Allen-Bradley 2711-T9C8 PanelView 900 Color Touch Operator Terminal

Product Overview

The Allen-Bradley 2711-T9C8 serves as a robust Human-Machine Interface (HMI) within the PanelView 900 Standard platform. This terminal features a high-visibility 9-inch Active Matrix TFT color display, providing crisp 640 x 480 resolution for complex process visualization. We supply this unit as 100% Brand New and Original, offering a critical hardware solution for facilities maintaining legacy systems that rely on Data Highway Plus (DH+) networking and universal AC power input.

Technical Specifications

Engineering Advantages

• Optimized DH+ Connectivity: The 2711-T9C8 features an integrated Data Highway Plus (DH+) port. This allows the terminal to sit directly on a DH+ blue hose network, facilitating high-speed communication with SLC 500 and PLC-5 controllers without additional gateways.

• Vivid TFT Color Visualization: The Active Matrix TFT display provides superior contrast and viewing angles compared to standard passive displays. This ensures operators can distinguish critical alarm colors and complex process trends even in high-glare industrial environments.

• Universal AC Power Supply: The internal power supply accepts a wide range of 85V to 264V AC. This flexibility eliminates the need for dedicated step-down transformers, allowing direct connection to standard facility power grids worldwide.

• High-Density Touch Interface: The resistive touchscreen utilizes 384 distinct touch cells (24x16 matrix). This high density ensures immediate and accurate command registration, minimizing input errors during time-sensitive manual overrides or setpoint adjustments.

• Robust Hardware Architecture: Built for the plant floor, the 120/240V AC architecture handles industrial electrical noise and voltage fluctuations with ease. The unit manages heat dissipation effectively via its 39W thermal design, maintaining internal component integrity during continuous 24/7 operation.

FAQs

• What is the significance of the "Series E" memory upgrade?

  Units from Series E onwards provide 1008 KB of nonvolatile application memory, nearly four times the capacity of earlier versions. This allows for more complex screen hierarchies, larger bitmaps, and extensive alarm history storage without compromising performance.

• Does the RS-232 port support PLC communication?

  No. The RS-232 port on the 2711-T9C8 functions specifically as a printer port for generating hard-copy reports or alarm logs. Use the DH+ port exclusively for communication with your controller network.

• How do I maintain the 9-inch display backlight?

  The integrated CCF backlight offers a long operational life. However, if the screen dims, you can replace the backlight assembly to restore original brightness. We recommend performing this in a clean environment to prevent dust ingress into the TFT layers.

• Can I replace a 2711-T9C1 with this 2711-T9C8?

  While the display and physical dimensions are identical, the 2711-T9C1 uses Remote I/O (RIO) communications, whereas the 2711-T9C8 uses Data Highway Plus (DH+). You must verify your network protocol before upgrading to ensure the ports match your existing cable infrastructure.
