Specifications

Notes

Safety InformationAdjacent devices of the same type are devices of the same design (series) that are arranged next to one another on the DIN-rail with the same orientation. An end stop (249-116) must be fitted to devices of other types for compliance with the reinforced insulation requirements.
NoteTo protect the relay coils and contacts, inductive loads must be dampened with an effective protection circuit.
