2711-T9A2 | Allen Bradley | PanelView 900 Standard Monochrome Touch Terminal

Product Overview

The Allen Bradley 2711-T9A2 serves as a specialized Human-Machine Interface (HMI) within the PanelView 900 Standard series. This terminal utilizes a 9-inch monochrome AC Gas Plasma display, providing high-contrast visualization for industrial environments where standard LCDs may struggle with viewing angles. It interfaces directly with SLC 500 or MicroLogix controllers via the DH-485 protocol, enabling real-time process monitoring and touch-sensitive operator input. We supply this unit in 100% Brand New, factory-original condition, ensuring maximum service life for your legacy automation systems.

Technical Specifications

Engineering Advantages

• Superior Visual Clarity: The AC Gas Plasma display offers a wider viewing angle and sharper contrast compared to traditional monochrome LCDs. This technology ensures that operators can read critical machine data clearly from various positions on the plant floor.

• Rugged Touch Interface: The 384-cell touch grid provides responsive tactile input. Each 26 x 25 pixel touch cell allows for generous button sizing, reducing operator input errors even when wearing industrial gloves.

• Flexible Power Integration: The wide input voltage range (85–264V AC) accommodates global power standards. This internal power supply filters line noise and handles frequency fluctuations, protecting the internal electronics from unstable industrial grids.

• Extended Legacy Support: The 2711-T9A2 maintains full compatibility with PanelBuilder32 software. This allows for immediate drop-in replacement of existing units without the need for time-consuming screen redesigns or tag database migrations.

• Robust Thermal Management: The chassis dissipates 39 Watts of heat efficiently. This design prevents internal component degradation in high-ambient temperature cabinets, maintaining performance up to 55 °C.

FAQs

• Can the 2711-T9A2 replace a 2711-T9A1 model?

  The 2711-T9A2 uses the DH-485 communication protocol. If your existing 2711-T9A1 utilizes the same DH-485 network, this unit serves as a direct functional replacement. Always verify the communication port type and existing cabling (such as the 1747-UIC) before installation.

• How does the memory capacity differ between series versions?

  Units manufactured prior to Series E contain 240K bytes of application memory. Our current stock features the later Series (E and F) versions, which provide 1008K bytes. This expanded memory accommodates larger graphics libraries and more complex alarm databases.

• Is this a refurbished unit since the manufacturer discontinued the line?

  No. Despite the "Discontinued" status from the OEM, we provide this specific 2711-T9A2 as 100% Brand New. It remains in its original factory packaging with zero hours of operation, ensuring you receive a product free from the "burn-in" issues common in used gas plasma displays.

• What is the best way to clean the touchscreen surface?

  Use a clean, lint-free cloth dampened with a mild, non-abrasive soap or a specialized industrial screen cleaner. Avoid applying high-pressure water or harsh chemical solvents, which can damage the touch cells or the gas plasma display seal.
