Supplier's note

  1. Technical Breakthroughs:

    • High-Capacity Storage: The 4MB Pro Model offers triple the capacity of industry-standard 1MB cards, enabling storage for complex PLC programs.
    • Extreme Durability: Temperature tolerance up to +85°C exceeds competitor benchmarks by 15%, ensuring reliability in foundries or chemical plants.
    • Military-Grade Security: The Pro Model’s encryption prevents data breaches, critical for sensitive industrial applications.

  2. Optimal Version Selection:

    • Base Model (128KB): Ideal for small-scale automation tasks (e.g., basic HMI controls) where cost efficiency is prioritized.
    • Advanced Model (2MB): Suitable for mid-sized systems (e.g., conveyor control lines) needing expanded program storage.
    • Pro Model (4MB): Recommended for large-scale operations (e.g., chemical processing plants) requiring high program complexity and data security.

With the Pro Model’s 4MB capacity, you can store advanced ladder logic programs for smart factories. Its +85°C tolerance ensures stability in high-temperature environments, while military-grade encryption secures intellectual property. Pair the Advanced Model with vibration-resistant mounting brackets for robotic assembly lines to maximize uptime.
