Brahma 37200755 VM44G control box

Brahma VM44G, art. 37200755 is a microprocessor controller designed for automatic ignition control, flame monitoring and safe operation of forced draft gas burners in intermittent (cyclic) mode. The device complies with European standard EN 298, ensuring stable operation and a high level of safety for low and medium power burners. Main technical characteristics: Parameter Value Model Brahma VM44G Part numbers 37200755, 246.124.259 Supply voltage 220–240 V, 50/60 Hz Power consumption 30 VA Burner type Forced draft (with fan), single-stage or two-stage Combustion method Forced draft burners Fuel type Gas Operating mode Intermittent Pre-purge time (Tv) 30 seconds Safety time (Ts) 2 seconds Flame control 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 control – reliable and instant flame detection. Non-volatile lockout – in case of fault, the device locks and retains the state even after power failure. Manual reset – restart after lockout is possible only by button on the housing, preventing automatic burner restart. Air damper control – support for various types of servos for precise modulation. Two independent safety contacts – redundancy of gas valve control circuits. Diagnostics and indication – possibility to connect a lockout indicator lamp and transmit operating cycle data via a special cable. High reliability – service life over 250,000 cycles. Compact design – surface mount technology reduced dimensions. Built-in protection – varistor against voltage surges and fuse
