Overview: “I am looking for a remote and multiple receivers for a small private airport. We have a controller box switch that activates when you key the microphone 7 times on a specific frequency. I would like to plug a dc power adapter into this unit and wire into one of your remotes. The runway lights are all solar dc leds. I will need 12 receivers total to start out. My question is: Can one remote, controlled by external wires, send a signal out to multiple receivers at the same time?  In other words, if the remote detects dc input and sends out an ON signal, can several receivers receive the ON signal at the same time?” Solution: We recommend the low voltage triggered transmitter (CB-2V) and 1 channel 2000m receivers (S1L-DC12-ANT2). The most remarkable feature of this transmitter is low current triggered. That is to say, when you offer dc power 5~28V to this transmitter, it will send signal out to the receiver. The receiver is long range with external extended anten...

Question from customer: Hello, I have a question about your products and a system I’m attempting to build. I have four sensors that give off about 5 volts when activated. When a sensor is activated I want to transmit a signal to a light and turn on a light. The basic design is: Sensor —> Transmitter  –>(Wireless)–> Receiver —> Light What I’m asking is what transmitter could I use with the 4 Channel Receiver? Would I need 4 separate transmitters for each of the sensors? Answer: We recommend the low current triggered transmitter (CB-2V) and the ac power direct output receiver (S1X-AC220). The transmitter is triggered by DC power 5~28V input. If low current input triggers transmitter, the transmitter will send RF signal to receiver to indicate it to work. The receiver has 1 Channel AC 110V/220V Power Output terminal contact. You don’t have to supply addition power to controlled device because the device will get power from powered ...
