Model 2711-t9a1_a_panelview_900

Product Overview

The 2711-T9A1 is a PanelView 900 Standard Operator Terminal from Allen-Bradley, designed as a monochrome human-machine interface for industrial control applications. As a member of the PanelView Standard terminal family, the 2711-T9A1 provides operators with a centralized platform for monitoring and controlling machinery and processes on the factory floor, eliminating the need to access individual instruments locally .

The 2711-T9A1 features a 9-inch monochrome display with analog resistive touchscreen input, offering 640 x 400 pixel resolution and support for four shades of gray graphics. The terminal is powered by an external 85–264 VAC supply and includes a Remote I/O (RIO) communication port for connection to Allen-Bradley programmable controllers, along with an RS-232 port for printer connectivity . Application programs are developed using PanelBuilder32 software, with memory capacities of 240 KB for units prior to Series E and 1008 KB for Series E and later revisions .

The 2711-T9A1 has been discontinued by Rockwell Automation and is classified as an obsolete product . It therefore serves as a sustainment solution for existing PanelView 900 installations, where a failed terminal must be replaced with a compatible unit to preserve validated HMI applications and avoid the engineering effort associated with migrating to a modern platform.

Main Features and Advantages

Centralized operator control: The 2711-T9A1 consolidates machine and process data into a single display, providing operators with real-time visualization of system status without requiring local access to individual instruments . This centralized approach improves operational accuracy and response time on the factory floor.

Remote I/O connectivity for legacy systems: The 2711-T9A1 includes a built-in Remote I/O (RIO) port supporting communication with Allen-Bradley PLCs and SLC controllers over long distances using standard 1770-CD (Belden 9463) three-wire cable . This legacy protocol support allows the terminal to integrate seamlessly into existing control architectures without protocol conversion gateways.

PanelBuilder32 software environment: The 2711-T9A1 is programmed using PanelBuilder32, Allen-Bradley’s established HMI development environment for the PanelView Standard platform. Applications support universal language switching, analog gauges, screen security, and alarm handling . The RS-232 printer port enables online printing of alarm and event logs for documentation and historical records .

Durable industrial construction: The 2711-T9A1 is designed for flush mounting in enclosures rated NEMA Type 12/13, 4X (indoor), IP54, and IP65, protecting the terminal from dust, splashing water, and other environmental contaminants typical of industrial settings . The 100,000-hour backlight life minimizes maintenance requirements over the terminal’s operational lifespan.
