Brahma 24085281 SM191N.2 control box

Brahma SM191N.2  gas control units 24085281 are designed for efficient control of burners running on atmospheric gas, both with and without a fan in the combustion circuit, especially in conditions of intermittent operation. All devices in this series are equipped with non-volatile locking, providing an additional level of security. If there is a security lock, restarting is possible only when the system is manually unlocked.

The main features of this series include CE type certification in accordance with European gas Directives, compliance with EN298:2003 standard, flame detection based on the rectification (ionization) effect, two independent safety contacts, long service life, built-in manual release, built-in ignition device and auxiliary contact for low-power ignition or control of the main solenoid valve for pilot systems with interruptions. The devices also have various connection and locking options, which makes them versatile and flexible to install and use.

Construction

1. Plastic container: The device is equipped with a durable plastic container, which performs the function of protection against various malfunctions, such as shocks, unauthorized access, dust accumulation and environmental impact. This design ensures a long service life of the device and reduces the risk of damage.

2. Manufacturing technology: The use of a special manufacturing technology, including the assembly of four printed circuit boards in a “box” design, contributes to a significant reduction in the dimensions of the device. This allows efficient use of space and ensures the compactness of the device.

3. Varistor: The built-in varistor serves to protect the device from transient voltage that may occur in the electrical network. This prevents damage to the device and ensures stable operation in various mains voltage conditions.

4. Built-in fuse: The device is equipped with a built-in fuse that protects the internal relays from short circuit at the control outputs, such as solenoid valves, fan and signal box. It is important to note that this fuse is not available for replacement, therefore an external fast type fuse is provided, which is suitable for connected loads and does not exceed 3.15 A.

These design features provide reliable protection and stable operation of the Brahma SM191N.2 24085281 gas controller in various operating conditions, making it an efficient and durable burner control solution.
