Brahma Control box SM11PMIX 24019905

Microprocessor-based control box for automatic ignition control, flame monitoring, and safe operation of atmospheric gas burners with intermittent operation, with or without a fan in the combustion circuit. It has a safety time of 5 seconds and reacts to flame loss in less than 1 second. The unit supports ionisation, UV, or IR flame detection methods and includes a manual reset lockout feature. It fully automates the combustion cycle: checking for absence of flame, pre-purge, ignition, continuous monitoring, and safe shutdown. The control box monitors pressure switches and the flame detector and connects via a specific base or plug pattern.

Control boxes of this type are selected by exact series and type designation, supply voltage, safety and pre-purge times, and the flame detection method (ionisation, UV, or IR). They use a specific base or plug pattern, and even within the same brand, control boxes are generally not interchangeable across different series. Before ordering, verify the original part number or exact specification against the burner documentation. On modern wall-hung boilers, an electronic PCB performs the same role but is matched to the boiler model, whereas this type of box is typically found on larger or standalone burners.
