Everything you need can be found
here. It's in English, but I assume you should be able to find the same information in Portuguese. I think your local AB distributor is:
Ladder Automação Industrial
Av. Lemos Monteiro
415/417 – Bairro Olímpico
São Caetano do Sul, São Paulo, CEP 09540-500
Contatos: Carlos Soares Peixinho (11) 9131-1686 (Celular)
You might be able to contact them for more information in Portuguese.
(We have an exchange student living with us who is from São Paulo
