The 489 has four analog output channels (4 to 20 mA or 0 to 1 mA as ordered). Each channel may be individually config-
ured to represent a number of different measured parameters as shown in the table below. The minimum value pro-
grammed 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 measurement is 0 MW. When the real power measurement is 50 MW, the analog output channel will
output 12 mA. When the real power measurement is 100 MW, the analog output channel will output 20 mA.
