PROC:  Siemens Hydroranger problem
------------------------------------------------------------------------------------
I am having a problem with a Siemens Hydroranger 200 with 4-20mA outputs. About every two weeks or so we will have one of the 4-20mA outputs go out and have to go to the second set of outputs. After the second set goes out, we have to replace the whole unit. We have surge suppression with proper grounding on 110 vac and 4-20mA lines. The only I know left is to replace the wiring. The output on the Hydroranger goes straight to an AB slc500 analog input module. Any thoughts??
