Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • 4-Channel Remote Control: Enables simultaneous control of up to four devices (e.g., roller shutters, lights, motors) via RF wireless technology, ideal for automating home or commercial systems.
  • 12V DC Compatibility: Designed to handle 12V DC power loads, ensuring reliable operation for applications like automatic doors, security systems, and smart home setups.

Key features

  • 1. Durable Material Construction

    • With a compact plastic enclosure and ventilation slots, ensure reliable operation in high-temperature environments. ~30% better heat dissipation than non-vented designs [Disclaimer: Based on internal testing; actual results may vary].

  • 2. Multi-Device Control Flexibility

    • With 4 independent RF channels, control up to four devices simultaneously (e.g., roller shutters, lights, motors). Supports twice as many devices as standard 2-channel models.

  • 3. Robust Power Handling

    • With 12V DC relays rated for 10A per channel, handle heavy-duty applications like motorized gates or industrial equipment. Outperforms lower-rated 5A models in load capacity.

  • 4. Versatile Application Solutions

    • With customizable code learning/fixed code options, adapt to home automation systems or secure commercial setups. Easily integrates with existing infrastructure unlike non-adaptable systems.

  • 5. Modular Design for Easy Integration

    • With a compact, modular design, install seamlessly in tight spaces or retrofit into existing control systems. Simpler installation compared to bulkier alternatives.
