Allen-Bradley 2711P-RL7C PanelView Plus Backlight Module

The Allen-Bradley 2711P-RL7C, also cataloged as the 2711P-RL7C Color Backlight Assembly, operates as a dedicated hardware component for display illumination and luminance execution within PanelView Plus and PanelView Plus CE 700 Series A and B Display platforms.

Hardware Specifications

Deterministic Network Integration and Bus Performance

Configured for precise visual feedback across EtherNet/IP deterministic networks, the Allen-Bradley 2711P-RL7C provides direct illumination for the 700 Series display panel. Stable light output prevents screen dimming and maintain display readability during continuous high-density I/O monitoring. The backlight element integrates directly with internal inverter drive circuitry, maintaining firmware flash compatibility and display response without drawing excessive control power from the terminal backplane.

Frequently Asked Questions

Q: Is live replacement of the 2711P-RL7C backlight assembly permitted while the PanelView terminal is running?

A: Live replacement is strictly prohibited due to high operating voltage generated by the internal backlight inverter. Main control power to the HMI display terminal must be fully isolated before opening the housing.

Q: Which terminal display revisions are compatible with the 2711P-RL7C backlight?

A: The 2711P-RL7C is engineered specifically for Allen-Bradley PanelView Plus 700 and PanelView Plus CE 700 Series A and Series B display units.

Field Installation Guidelines

1. Disconnect all AC or DC main power feeds connected to the PanelView terminal and wait at least 5 minutes for internal capacitors to discharge.
2. Remove the terminal display module from the enclosure panel using standard hand tools while observing ESD grounding protocols.
3. Access the rear display casing and carefully detach the backlight retention clip and high-voltage inverter connector.
4. Insert the new 2711P-RL7C backlight assembly into the housing channel, ensuring electrical contacts align without mechanical binding.
5. Reassemble the display housing, re-mount the terminal into the panel cutout, and restore system power to test backlight operation.
