ems4.SM04E

Communication interface for the integration of M-Bus

The module ems4.SM04E is used for the direct readout of up to 60 MBus-compatible meters (e.g. heat meters, water meters, electricity meters, pulse counters, etc.). The integrated MBus level converter saves the use of additional components. Once configured, the primary address, bus speed and readout frequency of the connected meters are parameterised; the ems4.SM04E then takes over the self-sufficient data communication.
