Specification
Notes
| Safety Information | Adjacent 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. |
|---|---|
| Note | Optocouplers and solid state relays are designed for use in signal processing networks that are not supplied directly by the low-voltage power supply network. |
