Water Pump is Remote Controlled by 2000m RF Receiver and Transmitter

Question from customer:

I am looking for a long range relay to control a water pump. The water pump now is controlled by a float switch (on/off) at the reservoir 800 meters away. I have 120 volts at both locations and a relay to start pump.

Answer:

We recommend the 2000m rf AC receiver (S1PUA-AC220-ANT2) and the long range transmitter CB-2N. The receiver is soldered with external extended antenna, which can make its transmission distance at 2000m/6000ft theoretically. It works between AC 100~240V voltage. The maximum working current is 30amps. There are 315Mhz or 433Mhz at your option. The transmitter is special designed because its triggered method is connection and disconnection of two wires. When two wires are connected, the transmitter is triggered and then transmits an rf signal “ON”. When two wires are disconnected, the transmitter is triggered and then transmits an rf signal “OFF”.

The wiring method of your water pump will be talked next.

A, B terminals are normally open; A, C terminals are normally closed. Wire Water pump motor to A terminal and N terminal. Add wire to connect B&L terminals. Supply AC 100~240V power to receiver. Connect two wires of transmitter to relay you mentioned.

circuit

Usage:

When two wires of transmitter are connected, the transmitter is triggered and then transmits rf signal “ON”; When the receiver accepts the signal, it will make water pump work.

When two wires of transmitter are disconnected, the transmitter is triggered and then transmits an rf signal “OFF”. When the receiver accepts the signal, it will stop water pump.

 

Remote control 3 receivers with external extend antenna by wireless 12 CH transmitter

We recommend the 12 CH transmitter long range remote control 3 receivers here. It is model: 3S4UB-AC220-ANT2 & CB-12. The wireless remote control device includes one transmitter (CB-12) and three receivers (3S4UB-AC220-ANT2). The transmitter has 12 buttons and can  remote control 3 receivers within 2000m/6000ft theoretically at the same time. The each receiver can connect four appliances. So the transmitter will control appliances on/off. The wireless device remote control lights, motors, fans, electrically operated doors / locks / windows / blinds / cars or other appliances with AC110~240V or DC0~28V. For example, you can connect four lamps to each receiver and use the transmitter to remote control lamps on/off.

receiver & transmitterreceiver

Here is the circuit diagram of receiver. You can connect four lamps to B terminal of relays in the receiver. Then supply power to receiver by connecting wires to “L&N” terminal. You press the buttons of transmitter and the lamps will turn on/off by wireless remote control.

circuit diagram

The wireless remote control device has four control modes: toggle, momentary, latched, momentary+toggle. You can choose any one of four control modes. We set toggle mode here. You can operate as the process:

The button 1,2,3,4 remote control receiver 1; button 5,6,7,8 remote control receiver 2; button 9,10,11,12 remote control receiver 3.

 

Press button 1: Turn on lamp 1 of receiver 1 (connect B and C, disconnect A and B)

Press button 1 again: Turn off lamp 1 of receiver 1 (disconnect B and C, connect A and B)

Press button 2: Turn on lamp 2 of receiver 1 (connect B and C, disconnect A and B)

Press button 2 again: Turn off lamp 2 of receiver 1 (disconnect B and C, connect A and B)

Press button 3: Turn on lamp 3 of receiver 1 (connect B and C, disconnect A and B)

Press button 3 again: Turn off lamp 3 of receiver 1 (disconnect B and C, connect A and B)

Press button 4: Turn on lamp 4 of receiver 1 (connect B and C, disconnect A and B)

Press button 4 again: Turn off lamp 4 of receiver 1 (disconnect B and C, connect A and B)

 

Press button 5: Turn on lamp 1 of receiver 2 (connect B and C, disconnect A and B)

Press button 5 again: Turn off lamp 1 of receiver 2 (disconnect B and C, connect A and B)

Press button 6: Turn on lamp 2 of receiver 2 (connect B and C, disconnect A and B)

Press button 6 again: Turn off lamp 2 of receiver 2 (disconnect B and C, connect A and B)

Press button 7: Turn on lamp 3 of receiver 2 (connect B and C, disconnect A and B)

Press button 7 again: Turn off lamp 3 of receiver 2 (disconnect B and C, connect A and B)

Press button 8: Turn on lamp 4 of receiver 2 (connect B and C, disconnect A and B)

Press button 8 again: Turn off lamp 4 of receiver 2 (disconnect B and C, connect A and B)

 

Press button 9: Turn on lamp 1 of receiver 3 (connect B and C, disconnect A and B)

Press button 9 again: Turn off lamp 1 of receiver 3 (disconnect B and C, connect A and B)

Press button 10: Turn on lamp 2 of receiver 3 (connect B and C, disconnect A and B)

Press button 10 again: Turn off lamp 2 of receiver 3 (disconnect B and C, connect A and B)

Press button 11: Turn on lamp 3 of receiver 3 (connect B and C, disconnect A and B)

Press button 11 again: Turn off lamp 3 of receiver 3 (disconnect B and C, connect A and B)

Press button 12: Turn on lamp 4 of receiver 3 (connect B and C, disconnect A and B)

Press button 12 again: Turn off lamp 4 of receiver 3 (disconnect B and C, connect A and B)
