SUL 289 h analogue time switch, 1-channel 2890008

Analogue time switch with power reserve for daily or weekly programmes.

This time switch combines mechanical operation with quartz-accurate control and is suitable for simple automation tasks with flexible time intervals. Programming is carried out using tappets on a rotating dial in either daily or weekly mode, with switching times from 20 minutes for days and 2 hours for weeks, and optional 5‑ or 30‑minute steps. The NiMH-based power reserve maintains the time and programme until the supply voltage is restored. Manual summer/winter time correction and bidirectional time adjustment make seasonal changes straightforward, while switching preselection, an ON/OFF switch and clear status indication keep you flexible in operation.

For anyone who wants to combine analogue control with precise timing.
