Separate circuits Interlinking blocks with a 5−pin plug enable separate circuits
to be created for supplying load voltage to the outputs/
valves and for supplying operating voltage to the electronics/
sensors. Fig.3/3 provides an overview.

Fig.3/3: Basic representation of the power supply concept for interlinking blocks with
5−pin alternative connections (7/8", push−pull)
The pin allocation for all alternative connections is described
in Tab.3/4 and in the package insert for the interlinking
blocks with supply.
