MODULAR TWILIGHT SWITCH KEY TWO RANGES 230V/16A TYPE: WZM-02

Product Description

The twilight switch WZM-02 is used to control lighting devices and other energy receivers depending on luminous flux density. The system switches on the lighting at dusk and switches off at dawn. The device is equipped with two illuminuous flux density ranges where the switching on threshold can be adjusted by the user. The system has the continuous output (load) switch on function (ON) , connected
to output (load) relay terminals, and the automatic function (AUTO). External luminous flux density sensor SOH with a cable of 50 m maximum length enables the sensor to be put in a suitable place.
