Caja de control Brahma 37201251 MPI22

Brahma MPI22 (art. 37201251) burner management control unit is a microprocessor controller for automatic control of forced draught burners operating in intermittent mode. The device provides a complete cycle: pre-purge, ignition, flame monitoring and safety lockout in case of faults. The MPI22 model is suitable for gas, oil and dual-fuel burners of multi-stage or progressive type. Thanks to its compact housing and high reliability, the controller is widely used in both domestic and industrial heat generation systems. Main technical specifications Parameter Value Supply voltage 230 V (+10%/-15%), 50/60 Hz Power consumption 7.5 VA (start) / 9 VA (run) Flame control Ionization or UV sensor UV1 Burner type Forced draught, multi-stage, progressive Fuel type Gas, oil, dual-fuel Operating mode Intermittent Pre-purge time (Tv) 20 seconds Safety time (Ts) 3 seconds Operating temperature from -20°C to +60°C Protection class IP40 Valve leak test Yes (activated on request) Dimensions (H×W×D) 10.3 × 10.3 × 9.1 cm Weight 0.95 kg Key features Non-volatile lockout.
