Application

  • Extension of M-Bus communication line over the standard distance (suitable for cca. over 1km).
  • Galvanic separation of individual M-Bus line sections.
  • Splitting of M-Bus line into multiple electrically independent branches.
Designed for use in industry, building automation and other similar applications for remote M-Bus data readout.

Description

The repeater splits the M-Bus line into two galvanically separated M-Bus lines and enables message transfer between these two lines without message content changes. In case of a malfunction state on the M-Bus line (e.g. a short) this state willl not be carried over to the second separated line. On the primary line the repeater acts electrically as 2 slave devices (2 UL) - slave port. The separated line uses a standard M-Bus master port. Depending on repeater model the M-Bus master port has a connection capacity for 45, 80, 120 or 190 M-Bus devices.

Main characteristics

The M-Bus repeater features a processor controlled monitoring of internal state, power supply state and M-Bus master port state. Operation and error states are indicated by status LEDs which simplify and make it easier to troubleshoot possible M-Bus communication errors.
M-Bus master port
  • Connection of 1 to 45, 80, 120 or 190 M-Bus slave devices depending on converter model.
  • Surge protection warranting above standard level of protection against overvoltage.
  • Current protection against overload and short circuit on the communication line.
  • External voltage protection.
  • Processor controlled monitoring of M-Bus line state with LED indication for various error states.
  • Indication of M-Bus slave devices reply collision.
  • Indication of slave devices presence on the M-Bus line.
  • Indication of M-Bus line overload, short and capacitive overload.
Power supply
  • Wide range of operating DC power supply voltages 12-30V (20-30V for the XL190 model).
  • Over voltage protection.
  • Processor controlled monitoring of power supply voltage with indication of its correctness and errors.
M-Bus slave port
  • Power consumption as 2 slave devices (2UL).
  • Over voltage protections.
  • Galvanic separation from power supply and M-Bus line.
Mechanical construction
  • Aluminium box with mounting on 35 mm DIN rail.

Guarantee of quality

  • Each converter passes through several functional electrical tests during the production.
    Additionally a communication test is performed after final assembly.
  • EMC certification in an accredited laboratory for industrial environment.
  • Solid design and construction based on many years practical experience.
