Analog outputs
The IS-NT has one analog output available. Default setting of this output is the value of actual generator
power in the range 0 to 20 mA.
Hint:
It is possible to configure any other value available in the configuration using GenConfig.
If the output range 4 to 20 mA is needed, the limits for analog output should be set according to an example
in the following table:
Requested power range Controller analog output setting
0 – 1000 kW Low limit: -250 kW
High limit: 1000 kW
Low – High kW Low limit: Low - (High – Low)/4 kW
High limit: High kW
This setting ensures that 0 kW (Low kW) will correspond to 4 mA.
