Brahma Control box DMN31PR 37565050

Brahma 37565050 DMN31PR is a microprocessor-based control box or flame safeguard for gas burners. It is designed for two-stage, intermittent (cyclic) operation and supports direct or pilot ignition; this PR variant is specifically adapted for systems with a pilot burner. The unit provides flame monitoring, two independent safety contacts on the gas valve output, and a manual reset lockout feature. It requires an external ignition transformer (not included). It is OEM-equivalent for Riello, Baltur, Weishaupt, and Lamborghini burners.

Control boxes of this type are selected by the exact series and type designation, supply voltage, safety and pre-purge times, flame detection method (ionisation, UV, or IR), and the base or plug pattern. They are normally not interchangeable across series, even within the same brand; a mismatched safety time creates a safety hazard. For electronic PCB-type controls in modern boilers, replacement is matched to the specific boiler model. Always confirm that the part number corresponds exactly to the original control's series designation and electrical ratings before ordering.
