This 4 relay dc rf wireless memory remote control system operates in toggle, momentary, latched, toggle + momentary control mode (set the mode as you like freely). With function of memory, if the power is cut off, the relay will return automatically to the previous status after the power is restored. Widely used to control lights, motors, fans, electrically operated doors / locks / windows / blinds / cars or other appliances with voltage AC110~240V or DC0~28V.
Control Lights, Motors, Fans, electrically operated Doors/Locks/Windows/Blinds/Cars or Other Appliances with AC110~240V or DC0~28V.
You can turn on/off the receiver with transmitter (remote control) from any place within a reliable distance; the wireless RF signal can pass through walls, floors and doors.
With characteristics of reverse power protection and over current protection
Audible / visual indication
Use microcontroller model of EM78P156, an 8-bit microprocessor designed and developed with low-power and high-speed CMOS technology.
Reliable control: The transmitter (Encoding) and the receiver (Decoding) use an 8-bit code.
One/several transmitters can control one/several receivers simultaneously.
If you use two or more receivers in the same place, you can set them with different codes.
Transmitting Frequency: 315MHz / 433MHz
Function of memory: If the power is cut off, the relay will return automatically to the previous status after the power is restored.

The theoretical distance is 100m, which shall be operated in an open ground; no barriers and no any interference. But in actual operation, it is hindered by trees, walls or other obstacles, or interfered by other signals. Therefore, the actual distance can not reach 100m. If you need longer range, please choose other series of remote control, such as CB Serie (1000m/3000ft) - Click here; Or you can add the External Extend Antenna (model: 0020909) on the receiver to extend the range - Click here.
