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...
