The 4 channel wireless relay module is a smart module with 4 mechanical relays providing an easy way to control large AC and DC loads and device. With the 315MHz RF receiver integrated in, it can be directly remote controlled by the matching remote-control, which make it easy to use in home automation and industry control. The remote-control has its own battery, the relay receiver board must be provided with 12V DC supply to get it work. Rated load of the each relay on the receiver board is 10A/120VAC 20A/14VDC.
It also provides three alternative provisions to meet demands in different situation simply using the jumper selection.
Unlock mode锛欽umper 1 and Jumper 2 are diselected. Hold down the button for relevant relays closed until you released it.
Lock mode: Jumper 2 is selected. Push the button for relevant relays closed until another button pushed.
Delay mode: Jumper 1 is selected. Push the button for relevant relay closed for two second.
In open area and without any interference, this set is rated to detect no more than 100 meters in theory with the transmitter antenna extended. If you are in the house, the transmission distance is about 10%-50% distance in theory according to the walls and interference.
If you don’t know much about relays, research using your multimeter.聽 It is just an electro-mechanical switch.
