  🔌 Wiring & Usage

  1. Control Connections (5V Logic)

  • VCC: Connect to 5V power supply (for optocoupler).

  • GND: Common ground (shared with control signal).

  • IN: Signal pin – Pull LOW (0V) to activate relay.

  2. Load Connections (Terminal Blocks)

  • AC/DC Load (+): Connect to one side of the load.

  • AC/DC Load (-): Connect to the other side.

  ⚠ Warning:

  • Do not exceed 2A load current (risk of overheating).

  • For AC mains wiring, follow safety precautions (insulate properly).
