Display and Performance
The 2711P-K6C3A features a 5.7-inch color active matrix display with an 111mm x 84mm display area and 320 x 240-pixel resolution (18-bit color graphics). Display brightness is 300 cd/m², with a non-replaceable CCFL backlight rated for 50,000 hours. The battery-backed real-time clock maintains accuracy within ±2 minutes per month.
Memory and Processing
Equipped with an NEC VR5532A MIPS CPU (350MHz), the 2711P-K6C3A offers 64MB non-volatile user memory and 64MB PC100 SDRAM SODIMM volatile memory. This configuration supports efficient data handling and application execution.
Environmental and Physical
Operating temperature range is 0-55°C at 5-95% non-condensing relative humidity. Storage temperature ranges from -25 to 70°C. The unit withstands 15G operational shock and 2G vibration at 57-500Hz. It weighs 930g (2.05lb) with dimensions of 167mm x 266mm x 98mm.
Industry Applications
The Allen-Bradley 2711P-K6C3A excels in applications requiring durable, keypad-based operator interfaces. Common uses include:
-
Packaging machinery: Monitor and control filling, sealing, and labeling lines.
-
Material handling: Interface with conveyors, sorters, and robotic cells.
-
Process control: Display real-time process data and alarms in chemical or food processing plants.
Because the 2711P-K6C3A supports RS-232, USB, Ethernet, and DH-485, it integrates easily into existing control systems, making it a versatile choice for retrofits and upgrades.
Installation & Setup Guidance
When installing the 2711P-K6C3A, follow these guidelines:
- Mount the terminal in a panel with adequate clearance for ventilation and cable routing.
- Connect power to the 85-265V AC input, ensuring proper grounding and using a dedicated circuit.
- For Ethernet communication, use a shielded CAT5 cable and configure the IP address via the terminal's setup menu.
- For RS-232 or DH-485, verify baud rate and station address settings match the host controller.
- Use the USB port for firmware updates or data transfer only when the terminal is powered down to avoid interruptions.
Maintenance & Reliability
Although the 2711P-K6C3A is discontinued, regular maintenance extends its service life:
- Clean the display and keypad with a soft, dry cloth to prevent dust accumulation.
- Check the backlight brightness periodically; dimming may indicate aging.
- Verify the battery-backed clock's accuracy and replace the battery if time drifts beyond ±2 minutes/month.
- Inspect connectors and cables for wear or corrosion annually.
Operating within the specified temperature and humidity ranges reduces stress on internal components and improves reliability.
Compatibility & Integration
The 2711P-K6C3A communicates via RS-232, USB, Ethernet, and DH-485, making it compatible with Rockwell Automation controllers such as MicroLogix, CompactLogix, and ControlLogix platforms. It also works with legacy SLC 500 and PLC-5 systems through DH-485 or Ethernet. For new installations, consider using the PanelView Plus 7 series, but the 2711P-K6C3A remains a cost-effective replacement for existing PanelView Plus 600 applications.
Selection Guide & Purchasing Advice
Before purchasing the Allen-Bradley 2711P-K6C3A, verify the following:
- Confirm the power supply voltage matches your facility (120V AC nominal).
- Check communication requirements: Ethernet, RS-232, or DH-485.
- Ensure the keypad layout suits your operators' needs.
- Review the lifecycle status: as a discontinued product, the 2711P-K6C3A is available as a surplus or refurbished unit.
