This dc rf remote control kit 0020522 (S1L-DC12-ANT2 & CB-2N) can be used in such a situation when you want to use an electrical device to remotely control another device. It features in long remote distance, up to 2000m (in open field).
How does it work? Here we will go into details.
First let's see the remote controller. There are two extended wires on the remote controller. With the connection and disconnection of two wires, the remote can send out rf wireless signal “ON” and “OFF”. The receiver is for receiving the signal.
The remote can be connected to the original electrical device and the receiver connected to the devices being controlled. When the original device is turned on, the device being controlled will be turned on automatically.
We take led light as the device being controlled. It is connected to the receiver. But in order to make operation look simple, the remote is not connected to any electrical devices.
According to wiring pictures, solder the negative wires of power supply and led light together. Connect the positive wires of that power supply and led light to the normally open contacts (B&C) on receiver. The receiver also need the power to work, so connect another power supply to the receiver.
Plug two power supplies to the power socket.
Switch on the power. If two extended wires on the remote are connected, the remote is triggered and then transmits an“ON” signal to the receiver. After the receiver receives the signal, the relay is connected; led light will be turned on automatically. Long sentences to describe the operation but the whole process is just in a second.
If two extended wires are disconnected, the remote is triggered and then transmits an “OFF” signal to the receiver. After the receiver receives the signal, the relay is disconnected; led light will be turned off.
