Initiator terminals/Actuator terminals
ZIK•ZAK -
System advantages
For process control automation in machin-
ery and plants, initiators (such as triggering
switches) and actuators (such as magnetic
valves) are important components. To
reduce the amount of wiring needed they
are grouped and wired together on the
machine.
The limited space available often makes it
difficult to install terminal enclosures. In
such situations, it is necessary to use the
smallest possible components since little
room is provided for wiring and mounting
of the enclosure. However, no compro-
mises are acceptable in terms of ease of
installation, accessibility and clarity of the
wiring.
The new ZIK ZAK initiator/actuator terminal
from our Z-Series, fulfills the demands for
compactness and intraconnection by
employing a novel modular construction.

Modular distributor Systems
The terminal needed to connect the initia-
tor/actuator consists of a base element
and clip-on distribution elements. The
base element contains only the connectors
for the signal line.
The +/- supply and ground could be linked
within the enclosure.
Marking systems
The use of coloured insulators (reddish-
brown, blue and green/yellow) generally
makes identification easy. The two marking
channels for the connectors and signal are
angled to improve legibility.
Modular distribution strip
A cross-connection has already been inte-
grated with a male connector on one side
and a female connector on the opposite
side. Joining the elements together auto-
matically links up the cross-connection for
power distribution.
There is no need for additional cross-con-
nectors. There is no time spent attaching
cross-connectors and, of course, no errors
can be made with cross-connection. The
user can determine the number of poles
for cross-connection.
