Allen-Bradley 2711-B5A8L2 PanelView 550 Operator Interface

Configured for process visualization and operator parameter input within Data Highway Plus (DH+) network architectures, the Allen-Bradley 2711-B5A8L2 (2711-B5A8L2 Operator Terminal) provides direct physical/electrical execution. Powered by a 24 VDC input, the terminal incorporates a 5.5-inch monochrome LCD display (256 x 128 resolution) with dual keypad and touchscreen entry modes for real-time controller interaction and plant-floor monitoring.

Profinet / EtherNet/IP Deterministic Networks & Firmware Flash Compatibility

The operator interface communicates across industrial network structures, processing high-speed serial and DH+ network bitstream exchanges with host PLC-5, SLC 500, or ControlLogix controllers. Onboard logic circuits maintain strict firmware flash compatibility with PanelBuilder32 software suites, assuring deterministic register updates across mapped I/O bits and integer files. High dielectric isolation across the 24 VDC power input terminals shields internal microcontroller logic from ground potential shifts and high-frequency noise transients present on backplane and field network lines.

Frequently Asked Questions

Q: What are the power supply requirements for the 2711-B5A8L2 terminal?

Q: What input options are integrated into the 2711-B5A8L2 terminal?

A: The unit features dual operator entry, utilizing 10 physical tactile function keys (F1 through F10) alongside an analog resistive touchscreen overlay.

Field Installation Guidelines

1. Cut the enclosure panel opening according to standard PanelView 550 mounting dimensions and inspect the environmental sealing gasket.
2. Insert the 2711-B5A8L2 terminal into the panel cutout and tighten all mounting clamps evenly around the perimeter to ensure a NEMA 4X / IP65 seal.
3. Wire the external 24 VDC power supply to the terminal block, verifying correct polarity before energizing the unit.
4. Route the shielded DH+ network cable away from high-voltage AC lines, variable frequency drive output leads, and heavy inductive loads to minimize EMI.
5. Secure a low-impedance protective earth (PE) ground strap directly from the terminal chassis grounding stud to the main cabinet earth bus bar.
