Description
The Allen-Bradley 2711-B5A9L1, also cataloged as the 2711-B5A9L1 PanelView Standard Operator Interface, operates as a dedicated hardware component for process visualization and operator parameter input within DH-485 network architectures. Powered by an internal 24 VDC power power supply, the unit provides direct physical/electrical execution through its 5.3-inch monochrome display (256 x 128 pixels), dual keypad and touch input matrix, and RS-232 communication interfaces for real-time controller interaction and local printer output.

Profinet / EtherNet/IP Deterministic Networks & Firmware Flash Compatibility
The operator interface communicates across industrial network structures, processing high-speed serial bitstream exchanges with host PLC-5, SLC 500, or MicroLogix 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 input power requirements for the 2711-B5A9L1 operator interface?
A: The terminal operates on 24 VDC nominal field power with an allowable operating range of 18 to 32 VDC.
Q: Can both the DH-485 serial port and the printer port be used simultaneously?
A: Yes, the primary RS-232 port handles real-time controller tag exchange using DH-485 protocol, while the secondary RS-232 printer port operates independently for asynchronous alarm and report printing.
Q: What input options are available on the 2711-B5A9L1 PanelView 550 terminal?
A: The module supports dual operator input via physical tactile function keys (F1 through F10) and an analog resistive touch screen area.
Field Installation Guidelines
- Cut the cabinet panel cutout to match standard PanelView 550 mounting dimensions, ensuring the panel face is clean and rigid.
- Fit the terminal into the cutout and tighten the perimeter mounting clips evenly to ensure a NEMA-rated enclosure seal.
- Wire the external 24 VDC power supply to the terminal power block, verifying correct polarity before energizing the unit.
- Route the RS-232 communication cable separately from high-voltage AC lines and variable frequency drive motor leads to prevent data corruption.
- Secure the protective earth (PE) ground lead directly to the terminal chassis grounding stud using a low-impedance copper strap.
