2-channel 433MHz RF Receiving Relay Module - AK-RK02E - 12-48V 10A

2-channel receiver relay module for 433MHz RF control. The maximum load of each channel is 10A at 230V AC or 30V DC.
It will work wherever we need wireless control of switching on and off electrical devices, roller shutters, lighting, entrance and garage gates for modifying industrial controllers, access control and many others. The relays have 4 operating modes:
I The relays are activated for as long as the remote control button is held.

II After receiving the impulse from the remote control, the relay switches and stores the state, another pressing with the second button of the remote control disconnects the relay.

III After pressing, the relay switches on, and when the same button / channel of the remote is pressed again, the relay disconnects.

IV After receiving the signal, the relay switches on for 5 seconds and then switches off.

The radio link module can store 20 different codes.
The module is equipped with a dedicated RF 433MHz remote control.

Programming:

The module has two labeled buttons, the first is Mode, and the second is Learning, i.e. learning - the remote control. First, we teach a specific button / remote channel / code. For this purpose, by pressing the button once, we program the first relay, which the LED confirms with single flash. During this time, we press a specific remote control channel, the module confirms that the code has been saved when the LED starts flashing quickly and then goes off. If we click the button twice, the pilot learning mode is for the second relay, which is confirmed by the controller by double blinking.

When we program a specific button for the remote control, then we set the operating mode. One click of the MODE button confirmed by one blink of the MODE diode means 1 mode: the relay is on as long as the button in the remote control is held. Double clicking and confirming with two flashes is the second mode, i.e. the relay is turned on with one button and turned off with the other (a 4-channel remote control is needed, the so-called state memory). 3 mode - the relay is switched on and off with one button - state memory. 4 mode, the relay after switching on maintains the state for 5 seconds and disconnects.
