Brahma CE31 30615506 relay – efficient control of gas burners with a fan, capable of operating independently of combustion in the circuit. They can have a non-volatile or volatile lock, with manual intervention to restart in case of an emergency lockout or automatic recovery through a power outage. CE31 30615506 are used in steam convectors, heating boilers, warm air generators, radiator tubular heaters and water heaters. Their flame detection mechanism uses ionization, but has no protective resistance, which makes contact with the detection electrode potentially dangerous.


• Electrical reset

• Double flame

• Atmospheric with a fan

• Complies with EN298:1993

• Complies with EN298:2003 (2)

• Flame control based on the flame rectifying property (ionization);

• Two independent safety contacts in series at the outlet of the gas valve (models with manual reset);

• Service life of electrical equipment at max. declared load > 250,000 operations;

• Built-in fully solid-state ignition device with high efficiency;

• EU certification type (CE PIN code 0694BR1154) in accordance with Directive 90/396 on gas appliances and the following amendment to Directive 93/68;

• In accordance with EN 298 (European standard for automatic programming and flame control systems for gas burners);

• Auxiliary contact for low-power ignition or control of the main gas valve in intermittent power control systems (this contact is not isolated from the main supply voltage by reinforced insulation, therefore the relay contact is not suitable for controlling SELV circuits

The CE31 30615506 gas burner control unit has a robust housing made of plastic and self-extinguishing material, providing reliable protection against mechanical damage, dust and dirt. This not only prolongs the service life of the device, but also reduces the risks associated with exposure from the external environment. Optimization of the dimensions of the printed circuit board using a module with electronic components on the surface led to a reduction in the size of the device and an increase in its efficiency.

The principle of operation

When turned on, the controller performs self-monitoring and checks of components, including a flame signal amplifier and an air pressure switch. In case of malfunction detection, the controller is locked, ensuring the safety of the system.
