Wireless M-Bus repeater 230vac for indoor use

Wireless M-Bus repeaters are intended to retransmit data from wireless M-Bus meters or sensors. This is often needed inside big buildings, where meters are with wireless M-Bus.

Since wireless M-Bus is on the 868 MHz frequency, it is dependent on distance and obstacles. Usually around 300-400 metres of direct view is not a problem, but building materials and sensor/meter position are also very important. In order to use only one main collecting concentrator in bigger buildings, users must use signal repeaters. That is what our repeater does: retransmit with full power possible all meters that are in range. Our repeaters do not change received telegrams except for setting the ‘repeat’ bit in the status byte.

There is no hop limit or meter number limit. Basically the device is ready to work immediately after being powered. But if the user wants to limit or filter repeated meters, this also can be done, because our repeater has smart functions like filtering due to the medium measured, manufacturer or special list of IDs. Our WMBRP repeaters work by default in mode T but, of course, can be set to modes S and C without a problem. Setting is through the air, using a wireless master device and our service software.
