Brahma 24080001 SM191N.1 control box

Brahma SM191N.1 is a new generation microprocessor controller ("flame safeguard") designed for automatic ignition control, flame monitoring and safe operation of atmospheric gas burners with intermittent cycle. The device is suitable for burners both with natural draft (without fan) and forced air supply (with fan in the combustion circuit). Model SM191N.1 (part no. 24080001) features an increased pre-purge time of 20 seconds (as well as a wait time of 20 seconds), making it an ideal choice for equipment requiring prolonged combustion chamber purging before ignition. Application area includes: gas heating and combined boilers (domestic and industrial); Master heat guns (BV, B series), OKLIMA and other air heaters; industrial air heaters, drying chambers; Riello, Baltur, Weishaupt, Lamborghini burners with atmospheric combustion. Model 24080001 is a direct replacement for control units on equipment requiring parameters tv=20 s / ts=10 s / tw=20 s. Main functions and features Full automation of the combustion cycle: the controller independently manages the sequence: check for absence of false flame → pre-purge (20 s) → ignition (built-in transformer) → combustion monitoring → safe shutdown upon flame loss. Ionization flame control: 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, ionization circuit break, ignition failure) the unit goes into safety lockout. Restart is possible only after eliminating the
