A ready-made set of radio relays is designed for remote switching of electrical circuits with currents up to 250V/10A, such as gates, lifts, small heaters, starters, electric locks. Ideal for integration into a car system, as it can be powered from 12V. The set includes a protective box-case with latches.
Pressing the button on the key fob turns on the relay. Since the contacts NC, NO, COM of the switching contact of the relay are taken out, by connecting to the desired contact, you can both close and open the circuit. The range is up to 50m, indoors up to 15m, depending on the "noise" of the radio and weather conditions.
The receiver module can work with several remotes and in several modes: momentary, hold and latch. Several remotes can be assigned to each mode.
1. Short-term - the relay is switched while the button on the remote control is held.
To program on the receiver, briefly press the button once, when the LED lights up, press the button on remote control, the LED on the receiver should blink and go out, the button is added to the module memory. If you need to add several remotes, you need to repeat this operation.
2. Hold - when you press the button on the remote for the first time, the relay switches. When the same button is pressed a second time, the relay returns to its original position.
To program on the receiver, you need to briefly press the button twice, when the LED lights up, you need to press the button on the remote control, the LED on the acceptance should blink and go out, the button is added to the module's memory. If you need to add several remotes, you need to repeat this operation.
3. Latch - when you press one button on the remote control, the relay switches, when you press another button, the relay goes into its original state. This mode requires a lot of keypad or two one keypad.
To program on the receiver, you need to briefly press the button three times, when the LED lights up, you need to press one button on the remote control, then the second, the LED on the acceptance should blink and go out , buttons are added to the module memory. If you need to add several remotes, you need to repeat this operation.
To erase all remotes from the device memory, you need to press the button 8 times, the LED will blink and go out, the remotes are erased.
You can use remotes with encoders PT2260, eV1527 and their analogs ...
