Noise from high current in cable trays
There are NEC requirements, but also for noise and electromagnetic pick-up from adjacent power cables. This can be accomplished by a separate cable tray system or by a divider within a cable tray. In situations where there are a large number of cables varying in voltage and current levels, the IEEE 518-1982 standard has developed a useful set of tables indicating separation distances for the various classes of cables. In instrumentation EPC (Engineering, Procurement, and Construction) projects, installing cable trays is very important for making sure that signals are sent reliably, that people are safe, and that systems work well for a long time. However, these trays are not immune to safety hazards that could cause system failures, fires, or other catastrophic events. my question is that would it be possible to put instrument multicore DO cables in a tray with instrument multicore DI,AO and AI cables in a distance about 330 meters? any problem would be possible to happen such as due to Do signal ON and OFF excitation ( 24VDC on-off signal of valves) AO or AI or.
