This remote switch allows you to remotely control any 12 Volt DC device. Perfect for controlling any 12V devices such as Lights , Fans, Landscaping Lighting and more. For PC Modders, the end of result of the Remote Control 12VDC kit are truly impressive and are sure to ooh and ah the crowds.
- Frequency: 315Mhz.
- Working voltage: 12VDC
- Receiver sensibility: -105dbm
- Emission distance: 100m in open ground
- Size: 68mm*47mm*12mm
Each Relay owns one group of 3 pins:
Relay Operation Modes:
And setup the corresponding pins on PT2272:
The receiver has three modes that control how the relay outputs function.Momentary:
Move the switch position to set the selected relay(s) in momentary mode. Flip-Flop:
Remove the shunt to set the selected relay(s) in Flip-Flop mode. Latching:
Move the switch position to set the selected relay(s) in Latching mode. In latching mode, when the selected relay is activated by the transmitter, that relay will change its state and maintain it until power to the receiver is removed or interrupted.
Please refer to the simple drawing for the 315Mhz RF link. On the transimitter side, You would need to supply 3-5VDC to the "+12V" pin,(Caution: the 12v is an error silk screen on PCB, never give it more than 5V
, and set "TE" high(5V) to enable transmission. On the receiver side, you may use +5VDC(aka VCC) for power and read the output from D0~D3. "TV" will indicate thenever there is changed data incoming.
