M-Bus Master - KNX gateway

DIN-Rail mount modules

CODE: EK-BM1-TP-20

Description

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.

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
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
Configuration

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

Delivery

The delivery includes the device and terminal blocks to connect to the KNX bus.

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).
