M-Bus Master / KNX rajapinta

Product number: EK-BM1-TP-20

The Ekinex® M-Bus - KNX Gateway performs a protocol conversion between an M-Bus and a KNX TP network. The device acts as M-Bus master. Versions for networks with a maximum number of 20, 40, 80 and 160 connected M-Bus slave devices are available. The device integrates a KNX bus communication module and it is suitable for mounting on a 35 mm DIN rail; it requires an auxiliary power supply.

EK-BM1-TP-20 key features:

Technical data:
– Power supply: from M-Bus network
– Absorption at 24 Vdc: 3,5 VA (without load); 4, 5, 8 or 14 VA (resp. with 20, 40, 80 or 160 M-Bus devices)

Communication KNX side:
– KNX TP (Twisted Pair) communication port electrically isolated from power supply
– Baud rate 9600 baud
– 1440-byte volatile support “KNX image” memory buffer

Communication M-Bus side:
– M-Bus communication port (wired version, two-pole cable)
– Selectable baud rate from 300 to 9600 baud
– Device addressing from 1 to 250
– Variable reading through M-Bus slave device mapping
– 1440-byte volatile support “M-Bus image” memory buffer

– Ethernet communication port (IEEE 802.3), RJ45 connector, minimum cable category: 5E

Other information:
– M-Bus (Meter-Bus) is a standard protocol for remote reading of data acquired from thermal energy, electricity, gas and water meters. M-Bus is fully compliant with EN 13757: Communication Systems for remote meter reading, parts 2 (Physical and connection layer) and 3 (Application layer).
