Overview
Distributed command devices of the 3SB3 series can be quickly
connected to the AS-Interface using AS-Interface enclosures.
Using suitable components you can make your own enclosures
with integrated AS-Interface or flexibly modify existing enclo-
sures.
Installation of AS-Interface slaves
The following
slave types are available for connecting the command positions:
7 Slave in A/B technology with 4 inputs and 3 outputs
7 Slave with 4 inputs and 4 outputs
7 F slave with 2 safe inputs for EMERGENCY STOP
The following table shows the maximum number of equippable
slaves:
1) For metal enclosures with 4 command positions, only 1 x slave 4E/4A
or 4E/3A is possible.
Connection
One set of links is required in each case to connect a slave to
contact blocks, to lampholders and to the connection element.
The connection elements are mounted in the front-end cable
glands and are used for connection of the AS-Interface or for
bringing unused inputs or outputs out of the enclosure.
For connection to the AS-Interface bus there is a choice of the
following options:
7 Terminal for shaped AS-Interface cable. The cable is con-
tacted by the insulation piercing method and routed past
the enclosure on the outside (possible only with plastic enclo-
sure).
7 Cable gland for the shaped AS-Interface cable or round
cable. The cable is routed into the enclosure (preferable for
metal enclosure).
7 Connection using M12 plug.
If less than all inputs/outputs of the installed slaves in an enclo-
sure are used for connecting the command devices, free inputs
and outputs can be routed on request to the outside through an
M12 socket on the top or bottom side of the enclosure.
To supply inputs with power, the S+ connection of the slave must
be assigned to the socket, for outputs the OUT– connection
must be assigned.
Addressing is performed using the AS-Interface connections or
the integrated addressing socket. An external power supply is
not required.
