Specification
Notes
| Safety Information | A separator plate (e.g., 209-191) must be used for voltages exceeding 250 V between adjacent relay modules and to comply with reinforced insulation requirements. |
|---|---|
| Note | Reinforced insulation between coil and contacts, To protect the relay coils and contacts, inductive loads must be dampened with an effective protection circuit. |
