Connecting the data outputs
S0-Interface
The consumption data measured by the econ sens+ is outputted via the pulse outputs Imp+ and Imp-
(open-collector NPN outputs) as a pulse sequence. Each output pulse is 50 ms long and corresponds
to a defined amount of energy in Wh. This can be configured via the web interface. (For details see
“Web Interface” chapter). The default value for this pulse weighting is 10 Wh/pulse, which corresponds
to an output of 100 pulses/kWh.
The pulse outputs are used for the automated capture of the energy consumption values by means of
a data logger, e.g. the Econ Unit. Fig. 11 shows the layout of the pulse interface.
The distance between the data logger and the econ sens + may be amount to max. 50 meter. When
connecting a cable, a shielded cable is recommended *, as Belden YE00820. For shorter distances an
unshielded cable can be used.
* A shielded cable should come in all applications where massive electromagnetic disturbances from the environment is
expected.
