Allen-Bradley 2711-T9A8L1 PanelView 900 Human Machine Interfaces
Configured for graphical operator control and machine visualization across Allen-Bradley controller networks, the Allen-Bradley 2711-T9A8L1 (2711-T9A8L1 Operator Interface) provides direct physical/electrical execution. It handles real-time process monitoring and data input via a 9-inch monochrome touchscreen display using Data Highway Plus (DH+) communication protocols powered by a 24 VDC input supply.
Suffix Breakdown & Model Matrix
- 2711: PanelView Standard Operator Terminal product family platform.
- T9: 9-inch display terminal featuring an analog touchscreen input interface.
- A8: Data Highway Plus (DH+) and RS-232 printer communication interface configuration.
- L1: 24 VDC supply voltage input execution.

Profinet and EtherNet/IP Deterministic Network Integration
The terminal exchanges operational tags and runtime graphic files across industrial control networks via point-to-point or multi-node Data Highway Plus (DH+) links. Its firmware flash compatibility within the 1008K bytes memory space maintains screen application objects and rapid execution states, ensuring low communication latency across local controller backplane connections and network modules.
Frequently Asked Questions
Q: What power precautions must be taken when connecting the 24 VDC input source?
A: Technicians must verify correct polarity on the DC input terminal block before applying power, and tie the chassis ground stud securely to the cabinet ground bar to prevent electrical noise interference.
Q: How does the internal 1008K bytes memory manage application objects and runtime data?
A: The nonvolatile memory stores compiled screen configurations, font files, and runtime graphic objects, executing state updates locally while polling connected controllers via DH+ communication loops.
Field Installation Guidelines
- Cut the panel mounting opening accurately according to PanelView 900 dimensions, ensuring the gasket forms a continuous seal against the enclosure face.
- Torque all bezel mounting clips uniformly around the perimeter to maintain panel ingress protection ratings and prevent mechanical stress on the monochrome screen.
- Terminate Data Highway Plus cables using shielded twinaxial media, grounding the shield drain wire at a single earth reference point to minimize serial noise interference.
