Product Details

Module Overview

The 2711-T5A16L1 is a legacy high-performance Human Machine Interface (HMI) from the Allen-Bradley PanelView 550 Standard series. Featuring a 5.5-inch monochrome blue-mode LCD, this terminal is designed for localized machine control where simple, reliable operator input is required. It utilizes a resistive touchscreen interface, allowing operators to interact directly with on-screen graphics to trigger PLC logic. Equipped with an RS-232 (DF1) port, the 2711-T5A16L1 provides a direct point-to-point connection to MicroLogix, SLC 500, and ControlLogix controllers, making it a staple in vintage automation systems and long-term maintenance applications.

Detailed Engineering Specifications

The 2711-T5A16L1 is a DC-powered unit engineered for longevity, boasting a 100,000-hour backlight life.

  • Display Type: Monochrome LCD (Blue Mode)

  • Display Size: 5.5 inches (120 x 60 mm / 4.75 x 2.38 in.)

  • Resolution: 256 x 128 Pixels

  • Input Type: Analog Resistive Touchscreen

  • Touch Cells: 128 (16 Columns x 8 Rows)

  • Touch Cell Size: 26 x 30 Pixels

  • Backlight: Integrated LED (100,000-hour service life)

  • Application Memory: 170 KB Runtime / 240 KB Non-volatile RAM

  • Communication Ports: * RS-232 (DF1) for Controller Communication

    • RS-232 for Printer/Application Download

  • Input Power: 24V DC (Range: 18–30V DC)

  • Heat Dissipation: 20 Watts (69 BTU/HR)

  • Operating Temperature: 0°C to 55°C (32°F to 131°F)

  • Enclosure Rating: NEMA Type 12/13, 4X (Indoor use only)

  • Physical Weight: 2.00 lbs (0.91 kg)

Communication and Software Integration

This terminal uses the DF1 protocol for communication, a robust serial standard for Rockwell Automation hardware. For successful integration, the 2711-NC13 communication cable is typically required to link the HMI to the processor's serial port. Configuration and screen design are managed via PanelBuilder32 software. While this software is legacy, it allows for the creation of intricate tag-based screens, alarm management, and real-time data trending.

Installation and Mechanical Reliability

The 2711-T5A16L1 is built for industrial durability. Its front panel is rated for NEMA 4X environments, meaning it can withstand "wash-down" conditions when properly installed in a sealed enclosure. The unit is secured using functional mounting clips that compress a high-quality gasket against the panel cutout, ensuring an airtight and dust-tight seal.

Technical FAQ

Can I upgrade the memory on the 2711-T5A16L1?

No. The internal application memory is fixed. However, you can use ATA Flash memory cards to transfer applications or store log data, provided they are formatted for use with the PanelView Standard system.

Is the backlight replaceable?

On the 2711-T5A16L1, the LED backlight is integrated. With a 100,000-hour rating, it is designed to last the entire life of the terminal. If the screen goes dark, it often indicates a failure of the internal power inverter rather than the LED itself.

How do I download a program if I don't have a DF1 port on my PC?

You will need a high-quality USB-to-RS232 converter (such as the 1747-UIC or a similar industrial-grade adapter) to communicate between a modern laptop running PanelBuilder32 and the HMI's RS-232 port.
