Brahma 24284621 SM192N.2 control box

Brahma SM192N.2 is a microprocessor-based controller ("burner management system") designed for automatic ignition control, flame monitoring, and safe operation of two-stage atmospheric gas burners with an intermittent cycle. The device is suitable for both natural draft (without fan) and forced draft (with fan in the combustion circuit) burners. Model SM192N.2 (art. 24284621) is specifically designed for equipment operating in two-stage mode (partial load / full load), which significantly saves fuel and reduces the number of starts/stops. Applications include: two-stage gas heating and combination boilers (domestic and industrial); air heaters, hot air generators (Master, OKLIMA, etc.); air heaters, infrared heaters; water heaters, process furnaces, drying chambers; Riello, Baltur, Weishaupt, Lamborghini two-stage burners. Main 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 automated combustion cycle: The unit independently performs the complete 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 upon flame loss is less than 1 second, meeting EN 298 requirements. High safety class: Manual reset lockout – in any abnormal situation (no flame...
