The 489 has four analog output channels (4 to 20 mA or 0 to 1 mA as ordered). Each
channel may be individually configured to represent a number of different measured
parameters as shown in the table below. The minimum value programmed represents the
4 mA output. The maximum value programmed represents the 20 mA output. All four of
the outputs are updated once every 50 ms. Each parameter may only be used once.
The analog output parameter may be chosen as Real Power (MW) for a 4 to 20 mA output.
If rated power is 100 MW, the minimum is set for 0.00 × Rated, and the maximum is set for
1.00 × Rated, the analog output channel will output 4 mA when the real power
