applications that complies with the most
relevant international standards.
All the elements required for each
application have been integrated into a
and simple utilization. The low number of
components, thanks to the use of state-
of-the-art but mature technology, deliver
a very high reliability.
Hardware inputs and outputs have been
designed in a modular way that allow
easy migration from simple to more
complex applications.
The control functions include a full-
scheme virtual PLC with an optional
graphical display. The combination of
both elements provide total control for
a bay. This means real-time monitoring
of breakers and selector switches, open
and close commands supervised by the
programmable interlockings and metering
