Scatola di comando Brahma 37172414 SM11FR

Brahma SM11FR combustion control unit is a microprocessor controller ("flame safeguard") designed for automatic control of the ignition process, flame monitoring and safe operation of atmospheric gas burners with forced air supply (with fan in the combustion circuit). The model with the "R" index in the name (SM11FR) may have additional features such as an extended operating temperature range or improved noise immunity, but the main parameters correspond to the SM11F line. The device operates in intermittent mode and is suitable for a wide range of heat generating equipment: gas heating and combination boilers (domestic and industrial); air heaters, hot air generators; air heaters, infrared heaters; water heaters, furnaces, drying chambers; equipment with atmospheric burners of brands Riello, Baltur, Lamborghini, Weishaupt, Master, Oklima and others. Main functions and features: Full automation of the combustion cycle: the unit independently performs the sequence: check for absence of false flame → pre-purge (tv/tp) → ignition → combustion monitoring → safe shutdown upon flame loss. Ionization flame control: flame detection is carried out via an ionization electrode (rectification effect). Reaction time upon flame loss is less than 1 second, meeting high safety standards. High safety class: in any abnormal situation (no flame, ionization circuit break, ignition failure), the unit goes into emergency lockout with manual reset (Reset button). This prevents spontaneous restart and complies with EN 298 requirements. Built-in ignition transformer: the device is equipped with a built-in high-voltage coil, simplifying installation
