Notes

Safety information

A separator plate (e.g., 209-191) must be used for voltages greater than 250 V between adjacent relay modules and for compliance with the reinforced insulation requirements.

Note

Reinforced insulation between coil and contactsTo protect the relay coils and contacts, inductive loads must be dampened with an effective protection circuit.
