Description
Product Name : 2711-T9A3 Allen‑Bradley Programmable controller
Product details:
The Allen-Bradley 2711-T9A3 is part of the legacy PanelView 900 series. While these units are widely considered “Mature” or “Discontinued” by Rockwell Automation, they remain workhorses in many existing industrial environments due to their rugged build and reliable performance.
1. Product Description
The 2711-T9A3 is an operator interface terminal that allows users to monitor and control applications. It features a monochrome (amber) gas plasma display, which was highly regarded for its high contrast and visibility in various lighting conditions. This specific model uses a touchscreen for user input rather than a keypad.
2. Technical Specifications
Below are the core technical parameters for the 2711-T9A3:
| Parameter | Specification |
| Series | PanelView 900 |
| Input Type | Touchscreen (Analog Resistive) |
| Display Type | AC Gas Plasma (Monochrome Amber) |
| Display Size | 9-inch (Diagonal) |
| Communication Port | DH-485 Port |
| Programming Port | RS-232 (for file transfers/printing) |
| Input Voltage | 85–264V AC (50/60 Hz) |
| Internal Memory | 1008 KB Non-volatile (Application Flash) |
| Software | PanelBuilder32 |
3. Product Advantages
- High Visibility: The gas plasma display offers excellent brightness and a wide viewing angle compared to early LCD technology.
- Rugged Design: Built for harsh industrial environments, featuring a NEMA 4X (IP65) rated front bezel when properly mounted.
- Intuitive Interface: The touchscreen allows for complex screen navigation and direct interaction with “soft” buttons, reducing the need for external physical switches.
- Reliable Communication: The DH-485 protocol is a staple in legacy SLC 500 and MicroLogix systems, ensuring stable data exchange.
4. Considerations & Precautions
Important Note: This product is officially discontinued. Support and spare parts are primarily available through the surplus or refurbished market.
- Burn-in Risk: Like many plasma displays, static images left on the screen for extended periods can cause “burn-in.” Using the built-in screen saver is highly recommended.
- Legacy Software: This unit requires PanelBuilder32 software. Modern Studio 5000 or FactoryTalk View software suites do not natively support editing these legacy files without conversion.
- Battery Maintenance: The internal battery (for time-stamping and real-time clock) has a finite life. If the unit has been in storage, the battery may need replacement.
- Mounting: Ensure the sealing gasket is intact during installation to maintain the environmental rating and prevent moisture ingress.
5. Typical Applications
The 2711-T9A3 is commonly found in older automated systems that require a mid-sized, durable interface. Typical industries include:
- Food and Beverage: Monitoring pasteurization or packaging lines.
- Material Handling: Controlling conveyor systems and sorting logic.
- Water Treatment: Displaying pump status, flow rates, and tank levels.
- Manufacturing: Interfacing with SLC 5/03 or 5/04 controllers for machine-level diagnostics and operation.
