We recommend 1 channel 110V~220V customized delay time controller (S1RD-AC220+C-2). At first, it must be set delay time in advance. According to your own actual requirement, you can set delay time you want. e. g. delay time: 20 seconds. You cannot change delay time once it is set. It is applied for controlling lights, motors, fans, electrically operated door/ lock/windows/ blinds/ cars or other appliances with AC 110~240V or DC 0~28V. You can turn on/off device on the receiver with transmitter from any place within reliable distance (theoretical distance 100m), the wireless RF signal can pass through wall, floors, doors and other obstacles.
