Si (if) is a type of conjunction which can introduce conditional sentences, i.e sentences where there is a condition for the main clause to actually happen. The higher or lower possibility of the main clause fullfilling will depend on the tenses used.

There are three types of conditional clauses with si (if):

Type 1:

Si +El Presente + El Presente/El Futuro Simple/ El Imperativo

Type 2:

Si + El Pretérito Imperfecto Subjuntivo + El Condicional Simple

Type 3:

Si + El Presente + El Pretérito Pluscuamperfecto de Subjuntivo
Note there may be different combinations of tenses but these are what are considered the core conditional sentences in Spanish.
