Monobloc TBXs comprising only one element, which cannot be extended (IP20),

Sealed TBXs comprising only one element, which cannot be extended (IP65). They have 8 inputs, 8 outputs, 16 inputs or 16 outputs,

Modular TBXs assembled by the user by combining a communication module and a base unit, which constitutes a basic module (IP20).

This base can be extended by a second base, using a connection cable and equipped with a cap connected to the communication module.

This enables the number of TBX connection points to be doubled.

The modular structure and ability to mix modular TBXs means that they can be better adapted to the requirements of the cell.
