Item description

Note:

Reinforced insulation between coil and contacts

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.

To protect the relay coils and contacts, inductive loads must be dampened with an effective protection circuit.
