2711-T5A16L1 | Allen Bradley | PanelView 550 Standard Operator Terminal

The Allen Bradley 2711-T5A16L1, also cataloged as the 2711-T5A16L1 Operator Terminal, operates as a dedicated hardware component for human-machine interface visualization and process monitoring within industrial control platforms.

Suffix Breakdown & Model Matrix

The 2711-T5A16L1 belongs to the PanelView 550 standard terminal product line. The "T" designator identifies the touchscreen input interface, while the "5" denotes the 5.5 inch monochrome display size. The "A" suffix specifies the primary communication port type, and the "16L1" configuration identifies the specific firmware and internal memory allocation of 170 KB for application runtime. This unit maintains backward compatibility across Series A through H hardware revisions.

Hardware Specifications

Industrial Control & Firmware Compatibility

The 2711-T5A16L1 requires strict adherence to firmware flash compatibility standards to ensure stability during the execution of runtime applications. The terminal manages data exchange via RS-232 DF1 protocols, where deterministic communication relies on the integrity of the serial baud rate settings. Backplane bus communication velocity is not applicable to this standalone terminal, but users must ensure that memory allocation for bitmaps and text objects does not exceed the 240 KB nonvolatile RAM capacity. I/O density scaling within the terminal is limited by the predefined touchscreen matrix of 16 columns by 8 rows.

Frequently Asked Questions

Q: Is the LED backlight field-replaceable?

A: No. The LED backlight is integrated into the display assembly and is rated for a 100,000 hour service life. If the backlight fails, the complete display assembly or terminal must be addressed.

Q: Can this terminal interface with modern Ethernet-based PLC systems?

A: No. This terminal is limited to serial RS-232 (DF1) communication. Interfacing with modern networks requires an external protocol converter or gateway to translate serial signals to the required industrial network standard.

Field Installation Guidelines

1. Panel Cutout: Ensure the panel cutout dimensions conform to the specifications provided in the installation manual to maintain the NEMA/IP seal rating.
2. Mounting: Use the provided mounting clips to secure the terminal against the enclosure panel. Tighten clips evenly to ensure a uniform gasket seal.
3. Power Wiring: Connect 24 VDC power to the terminal. Use a dedicated supply and ensure proper grounding to the chassis ground stud to minimize electrical noise.
4. Communication Cable: Utilize the 2711-NC13 serial cable for PLC connections. Ensure all cables are routed away from high-voltage AC lines to prevent signal interference.
5. Touchscreen Calibration: Upon initial power-up, perform the touchscreen calibration routine to align the physical touch cells with the displayed application objects.
