Application
8WD4 signaling columns are used in machines or in automatic
processes for monitoring complex procedures or as visual or
acoustic warning devices in emergency situations, e.g. for
displaying individual assembly stages.
Communication capability
Connection to AS-Interface
The 8WD4 signaling columns can be directly connected to the
AS-Interface bus system through an adapter element that can
be integrated in the column. Wiring outlay is reduced as the
result. The two-wire bus cable is fixed to the terminals in the
connection element. Up to four signaling elements can be
mounted on it using an adapter element.
A/B technology enables the connection of up to 62 slaves on one
AS-Interface system.
Connection
The signaling elements are wired up using the screw terminals
in the connection element, screw terminals on the 8WD42 and
screw or spring-type terminals on the 8WD44.
Cable outlet
The connecting cables can be guided either downwards or side-
ways through the cable gland using an adapter that can be
screwed under the foot. This makes wiring easier if there is no
access from below.
Connection to AS-Interface
8WD42
The two-wire bus cable is fixed to the screw terminals in the
connection element. The adapter element must be the first
module to be mounted on the connection element. A maximum
of four signaling elements can then be mounted on it.
The 8WD4228-0BB adapter element is a standard slave.
8WD44
The two-wire bus cable is fixed to the screw or spring-type ter-
minals in the connection element. The adapter element must be
the first module to be mounted on the connection element. The
signaling elements can then be mounted on it.
The 8WD4428-0BE adapter element is a standard slave.
A maximum of four signaling elements can be mounted on it.
The 8WD4428-0BD adapter element with A/B technology
enables the connection of up to 62 slaves on one AS-Interface
system. The addressing socket provides user-friendly parame-
terization of the AS-Interface elements. A maximum of three
signaling elements can be mounted on it.
