Allen Bradley 2711-B6C8L1 PanelView 600 Color Keypad and Touchscreen Terminal

Product Overview

The Allen Bradley 2711-B6C8L1 functions as a high-performance Human-Machine Interface (HMI) within the PanelView 600 series. It features a 5-inch active-matrix color display that provides crisp visualization of machine states and process variables. This specific model utilizes a dual-input configuration, combining a rugged keypad with a responsive touchscreen to accommodate different operator preferences and environmental demands. Equipped with Data Highway Plus (DH+) and an RS-232 printer port, the 2711-B6C8L1 facilitates seamless communication with SLC 500 and PLC-5 controller networks, acting as the primary control point for localized industrial automation.

Technical Specifications

Engineering Advantages

• Hybrid Dual-Input Control: The 2711-B6C8L1 integrates both a tactile keypad and a touchscreen. This design solves the common industrial problem of screen degradation; operators can use the keypad for high-frequency numerical entries and the touchscreen for intuitive menu navigation, extending the mechanical life of the interface.

• Specialized DH+ Networking: This terminal contains a native Data Highway Plus (DH+) interface. It connects directly to legacy Allen Bradley networks without requiring external protocol converters or bridges, maintaining high-speed data exchange with existing SLC and PLC-5 architectures.

• Optimized for DC Power Environments: The unit operates on a wide 18–32V DC input range. This eliminates the need for internal AC-to-DC conversion, reducing heat generation inside the control panel and allowing direct integration into 24V DC industrial battery backup circuits.

• Rugged NEMA-Compliant Sealing: When installed correctly with its original gasket, the 2711-B6C8L1 achieves a high degree of protection against dust, oil, and moisture. Its 12.13 lb heavy-duty chassis withstands the constant vibrations and electrical noise common in stamping, milling, and automotive assembly lines.

• Hardened Non-Volatile Storage: 240 KB of dedicated memory stores complex application screens and alarm logs without relying on constant battery power. This ensures the HMI retains all configuration data during long-term facility shutdowns.

FAQs

• Is the 2711-B6C8L1 supplied as Brand New?

  Yes. Despite the discontinued status of the PanelView 600 line from the manufacturer, we supply this 2711-B6C8L1 as 100% Brand New, original factory-sealed stock. This ensures you receive a unit with a fresh 2711-NL5 backlight and pristine touchscreen sensitivity.

• Can I replace the backlight if the screen dims over time?

  Yes. The 2711-B6C8L1 utilizes the 2711-NL5 replacement backlight lamp. You can replace the lamp through the rear access panel without disassembling the entire terminal, significantly lowering maintenance time.

• Which communication cable should I use for this model?

  For DH+ networking, use standard twinaxial cable. For the RS-232 printer port or certain programming tasks, we recommend the 2711-NC14 communication cable to ensure proper shielding and pinout compatibility.

• What is the advantage of the L1 suffix in the part number?

  The "L1" designation identifies this unit as a DC-powered model (24V DC). This is critical for mobile applications or modern control cabinets where 24V DC is the standard, as it provides a safer and more energy-efficient footprint than AC-powered versions.
