Relay User Manual
Updated January 27, 2021
Relay is a wireless, low-voltage relay featuring potential-free (dry) contacts. Use
Relay to remotely switch on/off appliances powered by a 7–24 V DC source. Relay
can operate both in pulse and bistable mode. The device communicates with a hub
via
Jeweller
radio protocol. In the line of sight, the communication distance is up to
1,000 m.
Regardless of the type of electrical circuit, only a qualified electrician should install Relay!
The Relay contacts are not galvanically connected to the device itself, so they can
be connected to the input control circuits of various equipment to imitate a button,
toggle switch, etc.

  • Page 3: Operating Principle

    Relay terminals — output potential-free terminals. Operating Principle Do not connect Relay power supply input terminals to a voltage exceeding 36 V or alternate current sources. It creates a risk of fire and will damage the device! Regardless of the type of electrical circuit, only a qualified electrician should install Relay! Relay is powered by a 7–24 V DC source.
  • Page 4 Relay operation modes: Bistable — Relay opens or closes contact and remains in this state. Pulse — Relay opens or closes contacts for a pre-set time (from 0.5 to 255 seconds) then switches back to the initial state. Connecting to the hub Before connecting the device: 1.
  • Page 5 (at the same object). The connection request is transmitted only at the moment of switching on the device. If the device failed to pair, wait 30 seconds and then retry. Relay will appear in the list of hub devices.

    2. Connect the grid wire to the Relay terminals according to the following scheme: When installing Relay in the box, lead out the antenna and place it under the plastic frame of the socket. The bigger the distance between the antenna and metal structures, the lower the risk of interfering (and impairment) of the radio signal.

  • Page 9: Maintenance

    During the installation and operation of Relay, follow the general electrical safety rules and the requirements of electrical safety regulatory acts. It is strictly forbidden to disassemble the device. Do not use the device with damaged power cables. Do not install the relay: 1.
