Electricity meter pulse reading

[v4v]

Hi, it is possible to read pulses from LE-02d MID electricity meter? (SW 1.49d | HW 3.8)

In datasheet I see: Connection voltage SO + SO- max. 30 V DC
And digital inputs are up to 20V. So I guess no. Maybe resistor voltage divider?

you can add a 510om resistor to the INPDx input and it should be ok

Pulse output SO + SO- open collector
so voltage and current is not important in this case, no?!
~open collector~ no voltage provided, voltage you must supply....
Hoped I'm not OFF-TOPIC...

So connect LK inpud directly to S0+, SO- and set in Lk inputs Pull-UP

A 510om resistor on the INPDx input should work.

Reading pulses from the LE-02d MID power meter is not a default function of this product. However, you can use a resistive voltage divider to reduce the magnitude of the input signal so that it matches the range of the meter.geometry dash unblocked
