Note the continuous current from the same line. IF1 were assigned the hybrid distributor position the case with the remaining posi-

the machine vision module position IF2 was assigned the hybrid distributor. Both lines are crossed over the printed

A power supply line can not only consist machine vision modules, but can also extended with hybrid

can powered via the line.
Information:
Both distributor boxes must therefore supplied from single power supply source (they
must have the same reference potential)!
