The Allen-Bradley 2706-P22R, also cataloged as the 2706P22R In-View Message Display, operates as a dedicated hardware component for localized alphanumeric status messaging and alarm annunciation within industrial control network platforms.

Model Matrix

• 2706-P22R: Standard panel mount catalog number.

• P22R: Designator indicating 2-line, 20-character red LED display configuration.

Hardware Specifications

Industrial Control System Integration

The display unit supports deterministic data receipt via serial communication interfaces. It enables I/O density scaling by providing direct visual feedback from PLC registers without occupying additional control-cabinet I/O slots. Firmware flash compatibility is maintained through serial updates to ensure alignment with existing communication protocols and network timing constraints, facilitating seamless integration into EtherNet/IP or legacy serial control architectures.

Ordering Information

• 2706-P22R In-View Message Display module.

• Integrated mounting hardware for panel installation.

• Note: Communication cables and programming software are not included with the standard hardware delivery.

Field Installation Guidelines

• Panel Mounting: Ensure the cutout dimensions conform to the specifications to maintain the NEMA 4/4X seal integrity. Utilize the provided mounting hardware to distribute clamping force evenly.

• Shielding: Use shielded twisted-pair cabling for serial communication to minimize signal interference. Ground the cable shield at the control cabinet entry point only to prevent ground loops.

• Wiring: Maintain physical separation between high-voltage power lines and low-voltage communication signals to prevent electromagnetic induction.

• Cleaning: Clean the display front with non-abrasive, industrial-grade cleaning agents compatible with NEMA 4/4X rated materials.

Frequently Asked Questions

• Does the display support hot-swapping? No, the unit must be disconnected from all power and communication sources before removal to prevent potential short-circuiting of the backplane interface.

• Is the LED brightness adjustable? Yes, intensity is configurable via the internal software menu to accommodate ambient lighting conditions.

• Can this display be used in hazardous locations? The NEMA 4/4X rating defines ingress protection; consult the certification label on the unit for specific Class/Division hazardous location ratings.

• What serial protocols are supported? The unit supports standard point-to-point and multi-drop serial protocols for data ingestion.

• How is the display updated? Data updates are transmitted from the PLC host; ensure the communication baud rate matches the host controller settings exactly.

• Does it require an external power supply? Yes, it requires a dedicated power connection; verify input voltage ranges against the rating plate on the unit chassis.

• Is the display panel replaceable? The display module is integrated; failure of the LED array requires replacement of the entire 2706-P22R assembly.

• Are terminal blocks included? Terminal blocks for power and communications are integrated; ensure wire gauge is appropriate for the screw-clamp connectors.
