Description
Configured for process visualization and operator input within Data Highway Plus (DH+) network architectures, the Allen-Bradley 2711-B5A8L3 (2711-B5A8L3 Operator Terminal) provides direct physical/electrical execution. Powered by a 24 VDC input, the terminal incorporates a 5.5-inch monochrome blue-mode LCD (256 x 128 pixels), dual keypad and touchscreen entry interfaces, and a dedicated DH+ communication port alongside an RS-232 serial printer port for real-time plant-floor networking and local data logging.

Profinet / EtherNet/IP Deterministic Networks & Firmware Flash Compatibility
The terminal interfaces directly with Allen-Bradley PLC-5, SLC 500, and ControlLogix systems using Data Highway Plus (DH+) deterministic networks. Embedded firmware flash compatibility maintains seamless register translation and runtime execution across PanelBuilder32 software application files. Internal dielectric power isolation shields display processing logic and communication transceivers from common-mode noise transients and ground potential shifts across field-side cabling.
Frequently Asked Questions
Q: What are the primary communication interfaces integrated into the 2711-B5A8L3 terminal?
A: The terminal features a dedicated Data Highway Plus (DH+) port for high-speed deterministic controller communication and an auxiliary RS-232 serial port dedicated to printer logging and report generation.
Q: What is the operating voltage range for the 2711-B5A8L3 unit?
A: The module requires an external 24 VDC nominal supply with an allowable operating range of 18 to 32 VDC.
Q: How is operator interaction configured on the PanelView 550 2711-B5A8L3 display?
A: The unit features a hybrid operator input system combining 10 physical tactile function keys (F1 through F10) with a 128-cell resistive touch matrix overlay.
Field Installation Guidelines
- Prepare the panel enclosure cutout strictly according to PanelView 550 cutout dimensions to ensure an environmental NEMA/IP seal.
- Insert the terminal into the panel cutout and tighten all mounting clamps evenly around the perimeter.
- Verify that the DC power supply voltage measures within 18 to 32 VDC before terminating connections to the power terminal block.
- Route shielded DH+ and RS-232 communication cables separately from AC power wiring and high-frequency drive output leads to mitigate EMI.
- De-energize primary system power prior to connecting or disconnecting communication lines or performing routine maintenance.
