Telvent GIT, S.A.
Valgrande, 6
28108 Alcobendas, Madrid
Spain

Ladies and Gentlemen:

      We are familiar with the proceedings taken and proposed to be taken by
Telvent GIT, S.A., a sociedad anonima organized under the laws of the Kingdom of
Spain (the "Company"), in connection with the registration under the Securities
Act of 1933, as amended (the "Act"), of 10,005,000 Ordinary Shares (the
"Shares"). As your counsel, we have collaborated in the preparation of the
Registration Statement on Form F-1 (the "Registration Statement") to be filed by
you with the Securities and Exchange Commission as of the date hereof to effect
the registration pursuant to the Act of the Shares.

      In this connection, we have examined such Company records, certificates
and all other documents, and have made such examination of law, which we deem
necessary to render the opinions set forth below. Each capitalized term used
herein, unless otherwise defined herein, has the meaning ascribed to it in the
Registration Statement. Attorneys involved in the preparation of this opinion
are admitted to practice law only in the Kingdom of Spain and the State of New
York and we express no opinion herein concerning any law other than the federal
laws of the United States of America and the Kingdom of Spain.

      Based upon and subject to the foregoing, we are of the opinion that, when
the Registration Statement has become effective and the capital increase
associated with the issuance of the Shares has been registered with the
Mercantile Registry of Madrid, the Shares, when issued and paid for as set forth
in the Prospectus constituting a part of the Registration Statement, will have
been legally issued by the Company and will be fully paid and nonassessable.

      The opinions set forth herein are rendered as of the date hereof, and we
assume no obligation to update such opinions to reflect any facts or
circumstances which hereafter may come to our attention or any changes of law
which hereafter may occur.

      We consent to the reference to our Firm wherever appearing in the
Registration Statement and to the inclusion of this opinion as an exhibit to the
Registration Statement. In giving such consent, we do not admit hereby that we
come within the category of persons whose consent is required under Section 7 of
the Act or the rules and regulations promulgated thereunder.

                                      Very truly yours,

                                      /s/ Squire, Sanders & Dempsey L.L.P.

                                      SQUIRE,  SANDERS & DEMPSEY L.L.P.
