Brahma 18047002 TGRD63 control box

The Brahma TGRD63 18047002 burner controllers based on KOMPACT series microcontrollers are specially designed for controlling gas atmospheric burners (with or without a fan in the combustion circuit) or oil atmospheric burners in non-constant operation conditions. The KOMPACT series of the TGRD type was created due to the need for an ignition and flame control device with a built-in high-efficiency electronic ignition transformer (a function already available in the KOMPACT series of the TGR type) with all the options and flexibility offered by a single microcontroller technology. These systems are equipped with a non-volatile or energy-dependent lock, in the first case, restarting the controller from the protective lock state can only be performed by manually resetting the system, and in the second case, restarting the controller from the protective lock state can only be achieved by interrupting the power supply and its subsequent restoration (and not by switching the heating device).

Application

Brahma TGRD63 18047002 gas burner control box are suitable for:

– Combined, heating and steam boilers; – Hot air generators; – radiation tubular heaters;

– convector heater with fan;

– Water heater;

– washing machine;

– furnaces;

– Monoblock burners.

Brahma TGRD63 18047002 automatic gas firing device is suitable for use in gas hot air generators in accordance with EN 525, EN 1020 and EN 1319 standards or in oil hot air generators in accordance with Part 2 of DIN 4794 standard.

Constructive

The use of an innovative circuit and components for surface mounting made it possible to reduce the dimensions of the controller circuit board.

The plastic housing (and the lacquer coating on the printed circuit board, if required) protect the controller from mechanical damage caused by an accident, hardening, dust and contact with the external environment.

The varistor protects the controller from peak voltage in the power grid caused, for example, by atmospheric discharges, such as lightning strikes.

An internal available fuse protects the controller relay in the event of a short circuit at the outputs (valves, fan and lock signal).

The built-in electromagnetic interference filter reduces electromagnetic interference generated by the ignition discharge.

Finally, a resistor connected in series to the lock output signal can be installed to protect the device from possible inversions of the remote unlock contact connection.
