Description
The Brahma NDM12 37520007 combustion manager is based on microprocessor technology for efficient control of atmospheric gas or oil burners in unstable operating conditions. The automation system includes an ignition transformer and an EMC filter to suppress electromagnetic interference.
More about Brahma NDM12
The Brahma NDM burner controller is responsible for the safety of ignition, monitoring and controlling all stages of combustion. Depending on the type of burner, an ionization electrode or an FD photodetector is used to monitor the flame. In the absence of a flame after the allotted time before ignition or disappearance during operation, the combustion manager immediately switches to lock-out mode, stopping fuel supply to the burner. A manual reset button is used to exit the protective shutdown state.
The microcontroller and electrical components are protected by a housing made of impact-resistant, heat-resistant plastic. Dust and moisture protection of the device is not provided. Safety is achieved by proper installation of the controller.
Main parameters and features:
- power supply from 220-240 V, 50/60 Hz network;
- intermittent cycle, controlled restart every 24 hours for self-test;
- safety time: 10 sec.;
- built-in transformer and EMC filter for interference suppression;
- small PCB size to minimize device dimensions;
- protection against undervoltage, shutdown when parameters in the network are less than 175V;
- flame control with ionization electrode or with FD sensor;
- indication of current states and malfunctions;
- varistor for protection against peak voltages in the network;
- manual lock-out release using a button on the housing;
- instant response to flame loss/absence (< 1 sec.);
- operating temperature range: -20...+70 °C;
- dust/moisture protection according to IP 00 standard (implemented during installation, from IP 20 and above);
- compact design, easy installation and connection;
- can be placed in any position.
Application
Brahma NDM burner controllers are used in atmospheric burners of heating boilers, steam boilers, hot air generators, water heaters, furnaces, IR heaters and other industrial equipment.
