Twilight switches switch electrical appliances on when it gets dark and off again when it gets light. Devices in this series have an external sensor. They can be installed in the distribution board and adjusted from there, regardless of the location of the lighting. The operating and control voltage of the devices is 230 V AC. The EDS 16 compares the current illuminance with the set switch-on threshold. If the illuminance reaches the desired switch-on threshold, a delay time starts. Once the delay time has expired the load relay of the twilight switch is switched on. If the switch-off threshold is reached due to increasing illuminance, the relay switches off again after the delay time has expired. The slow switching responses prevent unnecessary switch-on or dangerous switch-off when the brightness changes briefly (e.g. due to lightning and car headlights).

energy saving thanks to automatic lighting control, switch-on/switch-off delay mutes brief fluctuations in brightness, low internal consumption, easy mounting and adjustment , adjustable switch-on threshold of 2 to 1000 lux, switch-off threshold prescribed by internal factor 1.5, potential-free NO contact (16 A), switch-on/relay status indicated by LED , LF 1 light sensors for outdoor mounting (IP44), cable length to LF 1 up to 100 m , more than one twilight switch can use one LF 1.

Twilight switch: quick fastening to mounting rail, any installation position Light sensor LF 1: , Wall mounting, preferably facing north or east

Control of lighting for streets, buildings and industrial premises.

Depending on the order number, the twilight switch is supplied with or without a light sensor.
