10. Digital output
The device has an electrically isolated digital
output, which outputs the active energy, reactive
energy or apparent energy obtained as an S0
interface.
10.1 Pulse output function
After reaching a specific, adjustable amount of
energy, the device sends a pulse of a defined
length to the output. To use the digital output
(pulse output), configure
·the energy measured value (which is to be
output, parameter address 100),
·the pulse value (parameter address 102) and
·the pulse length (pulse pause, parameter
address 106).
10.2 Pulse output connection example
10.3 Pulse value (parameter address 102)
The pulse value specifies how much energy
(Wh or varh) a pulse should correspond to.
The pulse value is determined by the maximum
connected load and the maximum number of
pulses per hour.
·If the pulse value is specified with a positive
sign, pulses are only output if the measured
value also has a positive sign.
·If the pulse value is specified with a negative
sign, pulses are only output if the measured
value also has a negative sign.
Pulse value =
max. connected load
max. number of pulses/h
Pulses/Wh
NOTE
·Since the active energy counter works with
a non-return device, pulses are only output
during consumption of electrical energy.
·Since the reactive energy counter works with
a non-return device, pulses are only output
during an inductive load.
