1 Introduction
Before you start assembling the module and before you take the device into operation, please read these
operating instructions carefully to the end, especially the section referring to the safety notes.
2 Product description
The Dual S0 counter module is designed for energy recording of two independent electricity, water and gas
meters or wind turbines. All S0 devices manufactured according to DIN 43864 can be equipped with an isolated
S0 interface can be connected. If in doubt, check the data sheet of your energy measuring device.
After applying the operating voltage, the Dual S0 counter module is ready for operation. The integrated
Counter modules count the input pulses continuously. The counter readings are transmitted via the 1-Wire
Network from the memory of the Dual S0 counter module. The current number of pulses per
Time unit can be calculated by delta formation. Typical readout intervals are in the range of
1 - 3 minutes for electricity or gas meter. The Dual S0 counter module can be set to "zero" by pressing the reset
button.
The Dual S0 counter module is supplied by a 12V DC voltage. The working voltage of the 1-Wire data line is
typically 5V.
After failure of the operating voltage, previously counted input pulses are permanently stored internally.
The Dual S0 counter module counts pulses which are generated by closing an input (falling edge).
One green LED is available for each counter input. The respective LED lights up when the input is closed. A
permanently closed input does not cause any further changes to the counter reading.

7 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.
8 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.
9 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

much energy was consumed in the last 3 minutes. In order to display the power consumption in kW/h, we have to
extrapolate the power consumption to one hour (60 minutes / 3 minutes = factor 20).
We calculate the delta for the current number of pulses from the last and current meter values that we read from
the S0 meter. With a delta of 25 pulses, these correspond to a power consumption of 25 watts in the last 3
minutes.
In 60 minutes, with constant power consumption, there is a consumption of: 25 x 20 = 500W/h
0,5KW/h Power consumption
Calculation
The evaluation cycle of the S0 pulses is 3 minutes.
Factor = 60 minutes / 3 minutes Evaluation cycle
Delta pulses = new pulses - old pulses
Power consumption (KW/h) = (delta * factor) / 1000

10 Data output 1-Wire Controller / 1-Wire Gateway
For the Dual S0 counter module the following data of the 32Bit counter values are output.
The 1-Wire interface of the Dual S0 counter module is controlled by standard commands for the DS2423 block
and the data is read out.
The power of electricity meters, gas or water consumption can be calculated using the continuous meter values
output. A wind sensor can also be evaluated.
Data output:
The data output for the Dual Counter is in the following data format.
1_OWD1_1|Counter value A => Controller no._One Module no._Data set|Counter value 32Bit
1_OWD1_2|Counter value B => Controller no._One Block no._Data set|Counter value 32Bit

16 Storage of counter values / Delete counter values
The counter reading of the Dual S0 counter module is stored permanently, even without power supply.
The counter reading can be set to 0 by pressing the reset button for approx. 3 seconds. In order to avoid an
accidental reset of the counter reading, the reset button is recessed on the top of the module. To operate the reset
button, you need a pointed object, such as a match or toothpick.

in any position. The device is intended for use in dry and dust-free rooms.
If condensation is formed, allow at least 2 hours for the unit to acclimatize.
The modules may only be put into operation under the supervision of a qualified electrician. Do not operate the
module in an environment in which flammable gases, vapors or dust are present or could be present.
18 Assembly
The installation site must be protected from moisture. The device may only be used in dry indoor areas. The device
is intended for installation inside a control cabinet as a stationary device.
