    Product Character

          This is an RF remote control subsystem with 2-button transmitter and 2 relays built inside the system with rolling code. It’s the active low type. Major application is for the garage opener remote control. You can also use it as a general-purpose remote control system to control many applications around your home or for other hobby projects. You can add up to 15 transmitters per system. 

    Each model can be independently programmed to set the relay output mode as follows:

    • Pulse type:

    The activated relay will be closed for 2 seconds for each activation. This is the most widely used application such as garage opener. 

    • Sustaining type:

    The activated relay will be closed for as long as the transmitter button is held down. You can connect it to a buzzer so that the buzzer will sound for as long as the transmitter’s button is down. 

    • Latch type:

    The activated relay will be closed until you push the button again. You can use it to control a 110V or 220V AC lamp or appliance by connecting through a suitable external strong AC-relay first. Push the transmitter’s button to turn the lamp or the appliance on. Repress the button will turn it off.
