HD67020-B2-3

MBus to RS-232 converter (Master MBus: up to 3 slaves), housing type B (wide), DIN rail mount.

This series allow to read/write M-Bus Slaves devices by RS232, ensuring galvanic isolation between M-Bus and RS232. HD67020 is a Plug&Play device and it allows to connect up to 3 M-Bus Slaves to RS232. The converter does not require any configuration. The baudrate is automatically detected at RS232 side and used (the same) to the M-Bus side.

Characteristics:

• Electrical isolation between RS232 and M-Bus
• 35mm DIN rail mount
• No configuration software needed
• Overcurrent and short-circuit protection on the M-Bus
• Baudrate: from 300 to 38400, Parity: None, Odd, Even

Specifications:

• Ports: 1x MBus; 1x RS-232
• Data Rates MBus: Up to 38400 bps
• Data Rates RS232: Up to 38400 bps
• Power supply: 15...21V AC; 18...35V DC
• Operating temperature: -40°C/+70°C (-40°F/+158°F)
• Dimensions: 36x60x95mm (DxWxH)
• Weight: 200g approx
• Maximum power consumption at converter start-up: 30W
• Mechanical fixing: DIN Rail mountage
• ORDER CODE: HD67020-B2-3

Manufacturer's warranty: 24 months

MBus (Meter-Bus) is an European standard for remote reading of wide range of consumption meters. As long as MBus has both physical and application layer in most cases there is a need for external protocol/electrical layer converter to read MBus meter. Converters with MBus interface are used to read the data from gas meters, energy meters, water meters and others.
