Classification according to ZVEI, CB24I
The following tables describe the classes and specific values of the product interface and
the classes of interfaces compatible with it. The classification is described in the ZVEI posi-
tion paper "Classification of Binary 24 V Interfaces - Functional Safety aspects covered by
dynamic testing".
