315MHz Remote Relay Switch Kits 2 Channels

**5MHz remote relay switch kits - 2 channelsThis remote switch allows you to remotely control any *2 Volt DC device. Perfect for controlling any *2V devices such as Lights, Fans, Landscaping Lighting and more. This easy-to-wire kit is perfect for anybody with a basic knowledge of electrical wiring, and can easily be wired to many *2V applications. For PC Moders, the end of result of the Remote Control *2VDC kit are truly impressive and are sure to ooh and ah the crowds. For DIY lovers, the kit will give some magical effect to your projects. 1Transmitter module: Special Parameter: Frequency: **5MhzModulation: ASKWorking Voltage: *2VDCFrequency differencemin± *5kHz max± **0KHzLaunching power: *0mW(*2V)Working current*0mA*2VFrequency stability: 0.**7ppm/Temperature range****-**5Transmission rate: *0KbpsEncoder: PT***2Timing resistor1.5MReceiver Sensibility: ***5dbmEmission Distance: **0m in open groundSize: *7 X *3 X 8mmThis module have been pinout All data interface, convenient for useage, and only when more than one data bits among *0 ~ *3 four data bits are high electricity level, the module will transmit the high frequency signal. 2Receiver module: Relay Operation Modes: The receiver has three modes that control how the relay outputs function. These modes are user selectable using the 3 pin jumper on the receiver. Momentary: Move the switch position to M? ? ? To set the selected relay(s) in momentary mode. In momentary mode, the selected relay(s) will change its state and maintain it for the duration of the transmission received. Once the transmission is terminated, the relay will change back to its original state. Flip-Flop: Remove the shunt to set the selected relay(s) in Flip-Flop mode. In Flip-Flop mode, the selected relay(s) will change its state and maintain it until a matching transmission is received. Every time a transmission is received the relay will change its state and maintain it until another transmission is received. Latching: Move the switch position to L? ? ? 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 **5MHz RF link. On the transimitter side, You would need to supply ***2VDC to the "**2V" pin, and set "VT" high to enable transmission. On the receiver side, you may use *5VDC(aka VCC) for power and read the output from D0~D3. "VT" will indicate thenever there is changed data incoming. Encoding and Decoding: The popular link is like this: MCU -> Encoder -> Transmitter *****- Receiver -> Decoder -> MCU, PT***2(Encoder) and PT***2(Decoder) are optional, their existence is to 1)avoid confusing when multiple RF links in range 2) isolate disturbance. You can integrate the encoding and decoding work to the MCUs on both side. Whenever there is no **5MHz devices around, you may use it as direct cable connection. This multifunction AC double relay receiverpower from AC **0V, it can control A and B two load at the same timeand it can switch channel bt jumper wireyou can try to change the situation of the AB jumper wire cap to grope concrete corresponding channelThis multifunction AC double relay receiver use SCM to be control chipso the working mode can change flexibllyit can work in latchcrawltrigger modelatch mode: Link the pin 5 of EM*8P**3 to GNDcrawl mode: Link the pin 6 of EM*8P**3 to GNDtrigger mode: Not link the pin *6 of EM*8P**3 to GNDYou will correct the code before usethe method is simpleafter link Land N to **0V AC powerthen push the white .
