Technical Specifications

Key Features & Benefits

• Dual Input Options: The Allen-Bradley 2711P-B6M1A includes a stainless-steel domed keypad with function keys and an analog resistive touchscreen, providing flexibility for different operator preferences.
• Robust Construction: Keypad rated for 1,000,000 presses and 340G shock resistance ensures long-term durability in harsh industrial settings.
• Clear Visual Feedback: A 5.5-inch grayscale passive matrix display with 320 x 240 resolution and 32-level grayscale delivers crisp status updates. The antiglare surface improves readability under bright lighting.
• Reliable Memory: 64MB internal user memory stores data and bitmaps. Compatible with 2711P-RC3 and 2711P-RC4 256MB external compact flash cards for expanded storage.
• Flexible Connectivity: Base-configured RS-232, Ethernet, and Remote I/O communication interfaces allow integration into various control architectures.
• Wide Power Range: Accepts 85-256V AC at 47-63Hz, with 60VA maximum power consumption. An external power supply (85-256V AC, 120VA max output) is required.

Applications

The Allen-Bradley 2711P-B6M1A is ideal for machine control, process monitoring, and data entry tasks in industries such as manufacturing, packaging, and material handling. Its compact size and robust design make it suitable for panel mounting on machinery where space is limited.

For example, in a bottling line, the 2711P-B6M1A can display real-time production counts and allow operators to adjust parameters via the keypad or touchscreen. In a CNC machine setup, it can serve as a dedicated operator panel for tool selection and status alerts.

Installation & Setup

Mount the Allen-Bradley 2711P-B6M1A in a panel cutout following the dimensions of 167mm x 266mm x 98mm. Ensure adequate clearance for ventilation and cable routing. Connect the power supply to the terminal's AC input, observing the specified voltage range. Use the RS-232, Ethernet, or RIO ports to link to the PLC or network. For touchscreen calibration, follow the on-screen prompts after power-up.

Maintenance & Reliability

Regularly inspect the keypad and touchscreen for wear or damage. Clean the display with a soft, dry cloth to maintain visibility. The CCFL backlight has a 50,000-hour standby life, reducing replacement frequency. The internal clock is battery-backed with an accuracy of ±2 minutes per month; replace the battery every 3-5 years to avoid time drift. Operate within the 0-55°C (32-131°F) range and 5-95% non-condensing humidity for optimal performance.

Compatibility & Integration

The Allen-Bradley 2711P-B6M1A communicates via RS-232, USB, Ethernet, and Remote I/O, making it compatible with Rockwell Automation PLCs and other industrial networks. It supports 256MB compact flash cards (2711P-RC3/2711P-RC4) for data logging. When integrating, verify the communication protocol matches your controller's settings.

Buying Guide

Before purchasing the Allen-Bradley 2711P-B6M1A, confirm your system's power supply and communication requirements. Since this model is discontinued, source from reputable suppliers like PLC Source PRO to ensure genuine parts and reliable service. Check the unit's condition and compatibility with your existing PanelView Plus software.
