Brahma 18049105 GR2 control box

Brahma GR2 18049105 gas control unit is designed to automate the start and control of all functions of liquid fuel burners with air supply to the furnace. Brahma GR2 18049105 relay provides continuous monitoring of the flame gorenje, disabling the safe shutdown of fuel supply in case of failures. The exit from the lock state is carried out easily by pressing the reset button or via a remote device, which ensures ease of operation and reliability of operation.

Construction:

1. Unique design: The use of surface-mounted components reduces the overall dimensions of the control panel.

2. Plastic housing: Provides protection against damage such as collisions, careless opening, dust ingress, as well as contact with the external environment, providing additional durability and safety of the device.

3. Varistor: The inclusion of a varistor in the design protects the control system from sudden voltage surges in the electrical network, ensuring stable and safe operation of the control unit.

4. Built-in fuse: Provides additional protection for the internal relays of the control unit in the event of a short circuit at the outputs, such as valves, ignition transformer, motor and lock signal.

These security measures contribute to:

– Reliable and long-term operation of the control system.

– Stability in various operating conditions.
