Brahma-24083301-SM191N.2-Steuergerät

Brahma SM191N.2 is a compact yet powerful microprocessor controller ("burner management system") that takes full control of a gas burner: from purging and ignition to continuous flame monitoring and emergency shutdown. It is designed specifically for atmospheric gas burners operating in intermittent mode — both with natural draft and forced air supply. Thanks to its technical characteristics, this controller is an ideal solution for a wide range of thermal equipment: Industrial and domestic heating boilers; Hot air generators and heat guns, especially popular Master models (BV70, BV110, BV170, BV290, B230, B360), OKLIMA; Infrared heaters and radiant tubes; Water heaters and process furnaces; Professional kitchen equipment. Main functions and features: Full automation of the combustion cycle: The controller independently manages the sequence: checking for false flame → pre-purge → ignition → combustion monitoring → safe shutdown upon flame loss. Ionization flame detection: Flame detection is performed via an ionization electrode (rectification effect). Reaction time upon flame loss is less than 1 second, meeting the highest safety standards. Enhanced safety: In any abnormal situation (flame loss, ionization circuit break, ignition failure), the unit goes into safety lockout. Restart is only possible manually after troubleshooting and pressing the Reset button on the housing. Two independent safety contacts connected in series on the gas valve output provide an additional level of redundancy for critical circuits. Built-in ignition transformer: The device is equipped with a built-in
