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.
