Brahma 24080056 SM11 control box

The Brahma SM11 24080056 control and regulation units are designed to control gas atmospheric burners with a fan in the combustion circuit or work without it in non-constant operation conditions.

Application

• Steam convectors;

• Heating boilers;

• Warm air generators;

• Radiator tubular heaters;

• Water heaters and other gas installations with an atmospheric burner.

Features

1. EU certification: Gas appliances are certified in accordance with Directive 90/396 on gas appliances and the corresponding amendment to Directive 93/68, confirming their compliance with the standards and requirements of the European Union.

2. Compliance with standards: They comply with the EN 298 standard, which guarantees their compliance with European standards for automatic programming systems and flame control of gas burners.

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

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

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

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

7. 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.
