision Fit for Legacy Chassis: This lamp fits perfectly within the internal housing of PanelView 600 Series A and B units. The design facilitates a direct physical swap, ensuring the light distributes evenly across the 5-inch display without hotspots or shadows.

• High-Contrast Visibility: The CCFL technology produces a sharp, clear light output that cuts through high-ambient factory lighting, maintaining the readability of safety warnings and system parameters.

FAQs

• Will the 2711-NL3 work with a Series C PanelView 600?

  No. The 2711-NL3 specifically supports Series A and B terminals. Series C and later versions often utilize different backlight architectures. Always check the series letter on your terminal’s data plate before installation.

• Can I replace this lamp while the HMI is powered on?

  No. You must disconnect the 18-32V DC power source before opening the terminal. CCFL lamps require high-voltage inverters to operate; performing a replacement on a live unit creates a significant risk of electrical shock and damage to the HMI's internal circuitry.

• Is this a genuine, new bulb or a refurbished unit?

  We sell only 100% Brand New 2711-NL3 lamps. Since fluorescent bulbs degrade with use, a brand-new unit is the only way to ensure the full 20,000-hour lifespan and original factory brightness.

• Do I need to replace the entire HMI if the screen goes black?

  Often, no. If the terminal still communicates with the PLC but the image is not visible, the backlight has likely reached its end-of-life. Installing a new 2711-NL3 usually resolves the issue at a fraction of the cost of a new terminal.
