values taking into consideration as nominal values of the secondary windings
1 Amp and 100 V. If the 5 Amp current inputs are connected applying the
nominal rated current, it will be shown 1 A.
Line description: “Channel descriptor”“Channel number “: “Values”
Channel descriptor: Analog input
Channel number: x, where x addresses the analog input channel.
Values: CT (1-5 A) → Rated secondary current related to the current
input.
CT (0,2 A) → Rated secondary current.
VT (100 V) → Rated secondary voltage (Volt).
Sensor → Voltage output of the sensor (Volt).

module
With sensor inputs, the displayed values are the voltages read by the analog
channels. For example, by using the voltage divider 10.000/1 applying 20 kV
on the sensor, the measurement will show 2 Volt. For the current sensor 80 A/
150 mV, applying 80 Amp on the sensor the measure will be 0.150 Volt.
