Convert 0-10v output to digital output
Does anyone have any modules they use to convert your 0-10v output to a relay output?
I have used EASY IO FR-02 and they work but are expensive.
Others have recommended driving a 12vdc relay, this turns the light on the relay but doesn’t energise the coil.
The bms output is very low current so cannot drive low voltage delay coils.
I have also seen the use of voltage comparators, optocouplers etc
Any advice on reliable cheap solutions?
