My customer has NetBotz 450 and wants to add a 3rd party water level sensor to it using the NetBotz 4-20 ma inputs. They would also be powering it with the NetBotz 24 VDC supply.

I've no documentation on wiring the current offering with a 3 wire config but if it's anything like the old 4-20 sensor pod, what you've drawn out looks similar to the 3 wire config in it's install sheet on page 4:
I'll check with engineering to see if this config has been tested directly on the current models.

Thanks Steve, Yup, I used the old 4-20mA pod manual as a reference for it, but wanted to double check since I couldn't find any current documentation either.
I also remember there being some caveats to trying to use it. IIRC, one of those was regarding using an external power supply, but this config should take care of that.
Thanks again for checking with engineering, let me know when you can.

I can say that I'd seen issues in the past with the pod and using an external power source and similarly, I didn't think it relevant since your drawing was using the local source but that was about the only caveat I thought of as well.
