M-BUS-1 / User Manual
1 DESCRIPTION AND OPERATION
DEVICE DESCRIPTION
The device M-BUS-1 is designed for reading of values from metering instruments via
M-BUS interface and further accumulating and transmitting of this data to the LoRaWAN
network. M-BUS-1 has two 'open-drain' outputs so it can be used as a control device. Also
device has two security inputs.
Converter M-BUS-1 may operate in two modes. Converter can be used for any utilities'
meters and industrial equipment with M-BUS interface while it operates in the transparent
mode. But in the independent poll mode of the metering devices converter can be used only
with the next supported devices:
• Heat meter «Teplouchet-1»
• Heat meter «STE 21 «Berill»
• Heat meter «Danfoss Sonometer 500»
• Heat meter «ELF-M Teplovodomer»
• Heat meter «WESER Heat Meter»
• Heat meter «Kamstrup Multical 801»
• Heat meter «Kamstrup Multical 402»
The converter is powered by a 6400 mAh built-in battery with service life up to 10
years, provided data transmitted once a day. The converter can be powered by the 10...36 V
external power supply.
Quantity of connecting M-BUS devices to the converter is up to 10 at the same time.
For the correct functioning of the converter in the independent poll mode,
it is recommended to connect one-model counting devices to one converter
If you simultaneously use different models of metering devices with a single
converter, you should only use the transparent mode of polling devices
