outs 0-10v

[<P@vel>]

Hello!

I have system ProfiLux 4
And I installed on it the outs 0-10v for temperature, pH, Redox and Conductivity.
What range temperature, pH, Redox and Conductivity is corresponding 0-10v?

Best regards,
Pavel

Hi,
You could select the set point (nominal value) and range (hysteresis) you like for each of the sensors. What are you trying to control with each of those?

I want to use these information in my home automation. So I need know how and where to set these parameters for ProfiLux 4.
Maybe I don't understand, but I can not find where to set it up for 0-10. I need to have these information for my smart house visualisation.
Thank you for respond in advance.

I don’t know if that is possible. As far as I know this is more specialized for aquariums. If you just want to view readings from these sensors, you may be limited to using the app, desktop software, and through your ProFilux’s IP address.

I will be following this thread as I would like to know how this turns out.

While you are working on API, maybe you will answer on that topic too, please. So I can have these parameters in my home autoamtion visualisation now.

You can use the 1-10V output to determine the actual value based on the nominal value.

To do so, note the sign (this is the relay signal)
High = negative control deviation
Low = positive system deviation

Attention: Relay signal is not a push-pull signal, but open collector (OC), which is done in the ULN2803:

OC means, it is only actively pulled against GND, if you want to have positive signals you have to put output with pullup to positive potential.
