Turn-off time
●
Pulse length:
Time for which the signal at the binary digital output is at "high". The minimum pulse
length is 30 ms and the maximum 500 ms.
●
Turn-off time:
Time for which the signal at the digital output is at "low"
. The turn-off time depends on the
measured energy, for example, and can be days or months. The minimum turn-off time is
30 ms.
●
Minimum turn-off time:
The minimum turn-off time is specified by the programmed pulse length.
Digital input
The following functions can be assigned to the digital input:
●
Tariff switching for two-tariff active and reactive energy counters.
●
Synchronization of the measuring 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 (S0 interface). Data is transferred
with the help of weighted pulses, e.g., a parameterizable number of pulses is transferred
for each kWh.
A maximum voltage of 24 V can be applied to the digital input. Higher voltages require an
external voltage divider.
