Product Description

Application

Remote data retrieval from M-Bus devices via the RS485 serial communication line in industry and building automation. The most frequently used M-Bus slave devices are heat, water and electricity consumption meters.

Description

The RS485toMBus-XL converter provides a RS485 to M-Bus interface conversion. There is no change in the content of the messages or communication speed during the conversion. Depending on the converter model the maximum number of M-Bus slave devices that can be connected is 45, 80, 120 or 190.

Main characteristics

The M-Bus converter features a processor controlled monitoring of internal state, power supply state and M-Bus line 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 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.

RS485

  • Signals: Data+, Data- and GND
  • 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.
