Overview
Hybrid fieldbus connection with two HanBrid sockets
Control cabinet bushing with two M12 sockets
Hybrid fieldbus connections with HanBrid sockets designed as
cabinet bushings transmit data and energy from the control
cabinet (IP20) to the field (IP65). They are the interface for jointly
routing PROFIBUS DP and the auxiliary voltages into the hybrid
fieldbus cable.
On the cabinet bushings with two M12 sockets for the
PROFIBUS M12 connecting cables, the 24 V supply of the motor
starters is implemented via separate 7/8" connecting cables.
Passive and active hybrid fieldbus connections
The hybrid fieldbus connections are available in two versions
which differ in their functionality. These are:
•
The passive version
•
The active version with signal refresher function to consider-
ably increase the maximum PROFIBUS cable length
Connection methods
The field side is connected using HanBrid or M12 plug-in
connectors.
In the case of HanBrid, the following versions are available:
•
Socket/socket for infeeding into the field
•
Pin/socket for looping in the field
The M12 version is generally configured with socket/socket.
Following connections are available at the rear (cabinet side) in
the case of the passive glands:
•
Direct connection
•
Fast Connect connection
The active gland with refresher function has 9-pole Sub-D
sockets for the rear connection.
Auxiliary power infeed
The HanBrid plug-in design offers the possibility of infeeding or
looping through not only the Profibus signal but also 2 separate
auxiliary voltages of 24 V DC (switched/unswitched) into the
field. The terminal block with spring-type terminals at the rear
(cabinet side) of the hybrid fieldbus connection provides a
variety of interconnecting operations for these auxiliary voltages.
Passive hybrid fieldbus connections
•
Gland from the control cabinet (IP20) into the field (IP65)
•
HanBrid plug-in design socket/socket or pin/socket
•
Direct connection or Fast-Connect connection for PROFIBUS
at the rear
•
Terminal block with spring-type terminals (0.25 … 2.5 mm

) for
infeeding or looping through the auxiliary voltages
