• each group of two inputs at 24 Vac/Vdc or 230 Vac has the same common pole, and thus works both at 24Vac/Vdc or 230Vac;

These are divided into 3 groups with two common pole terminals to simplify assembly of the common pole. Pay attention to the current
running through the common terminals, in that this must not exceed the rated current of a single terminal.
The relays are divided in groups, depending on the insulating distance.
Inside one group, the relays have single insulation among them and thus they must support the same voltage (generally 24Vac or
110÷230Vac). Among the groups there is double insulation and so the groups may be at different voltage.
