Brahma 37112211 SM11F control box

Brahma SM11F 37112211 gas control units are designed for efficient control of atmospheric gas burners with a fan, regardless of the presence in the combustion circuit. It can be equipped with a non-volatile or volatile lock: in the first variant, restarting after an emergency lock requires manual intervention, in the second – restoring the controller is possible only through a break in the supply and restoration of power supply.

Combustion ionization units SM11F 37112211 find their application in various devices such as steam convectors, heating boilers, warm air generators, radiator tubular heaters and water heaters. Gorenje The flame detection mechanism uses the ionization property without having a protective resistance, which makes contact with the detection electrode unsafe.

Features

• Flame control: The flame is controlled based on the rectifying properties of the flame using ionization, which is one of the methods of flame detection in gas systems.

• Safety and reliability: The two-independent safety contacts after the gas valve provide an additional level of safety, especially in models with manual reset.

• Durability: Electrical equipment is highly reliable, having a claimed service life of more than 250,000 operations at maximum load, which emphasizes their durability.

• Ignition device: The built-in fully solid-state ignition device ensures high efficiency of the ignition process.

• Auxiliary contact: There is an auxiliary contact for low-power ignition or control of the main gas valve in intermittent power control systems. However, it should be borne in mind that this contact is not isolated from the main supply voltage by reinforced insulation and therefore is not suitable for controlling SELV circuits.

• These characteristics indicate a high level of safety, compliance with standards and reliability of gas appliances, which makes them suitable for various gas installations and control systems.
