Question 111/144

Time Delayed DC 12V Remote Unit with Manual Switch to control a Specific Appliance

Question:

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 seconds 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.

Let’s see practical use. Here is the transmitter and manual switch wiring.

We switch on the manual switch and the transmitter will send an “ON” signal to the receiver. The receiver receives the signal to instruct the light to turn on. We switch off the manual switch and the transmitter will send an “OFF” signal to the receiver. Owning to the time delayed program, the receiver won’t give response to transmitter. After 15~20 seconds, the receiver will instruct the light to turn off. (The delay time is preset according to your requirement.)
