Brahma 24283331 SM192N.2 control box

Brahma SM192N.2 is a microprocessor controller (burner management system) designed for automatic ignition control, flame monitoring, and safe operation of atmospheric gas burners of two-stage type with intermittent cycle. The device is suitable for burners both with natural draft (without fan) and with forced air supply (with fan in the combustion circuit). Model SM192N.2 (art. 24283331) is specially designed for equipment operating in two-stage mode (partial load / full load), which significantly saves fuel and reduces the number of starts/stops. Application area includes: two-stage gas heating and combined boilers (domestic and industrial); air heaters, hot air generators (Master, OKLIMA, etc.); air heaters, infrared heaters; water heaters, process furnaces, drying chambers; burners Riello, Baltur, Weishaupt, Lamborghini in two-stage version. Key functions and features: Two-stage burner control: The controller provides sequential start of the first and second power stages, optimizing fuel consumption and ensuring smooth thermal power regulation. Fully automatic combustion cycle: The unit independently performs the full cycle: check for absence of false flame → pre-purge → ignition on first stage → ramp to full power (if needed) → combustion monitoring → safe shutdown upon flame loss. Ionization flame detection: Flame detection via ionization electrode (rectification effect). Reaction time to flame loss is less than 1 second, meeting EN 298 requirements. High safety class: Manual reset lockout – in any abnormal situation (no flame).
