With option Bushing input: ”0...20mA AC Bush. In.“ or “0...100V AC Bush. In.“
With option Current input (External Sensors): “0...20mA anal In“ or “4...20mA anal. In“
For the next four inputs (Free analog #7 to Free analog #10), according to options purchased, the
following must be chosen:
With option Current input (External Sensors): “0...20mA anal In“ or “4...20mA anal. In“
For the next four inputs (Free virtual #11 to Free virtual #14), these four inputs are virtual sensors
and in any case have to be consider as external sensors or bushing sensors. It is used for calcula-
tion of Hot Spot Temperature, Aging Rate and Loss of Life
