Hi,
I am trying to isolate a 4-20ma signal coming from a UV lamp unit on a water supply to a logger. I have a 100R resistor across this 4-20 on logger side at the moment to convert for the logger input, but due to a malfunction on the UV unit which allowed 110 V ac to pass on UV 4-20 I want to install an isolator.
The UV 4-20 MA output only has a small DC voltage across it (13vdc) so I am assuming it is not loop powered and would require an isolator with a separate 24 vdc power supply, does this sound correct?
Thanks in advance.
