صندوق التحكم في نظام «Brahma» 24081981 SM191.1

Brahma SM191.1 is a microprocessor controller ("flame safeguard") designed for automation of ignition, flame monitoring and safe operation of atmospheric gas burners with flame modulation. The device is suitable for burners both with natural draft (without fan) and forced air supply, especially under variable intensity operation. Application area includes: gas heating and combined boilers (domestic and industrial); Master heat guns (BV70, BV110, BV170, BV290; B230, B360), OKLIMA; water heaters, air heaters, furnaces; Riello, Weishaupt, Giersch, Viessmann, Lamborghini burners. Model SM191.1 part no. 24081981 is a direct alternative for control units in equipment of the mentioned brands. Main functions and features Full automation of the combustion cycle: the controller independently manages the complete cycle: check for absence of false flame → pre-purge → ignition (built-in high-voltage coil) → 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 high safety standards. High safety class: Manual reset lockout – upon alarm activation, restart is possible only after eliminating the fault and pressing the Reset button. Non-volatile lockout – even after a brief power interruption, the unit remains locked, preventing spontaneous start-up. Surge protection – built-in varistor and fuse protect the electronics. High service life: the controller is rated for more than 250,000 on-off cycles. Durable housing made of heat-resistant plastic
