current to voltage converter v1.0

It looks like it would be a problem if I grounded the power supply as shown above…

Since there is no ‘isolation’ on the converter module.  

It also seems like it could be a problem if it is left floating like the datasheet shows…

Wouldn't it be better to swap the sensor and the converter in the circuit so that both the power supply and the arduino can use the same ground reference?

Hi,

what are resistors R2 and R5? Diodes D1, D2 and D3 are the same?

Thank you

Hi!

I have the same board an trying to get a stable voltage value with an input current range of 4mA-20mA. I'm using an LM2596 to get a more stable voltage to feed the SEN0262, but I'm unable to get a stable voltage value at all.

Any clue to where look to get usable values?

Thanks in advance,

Jordi

Sorry for the late reply.

Hope that helps.
