Main technical specifications Parameter Value Model Brahma VM44G Part numbers 37200760, 246.124.255 Supply voltage 220–240 V, 50/60 Hz Power consumption 30 VA Burner type Forced draught (with fan), single-stage or two-stage Combustion method Forced draught burners Fuel type Gas Operating mode Intermittent Pre-purge time (Tv) 30 seconds Safety time (Ts) 2 seconds Flame monitoring Ionization electrode Operating temperature from -10°C to +60°C Protection class IP40 Weight ~0.4 kg Service life > 250,000 cycles Key functions and features Ionization flame monitoring – reliable and instantaneous flame detection. Non-volatile lockout – in an abnormal situation, the device locks and retains this state even when power is disconnected, preventing spontaneous start-up. Manual reset – restart after a lockout is only possible via the button on the housing, which is a key safety measure. Air damper control – support for various types of servos for precise flame modulation. Two independent safety contacts – redundant gas valve control circuits for maximum reliability. Diagnostics and indication – possibility to connect a signal lamp for lockout indication and data transmission about the operating cycle via a special cable. High reliability – service life of electronic components over 250,000 cycles.
