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 capabilities
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. Wiring complexity is reduced as the result. The
two-wire bus cable is fixed to the screw terminals in the connec-
tion element. Up to three 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.
Communication using a mobile phone
GSM radio elements are available for the 8WD44 series. They
can send error signals without delay to a mobile phone, e.g. as
an SMS or call. The device can be set to the GSM frequencies
customary in the EU and North America.
The radio elements are not allowed to be used in safety-relevant
applications.
Connection
The signaling elements are wired up using the screw terminals
in the connection element, screw terminals on the 8WD42 and
spring-loaded terminals on the 8WD44.
Cable outlet
The connecting cables can be guided either downwards or
sideways 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 for 8WD44
The two-wire bus cable is fixed to the screw terminals in the
connection element. The adapter element must be the first mod-
ule to be positioned on the connection element. A maximum of
4 signaling elements can then be mounted on it.
A/B technology enables the connection of up to 62 slaves on one
AS-Interface system. The addressing socket provides user-
friendly parameterization of the AS-Interface elements.
Connection to AS-Interface for 8WD42
The two-wire bus cable is fixed to the screw terminals in the
connection element. The adapter element must be the first mod-
ule to be positioned on the connection element. A maximum of
4 signaling elements can then be mounted on it.
The 8WD4228-0BB connection element for AS-Interface is a
standard slave.
