M-Bus Slave, plint 15-18
The PiiGAB M-Bus 900S contains two separate M-Bus slave inputs. By using these two M-Bus
slave inputs it is possible to connect to external M-Bus masters. These connections are
completely galvanic isolated from each other and from the earth feed. Each input uses less than
one M-Bus load (1.2 mA). The configuration of the inputs is made via the web interface.

The slave inputs is working with communication speed 300, 2400 and 9600 baud.
