Description
The Brahma DMN31PR 37565050 combustion manager is used to equip gas burners with an intermittent cycle. The built-in microprocessor ensures a precise sequence of commands and safe operation of the combustion system.
More about Brahma DMN31
The Brahma burner automatic is equipped with an ignition transformer to generate a high-voltage discharge that ignites the fuel. The built-in EMC filter minimizes electromagnetic interference.
The automation provides safe ignition and control of all combustion stages. An ionization electrode is used to monitor the flame. The combustion manager instantly reacts to flame loss/absence, interrupts the gas supply and activates lock-out mode. A manual reset is used for exit.
The microprocessor is protected by a compact housing made of heat-resistant, impact-resistant plastic. The necessary level of protection against electric shock, dust and moisture ingress is achieved during installation.
Main parameters and features:
- version for fan burners with direct ignition;
