LED display
The module has two yellow LED displays, which flash when an input is being closed.
When the input is open, a 5V power is measurable. The edge is being counted during the closing of the input. A
continuously closed input does not cause a modification of the counter readings.

Software / Control
The component is being read out per 1-Wire commands for the DS2423 module. Details for a power counter can
be taken from a sample program in the download area of the shop.

Function S0 Interface
The S0 interface is suitable for all types of energy meters and wind turbines and should not be confused with an
S0 interface of ISDN telephone systems.
An S0 interface works according to the principle that e.g. an energy meter provides a defined number of pulses
for a certain amount of energy. Once the number of pulses related to the amount of energy, e.g. an electricity
meter, is known, the current electricity consumption can be calculated very easily.

How is an electricity consumption recorded / calculated?
Example: An electricity meter emits 1000 pulses per kW/h. One pulse corresponds to an output of 1W/h. If the
counted impulses are read in every 3 minutes and the delta to the last readout cycle was formed, we know how
