Question from customer: The transmitter is to function as a switch to the receiver activated by supplying a 12v DC current to the transmitter (switching it on). The receiver then permits a 12v DC current to be supplied to a specific appliance. When the transmitter is shut off the receiver should have a 15 to 20 second delay before stopping supply to its appliance which will then shut down. Answer: We recommend this kind of controlling unit — 12V time delayed receiver and low voltage triggered transmitter (S1X-DC12-ANT2+CB-2V) to you. It is applied for device controlling another device. The remarkable characteristic of the transmitter CB-2V will be triggered by DC power 5~28V input. That’s to say, when you give voltage of 5~28V to the transmitter, transmitter will be on. We add external extended antenna whi...

Question from customer: I want a remote controlling unit that the transmitter is to function as a switch to the receiver activated by supplying a 12V DC current to the transmitter (switch it on). The receiver then permits a 12V DC current to be supplied to a designated appliance. When the transmitter is shut off the receiver will shut down. Answer: Maybe this kind of controlling unit — 12V power Input RF remote control system (S1XL-DC12-ANT2+CB-2V) is suitable for you. It is applied for device controlling another device. The characteristic of the transmitter CB-2V will be triggered by DC power 5~28V input. We add external extended antenna which makes transmitting distance up to 2000m. According to the picture above, he wants the transmitter can be activated by manual switch and turn receiver on/off when the current in that circuit is on/off. First, the transmitter is supposed to be connected to power supply and that manual switch. Second, designated appliance should be connec...

Do you want to use one existing device to control another device remotely? Maybe that will be more convenient to you on some special ccasion. In fact, we have a completely new product low voltage triggered great range transmitter of CB-2V which is applied for one device controlling another device. This transmitting module will be triggered by DC power 5~28V input. We really hope this kind of remote can satisfy customers’ needs. We think our product can meet his need. According to his requirement, that transmitter can work   with dc 12V 1 channel latched long range receiver model of 0020522 S1L-DC12-ANT2. He said that the relay, which is activated by receiver, needs low voltage and current. Working voltage range of relay can be DC 0~28V.  So this receiver is more favorable for him.     Let’s study the wiring diagram. That is fairly simple. Existing device is connected to the positive and negative terminals of the transmitter. The device being contr...
