Key Features & Benefits
-
5.7-inch color display: Provides clear visual feedback for operators, reducing errors and improving response times.
-
Keypad input: Allows quick data entry even in environments where touchscreens are impractical, such as when operators wear gloves.
-
Dual communication ports: Ethernet and RS-232 offer flexible connectivity, enabling integration with PLCs, drives, and other industrial devices.
-
Wide input power range (18-30 VDC): Ensures reliable operation despite voltage fluctuations common in industrial settings.
-
256 MB RAM: Supports smooth application execution and faster screen transitions.
Industry Applications
The Allen-Bradley 2711P-K6C20D9 excels in applications where reliable operator interaction is critical. Typical use cases include:
-
Machine control panels: Operators use the keypad to set parameters, start or stop cycles, and monitor production status on the color display.
-
Process monitoring: In continuous processes such as packaging or material handling, the 2711P-K6C20D9 presents real-time data and alarms, allowing quick corrective actions.
-
Material handling systems: The Ethernet port connects to a controller on an EtherNet/IP network, enabling real-time I/O messaging and message exchange, which helps coordinate conveyors and sorters.
Because the 2711P-K6C20D9 supports both Ethernet and RS-232, it adapts well to both legacy and modern control architectures.
Installation & Setup Guidance
When installing the Allen-Bradley 2711P-K6C20D9, follow these practical steps:
-
Power supply: Connect a DC power source within the 18-30 VDC range. Use appropriately sized wiring to minimize voltage drop.
-
Communication wiring: For Ethernet, use a standard RJ45 cable with a 10/100Base-T connector. The port supports MDI/MDI-X, so crossover cables are not required. For RS-232, use the designated serial cable (e.g., 2711-NC13) and verify pinout.
-
Mounting: Panel-mount the terminal in a location that provides easy operator access while protecting the unit from excessive vibration, moisture, and extreme temperatures.
-
Configuration: Download the application parameters via the Ethernet port. The EtherNet/IP screen on the terminal allows you to modify communication settings as needed.
Proper setup ensures the 2711P-K6C20D9 performs reliably from day one.
Maintenance & Reliability
Routine maintenance for the 2711P-K6C20D9 focuses on keeping the unit clean and ensuring stable power. Inspect the display and keypad periodically for dust or debris that could obscure visibility or impair input. Check all cable connections for tightness and signs of wear. Because the backlight is non-replaceable, handle the unit carefully to avoid damaging the display.
The 2711P-K6C20D9’s robust design and wide input voltage tolerance reduce the risk of unexpected downtime, making it a cost-effective choice for long-term operation.
Compatibility & Integration
The Allen-Bradley 2711P-K6C20D9 integrates seamlessly with Rockwell Automation control systems. Its Ethernet port connects to controllers on an EtherNet/IP network, supporting real-time I/O messaging and standard Ethernet communications. The RS-232 port provides a secondary channel for connecting to legacy devices or for local programming.
For applications requiring an additional Ethernet port, the 2711P-RN20 Ethernet communication module is available for use with larger terminals (700 to 1500 series). The 2711P-K6C20D9 itself includes a single Ethernet port with an RJ45 connector.
Buying Guide
Before purchasing the Allen-Bradley 2711P-K6C20D9, verify that your application’s requirements match its capabilities. Confirm the input power range (18-30 VDC) is compatible with your facility’s supply. Ensure the display size and keypad input suit your operators’ needs. Check that the communication ports (Ethernet and RS-232) align with your network infrastructure.
