Brahma 18049000 GR1 control box

Brahma GR1 18049000 gas controllers are specially designed for oil burners designed for non-permanent operation. They are suitable for monoblock oil burners, electric washing machines, warm air generators, steam boilers and furnaces. These Brahma GR1 18048700  automatic gas firing devices have technical and design characteristics that allow automating various devices with oil burners, both for domestic and industrial purposes. Thanks to these features, they provide efficient and reliable control of the oil combustion process in the burner, which makes them suitable for a wide range of applications where automation of oil burners in variable operating conditions is required.

Features

Features of Brahma GR1 18049000 burner controllers:

• Designed for non-permanent work.

• Operate at a fuel consumption of less than 30 kg/h (TSMAX = 10 s) or a fuel consumption of 30 to 100 kg/h (TVmin = 15 s and TSMAX = 5 s).

• Comply with DIN EN 13842:2004-10 standard for warm air generators (WLE) in versions with TV = 20 s and TS = 5 s.

• Have two independent safety contacts for controlling the oil valve.

• The service life of electrical equipment at maximum load exceeds 250,000 operations.

• Single flame mode is supported.

• It is possible to install a preheater.

• There is a built-in reset function.

• The possibility of an external remote reset is provided.

• Flame sensors FC11/, FC13/, FC14/, FC14L/, FT11/, FT13/ are supported.

These characteristics make the Brahma GR1 18049000 boiler controllers versatile and suitable for various applications where efficient and reliable control of oil burners in variable operating conditions is necessary. Compliance with standards, as well as the addition of additional functions, such as a preheater and an external remote reset, expand their functionality, meeting modern safety and efficiency requirements.

Construction

The special design and use of components installed on the surface make it possible to reduce the overall dimensions. The case, made of plastic, protects the control panel from possible damage as a result of collisions, careless opening, dust ingress and contact with the external environment. The varistor protects the control system from voltage surges in the electrical network. The built-in fuse protects the internal relays of the control unit in case of a short circuit at the outputs (valves, ignition transformer, engine and lock signal).

Connection

To connect external components, the control unit can be equipped with an N-type connector equipped with a screw terminal block, which provides a simple and safe connection. It is recommended to use M4 type screws to attach the sockets. To attach the control element to the outlet, use the pin included in the control unit package.
