Ex-Twilight switch
For the comfortable and automatic control of lighting in hazardous areas.
This screw-in twilight switch has been approved for direct installation in Ex-d and Ex-e enclosures.
The electronics and the light-sensitive sensor are encapsulated in a flameproof light alloy enclosure with a M32 x 1.5 threaded connection. The encapsulated connection cables are 500 mm long.
The photocell has an electronic circuit with a low power consumption of less than 1 W and a voltage range of 100 V AC to 260 V AC 50/60Hz and switches a rated current of 10 A or a max. power of up to 1800 VA.
The electronics switch on immediately if the light falls below the threshold values. However, there is a 2 to 5 second switching-off delay to avoid accidental switching due to light flashes.
