How to use

Install the module inside a suitable enclosure or directly onto a control board, ensuring correct electrical isolation and secure mounting. Connect power supply and the load to the relay terminals according to the product's wiring diagram and observe the relay's rated load limits. Pair or configure the module with compatible 433 MHz transmitters or control units following the manufacturer's pairing procedure. After installation and pairing, use the remote transmitter to toggle the relay for on/off control of the connected device.

Usage recommendations

Use the module within its specified supply and load ratings, and provide adequate surge protection when switching inductive loads such as motors or solenoids. Place the unit away from large metal obstructions to improve RF reception and follow safe wiring practices when integrating the module into mains-powered circuits. For permanent installations, mount the module inside a protective enclosure and, where required by regulations, have electrical connections performed by a qualified technician.
