Fieldbus Connection
The fieldbus connection for DeviceNet
TM
is made via Series 231 5-pin plug
connector from the
MULTI CONNECTION SYSTEM (MCS)
. A connector
(OpenStyle) is the counterpart. The 231-305/010-000/050-000 connector is
included.

according to DeviceNet

specification, identical to the conductors of the

cable
To connect small conductor cross-sections, an insulation stop of series 231-670
(white), 231-671 (light gray) or 231-672 (dark gray) should be used due to their
flexibility. The insulating stop prevents the conductor from deforming when
pushed against the conductor stop. As a result, the conductor insulation may be
clamped, causing intermittent contact or no contact at all. The marking of the
connector, as well as housing parts, test plugs with cable and male connectors for
cable extensions are available.
The connection point is lowered for mounting into an 80 mm-high switchgear
cabinet after connector attachment.
DC/DC converters and optocouplers in the fieldbus interface electrically isolate
the fieldbus system and the electronics.
