RBF Relay is a dry contact relay to control 6-36 VโŽ“ power supply remotely.



  • Physical button control
  • App Control
  • Smart Scene control: By Alarm, By Operation, By Fault, By Schedule

Remote setting and testingโ€‹

  • Setting and testing from RB Link App

Advanced featuresโ€‹

  • Power up enrolling

    When sensor is powered up, it will automatically start paring to the hub nearby

  • Find me

    When enabled, the device starts flashing green, which can help identify the sensor from numerous door magnetic sensors.

  • Signal strength detection

    When enabled, relay starts flashing green/orange/red showing the wireless signal strength between the hub at current installation place.


  • Relay ON: Blue indicator is On
  • Relay OFF: Blue Off
  • Find me: Flashing Green
  • Signal strength:
    • Flashing Green: signal strength is strong, and is recommended to install device here
    • Flashing Orange: signal strength is medium and device can be installed here
    • Flashing Red: signal strength is bad or no signal, and device can not be installed here

RBF wireless technologyโ€‹

Wireless signal rangeโ€‹

  • Up to 1,900 m in an open space with hub
  • Two-way communication between hub

Frequency bandsโ€‹

  • 868 MHz Relay: 863 ~ 870 MHz

  • 915 MHz Relay: 902 ~ 928 MHz

    Depends on sales region.

Maximum effective radiated powerโ€‹

  • Up to 20 dBm

    Featured automatic power control to reduce power consumption and noise interference.

Wireless signal modulationโ€‹

  • FSK / DSSS

Encrypted communicationโ€‹

  • All the data transmitted are protected by AES-CCM encryption with a random key.

Frequency hopping (FHSS)โ€‹

  • To prevent radio interference and radio signal interception.

Time division multiple access (TDMA)โ€‹

  • With the help of clock synchronization technology, hub will slice time into different division for different RBF wireless devices. In this way, all devices will communicate with hub in a sequence.
