4. Wiring

  • Connect +12V to the relay module and the main controller.
  • Connect GND to the relay module and the main controller (common ground).
  • Connect Live (L) to the COM terminal of each relay output.
  • Connect the NO (Normally Open) terminal to the load (e.g. light, motor).
  • When the relay is activated, power flows from COM to NO to energize the load.
