Brahma 37201221 MPI22 control box

Brahma MPI22 burner controller (art. 37201221) is a microprocessor-based control unit designed to automate the ignition process and combustion control in forced draught combined burners operating in intermittent mode. The device provides a full control cycle: from pre-purge and ignition to continuous flame monitoring and safety lockout. This controller is a new solution that combines all typical burner control functions in one housing, which is a technical and economic advantage. The device is certified according to EU standards and is suitable for equipping both domestic and industrial heating systems. Key features: Comprehensive tightness check. An integrated gas valve tightness check program can be activated on request, increasing system safety. Non-volatile lockout and manual reset. In case of emergency shutdown, the system goes into a safe state; manual reset is required to restart. Flexible flame monitoring. Supports flame monitoring both via ionization electrode and using a UV sensor type UV1. Air damper control. Ability to control various types of air dampers allows flexible adjustment of the combustion process. Two independent safety contacts. The gas valve is controlled via two independent safety contacts, increasing system reliability. Protection against short circuit and voltage surges. Built-in varistor protects the device from voltage surges, and an internal fuse protects against short circuit on outputs. High service life. The service life of the electrical equipment is at least 250,000 operations at maximum load. Main technical specifications: Parameter
