I have found an installation where four 4-20 mA signals travel inside the same shielded wire. The shield is properly grounded at one end. I would recommend to separate each 4-20 mA signal in an independent shielded wire with its own shield, I had never seen such an installation and I cannot tell of the possible consequences of it.
The fact is that the signals are going to a videographic recorder, the user reports that he replaced the analog input card (6 channels) once as "warranty" with the manufacturer because all the channels were broken and now with a new analog input card he reports that one channel is broken again.
Could this wiring be the problem?
