433MHz 24V 4 Channel Relay Module Wireless with RF Remote Control Switch433MHz 24V 4 Channel Wireless Relay Module with RF Remote Control A wireless remote can operate a switch that does not have a battery through a wireless RF connection. The relays may be used to regulate 240 V AC appliances, motors, other electrical circuits, and so on. The board has a range of 50m when the remote is in line of sight and roughly 25m while inside. This board's RF connection operates at 433 MHz. Both the transmitter and receiver have an
