## Long description

ZAMEL WZM-01/SOS (SOS-01) is a twilight sensor switch for automatic control of lighting circuits. Designed to operate from a 230 V AC supply, the device switches resistive and inductive loads up to 16 A and features an adjustable light sensitivity range from 0 to 200 lux. An external probe allows flexible mounting away from the module body so the light sensor can be positioned for accurate ambient measurement in street, garden, façade or corridor lighting applications.
Advantages
The twilight switch provides reliable automatic switching based on measured ambient illuminance and allows fine adjustment across the 0–200 lx range for precise activation thresholds. The external probe increases installation flexibility and helps avoid incorrect switching due to heat or artificial light near the control unit. Rated for 16 A at 230 V, the device supports a variety of lighting loads and simplifies automation without requiring complex programming.
Suitable for
 Automatic street and pathway lighting
 Garden and landscape illumination
 Façade and architectural lighting control
 Corridor, stairwell and outdoor entrance lighting
Key specifications
 Supply voltage: 230 V AC
 Switching capacity: up to 16 A
 Sensitivity range: 0–200 lux (adjustable)
 External light probe for remote sensing
 Designed for mounting in electrical enclosures or on DIN rail-compatible installations
How to use
Install the main unit in an appropriate electrical enclosure following local wiring standards and connect the external probe to the dedicated input. Position the probe in a location representative of the area to be controlled, away from direct artificial light sources and heat-emitting equipment. Set the sensitivity dial to the required lux threshold so the lighting switches on and off at the desired ambient illumination. Verify correct operation by observing switching at dusk and dawn and make minor sensitivity adjustments if needed.
Usage recommendations
For consistent performance, mount the external probe where it measures true ambient light (avoiding nearby lamps, reflective surfaces or local heat sources). Periodically check the probe for dirt or obstructions and clean as necessary. Ensure wiring and load connections comply with local electrical regulations and do not exceed the specified 16 A switching capacity.
