Driving a counter mechanism
The width of the energy pulses can be selected within a
range of 30 up to 250ms, but have to be adapted to the
external counter mechanism.
Electro mechanical meters
typically need a pulse width
of 50...100ms.
Electronic meters
are partly capable to detect pulses in
the kHz range. There are two types: NPN (active negative
edge) and PNP (active positive edge). For this device a
PNP is required. The pulse width has to be
≥
30ms (acc.
EN62053-31). The delay between two pulses has to be at
least the pulse width. The smaller the pulse width, the
higher the sensitivity to disturbances.
