M-Bus to RS485 Converter


The products of the HD67022M series are level converters that allow the communication between a PC/PCL and the Slaves M-Bus.

The serial used for the connection with the PC/PLC is a RS485.

The use of RS485 is recommended because this link allows to have the PC, or other system, at a distance of 1200m from the level converter, unlike the RS232 where the recommended maximum cable length is 15m.

The HD67022M allows to develop the own software for register and process the data (for example for the charging users); or use the existing programs.

The M-Bus is able to power up to 250 slaves.

The microprocessor control guarantees a stable communication with the M-Bus slaves.

Delivery in approximately 2-5 working days (subject to availability)
