Supplier's note

  1. Technical Breakthroughs:

    • High Load Capacity: The Pro Model’s 10A/250V rating exceeds industry standards by 30%, enabling safe control of heavy-duty appliances like industrial pumps.
    • Enhanced Isolation: The Pro’s 1,500V isolation voltage (vs. 500V in Base) prevents cross-channel interference in high-voltage environments.
    • Global Compliance: Full EU/US certifications in the Pro Model reduce regulatory hurdles for commercial deployments.

  2. Version Selection Guide:

    • Base Model: Ideal for hobbyists or low-power projects (e.g., LED lighting, small sensors).
    • Advanced Model: Suitable for moderate industrial use (e.g., motor control in robotics, HVAC systems).
    • Pro Model: Best for high-stakes applications requiring extreme durability and compliance (e.g., factory automation, medical equipment).

With the Pro Model’s triple-isolation design, you can safely handle corrosive environments while maintaining signal integrity. Pair its 10A capacity with FR4 PCB stability to ensure long-term reliability in harsh conditions.
