1 - FONCTIONNAL
- This unit is mainly an interface between external signals
and low power electronics.
- It is composed by :
• The adaptation three phases transformer between
input voltage and measurement circuits.
• The AC/DC converter to give an image voltage of the
mains voltage.
• The interface input relays between command / control
terminals and internal circuits.
• The interface between 64pts BUS and the analogic
input / output terminals.
2 - ADJUSTMENTS
- P01 : Ur setting for mains nominal voltage. (10Vdc for
nominal value)
3 - INPUT / OUTPUT
