Digital inputs

The following functions can be assigned to the digital inputs:
● Tariff switching for two-tariff active and reactive energy counters
● Synchronization of the demand period by means of the synchronization pulse of a system
control center or other device
● Status monitoring: Acquisition of statuses and messages of connected signal encoders
● Energy pulse input for active or reactive energy pulses. Data is transferred with the help
of weighted pulses, e.g. a parameterizable number of pulses is transferred for each kWh.
