¾ESA EXP-2: expansion that allows to control a package type burner, able to activate the air valve or blower, check
the air pressure switch status and control the air damper during the prepurge and burner ignition phases. The EXP-2
expansion card can also be used only to control the air valve (for versions that are different from ESTRO-A).

EXP-3: expansion allowing to interface the flame control with the most common field bus. For detailed informa-
tion refer to specific data sheet E7015.

internal relay protection fuse that blows only in case of
malfunctioning
of the first. ESA ESTRO is supplied in a
robust case in thermoset material, predisposed for the
housing of the ignition transformer and for the outputs of
the various connecting cables with external users.
Expansion cards that allow further control of the burner
devices or specific serial communication can be applied
to all the versions. The installation of the expansion cards
precludes the possibility of mounting the ignition transfor-
mer inside the instrument.The available expansions are
indicated below:
