Description
Honeywell DKG972-N mod. 21 control box (SKU 0432021) is a microprocessor-based unit for two-stage atmospheric burners. Operating at 230 V with a consumption of 12 m3/h, it provides flame supervision via ionization current with a sensitivity of 0.7 µA in no-flame mode, a sensitivity to ambient light of 0.4 µA, and a maximum ionization current of 26 µA. The minimum required ionization current for flame level is 1 mkA. The unit includes a built-in display, LED indicators, error memory, flame relay output, and flame arrester. Its housing is made of fire-resistant plastic, rated IP40, and weighs 175 g. It complies with EN 298:2003 and EN 230:2005, classification ATLLXN, and functionally replaces the earlier DKG972 control box.
