Description
Product Name : 2711-K5A5 Allen‑Bradley Controller module
Product details:
The Allen-Bradley 2711-K5A5 is a member of the PanelView 550 series of Operator Interface Terminals. Although this specific series has been largely superseded by newer lines (like the PanelView Plus), it remains a staple in many legacy industrial automation systems due to its rugged reliability.
Below is a detailed breakdown of the product.
1. Product Description
The 2711-K5A5 is an electronic operator interface that allows users to monitor and control applications managed by an Allen-Bradley PLC (Programmable Logic Controller). It features a monochrome LCD display and a tactile keypad for input, designed specifically for harsh industrial environments where touchscreen interaction might be impractical (e.g., users wearing heavy gloves).
2. Technical Specifications
| Parameter | Specification |
| Display Type | Blue Mode Monochrome Liquid Crystal Display (LCD) |
| Display Size | 5.5-inch |
| Resolution | 256 \times 128 pixels |
| Input Method | Stainless-steel tactile domed Keypad (F1–F10 Function Keys) |
| Communication Port | DH-485 (Data Highway 485) |
| Programming Port | RS-232 (for configuration/uploading) |
| Input Voltage | 120V AC (85–264V AC operating range) |
| Memory | 170 KB Application Runtime Memory |
| Backlight | Replaceable LED (usually rated for 100,000 hours) |
| Enclosure Rating | NEMA 4X (Indoor use), IP65 |
3. Product Advantages
- Industrial Durability: The keypad interface is highly resistant to vibration, shock, and contaminants that might interfere with touchscreen sensitivity.
- Compact Footprint: The 5.5-inch screen offers a balance between visibility and space-saving, making it ideal for small control panels.
- DH-485 Compatibility: Provides direct, reliable communication with SLC 500 and MicroLogix controllers without needing complex gateways.
- Ease of Maintenance: Features a field-replaceable backlight, extending the unit’s lifecycle significantly.
4. Key Applications
The 2711-K5A5 is typically found in “mid-range” automation tasks, including:
- Material Handling: Conveyor belt control and sorting systems.
- Food & Beverage: Simple packaging machines and bottling lines.
- Water Treatment: Monitoring pump stations and valve positions.
- Legacy System Maintenance: Serving as a drop-in replacement for failed units in older factories still running on DH-485 networks.
5. Important Considerations & Precautions
- End-of-Life Status: The PanelView 550 series is largely discontinued by Rockwell Automation. While units are available as “refurbished” or “surplus,” new installations should consider the PanelView Plus 7 or Panelview 800 for better long-term support.
- Voltage Safety: Ensure the power source matches the AC requirements. Connecting DC power to this specific model will damage the internal power supply.
- Programming Software: This unit requires PanelBuilder32 software for configuration. Modern software like FactoryTalk View Studio does not natively support the older 2711-K5A5 firmware without conversion.
- Mounting: Always use the provided sealing gasket during installation to maintain the NEMA 4X/IP65 rating and prevent moisture from entering the enclosure.
