SUL 189 s analogue time switch, 1-channel 1890801

Analogue time switch with quartz-accurate power reserve.

This time switch combines a mechanical clock movement with quartz-controlled operation and designed for precise daily programs in 15-minute steps. The time is set manually using clock hands, allowing quick, simple adjustment on site, and seasonal changes between summer and winter time can be corrected directly on the clock mechanism.
In the event of a power failure, the integrated power reserve maintains all settings for up to 72 hours without data loss. The current switching status can be read at a glance via the indicator, while the permanent switch enables temporary manual override if required. For installation, you can choose between panel mounting and wall mounting, depending on the application.

For simple control tasks with consistent precision – even in the event of a power failure.
