Functional principle

The BL20-E-1SWIRE supports the connection

of one SWIRE branch with maximally 16 motor starters. A 6-core cable is used for power

supply and data transmission. The correspondent motor starters form up a line toplogy and

are thus connected to the BL20-E-1SWIRE.

Electronics and connection technology are integrated in the housing. A base module is not

needed. The module can be combined with

other electronic modules within a station, provided the field wiring features tension spring

connections.

The BL20-E-1SWIRE operates totally independent from the higher level fieldbus, as the

BL20 gateways represent the fieldbus connection.
