The connection frame can take up to four connectors,
and four conductors can be connected to each connector.
“PUSH IN” technology allows for ne-wired conductors with
crimped wire-end ferrules or ultrasonically welded conduc-
tors, each with a maximum cross-section of 1.5mm², to be
inserted easily through the opening in the clamping terminal
without having to use tools. To insert ne-wired conductors
without wire-end ferrules, the pusher must be pressed in
with a screwdriver.
Connectors with four conductor connectors
The pushers are colour-coded for the following connections:
Grey Signal
Blue GND
Red 24VDC
Green Functional earth (FE)
Detailed descriptions of the individual module types are
available in Chapter6.
Cable protection
The modules listed in the following table do not have a fused
sensor/activator power supply. Here, all cables to the con-
nected sensors/actuators must be fused corresponding to
their conductor cross-sections (as per Standard EN60204-1,
section12).
Modules Order No.
