The KNX-GW-MBUS SK08 is a device that can integrate all kind of consumption measuring devices that are equipped with an M-Bus interface into the KNX-bus.
The bus coupler is a three times bus master of the M-Bus interface according to DIN EN 13757-2/3. Each of the three ports provides an M-Bus master that can read one M-Bus device. The advantage lies in an M-Bus ID independent device discovery.
( broadcast adressing ).
There are 32 M-Bus data points available, which can be assigned freely to the different devices
The device has an integrated bus coupling unit and needs no auxiliary power.
The KNX-GW-MBUS SK08 is delivered in a high-strength, extremely robust stable impact ABS plastic housing. Cover and base have a revolving groove and tongue system with neoprene gasket and achieves the protection class IP54/65.
The KNX-GW-MBUS is set up using the ETS ( KNX Tool Software ) and the applicable application program.
- Integration of Meters and Consumption counters into the KNX-bus
- Acquisition and communication of consumption data in KNX environments
- Retrofitting of existing M-Bus installations
