Brahma 18047013 TGRD61 control box

Brahma TGRD61 18047013 control unit based on KOMPACT series microcontrollers are specially designed for efficient control of gas atmospheric burners – with or without a fan in the combustion circuit – as well as oil atmospheric burners in variable operating conditions. The KOMPACT range, including the TGRD type, provides ignition and flame control functionality, including a built-in high-efficiency electronic ignition transformer. The KOMPACT series TGRD type has been updated with additional options and flexibility provided by a unified microcontroller approach.

Main Features

1. Non-volatile or non-volatile blocking:

– In case of non-volatile blocking, restarting the controller is only possible by manually resetting the system.

   – In the case of an energy-dependent lock, the controller can be restarted only by interrupting the power supply and then restoring it, excluding switching the heating device.

2. A variety of applications:

   – Suitable for use in combined heating and steam boilers, hot air generators, radiation tube heaters, convector heaters with a fan, water heaters, washing machines, furnaces and monoblock burners.

3. Compliance with standards:

– The series comply with EN 525, EN 1020 and EN 1319 standards for hot air gas generators.

   – For hot air oil generators, compliance with DIN 4794 standard.

Constructive

The use of an innovative circuit and surface mounting of components allows you to significantly reduce the size of the Brahma TGRD61 18047013 controller circuit board. The plastic case and, if necessary, the lacquer coating on the printed circuit board provide protection of the controller from mechanical damage resulting from accidents, pollution, dust and environmental influences.

Additional security elements:

– The varistor serves as protection against peak voltage in the power grid, including atmospheric discharges, such as lightning strikes.

– An internal available fuse protects the controller relay in case of a short circuit at outputs such as valves, fans and lock signals.

– Built-in electromagnetic interference filter reduces electromagnetic interference generated by the ignition discharge.

– Installing the resistor in series to the lock output signal protects the device from possible errors in connecting the remote unlock contacts.

Functions
