Description
Product Name: 2711-K14C3 Allen Braley Processor module
Product details:
The Allen-Bradley 2711-K14C3 is a high-performance operator interface terminal from the PanelView 1400 series. Although this specific series has been largely succeeded by the PanelView Plus line, it remains a critical component in many legacy industrial automation systems due to its durability and large display.
1. Product Description
The 2711-K14C3 is a high-end Human-Machine Interface (HMI) that allows operators to monitor and control complex industrial processes. It features a large 14-inch Color CRT display, which was a gold standard for visibility in its era.
This model is a Keypad-only unit, meaning all user inputs are handled through a rugged membrane keypad rather than a touchscreen. It uses DH-485 communication protocols to interface with controllers like the SLC 500 or MicroLogix.
2. Technical Specifications
| Feature | Specification |
| Display Type | 14-inch Color CRT |
| Input Type | Stainless-steel Membrane Keypad (F1–F21 Function Keys) |
| Communication Port | DH-485 |
| Programming Port | RS-232 (Printer/File Transfer) |
| Input Voltage | 85–264V AC (Universal AC) |
| Internal Memory | 1008 KB Non-volatile (Flash) |
| Resolution | 800 x 600 pixels |
| Enclosure Rating | NEMA 4X (Indoor use), IP65 |
3. Key Advantages
-
Large Visual Workspace: The 14-inch screen provides ample space for complex mimic diagrams, alarms, and multi-variable data tracking.
-
Tactile Reliability: The mechanical keypad is ideal for environments where operators wear heavy gloves or where screen splashes might cause false triggers on a touchscreen.
-
Rugged Construction: Built to withstand harsh industrial environments, including high vibration and electromagnetic interference.
-
Legacy Integration: Seamlessly connects to existing DH-485 networks, making it a “drop-in” replacement for maintaining older systems without rewriting entire control programs.
4. Important Considerations & Precautions
-
End-of-Life Status: This series is categorized as “Discontinued” or “Legacy” by Rockwell Automation. Finding new units is difficult; most available units are refurbished or surplus.
-
Heat Dissipation: CRT monitors generate more heat than modern LED/LCD screens. Ensure the control cabinet has adequate ventilation to prevent overheating.
-
Weight: This unit is significantly heavier than modern HMI terminals. Ensure the cabinet door or mounting panel is reinforced to support the weight.
-
Burn-in: Like all CRT displays, it is susceptible to “screen burn” if static images are left on for extended periods. Use screen savers or power-down modes when not in use.
5. Typical Applications
The 2711-K14C3 is commonly used in heavy industrial sectors, including:
-
Oil and Gas: Monitoring pump stations and pressure levels.
-
Automotive: Managing large-scale assembly line status and error reporting.
-
Water Treatment: Visualizing complex flow charts and chemical dosing systems.
-
Food & Beverage: Controlling large-scale mixing and thermal processing units.
