Description
Product Name: 2711-B5A8L3 Allen Braley Output module
Product details:
The Allen-Bradley 2711-B5A8L3 is a member of the PanelView 550 series of Human-Machine Interface (HMI) terminals. While this specific series has been largely superseded by newer lines like the PanelView Plus, it remains a critical component in many legacy industrial automation systems.

3. Product Advantages
-
Dual Input Control: Combines a touchscreen for intuitive navigation with a physical keypad for high-precision input or use while wearing gloves.
-
Rugged Design: Built to withstand harsh industrial environments, including vibrations, temperature fluctuations, and exposure to dust/moisture.
-
Compact Footprint: The 5.5-inch screen allows for installation in tight control panels where space is limited.
-
Reliability: Known for a long service life and high “Mean Time Between Failures” (MTBF), making it a staple in long-term manufacturing setups.
4. Key Considerations & Precautions
-
Legacy Status: This model is considered a legacy product. Sourcing brand-new units may be difficult, and most available stock consists of refurbished or “New Old Stock” (NOS) units.
-
Communication Protocol: The DH-485 protocol requires specific cables (such as the 1747-C10/C11) and compatible PLC ports (typically SLC 500 or MicroLogix series).
-
Voltage Sensitivity: Ensure the power supply is a steady 24V DC. Using AC power or incorrect DC voltage will cause permanent damage to the internal circuitry.
-
Software Compatibility: Programming typically requires PanelBuilder32 software, which may require older Windows operating systems or virtual machines to run correctly on modern PCs.
5. Product Applications
The 2711-B5A8L3 is widely used in industries requiring reliable, real-time data visualization:
-
Manufacturing: Monitoring assembly line status and motor speeds.
-
Food and Beverage: Controlling temperature and pressure parameters in processing equipment.
-
Water Treatment: Managing pump stations and flow rates.
-
Material Handling: Operating conveyor systems and sorting machinery.
