Digital outputs

Functions
The following functions can be assigned to both digital outputs:
● Energy pulse output, programmable for active or reactive energy
● Switching output for remote control via the RS 485 interface
Energy pulse output
The digital output supplies a number of pulses proportional to one of the following energies:
● Active energy import
● Active energy export
● Reactive energy import
● Reactive energy export
