As the title suggests, can it be placed in a cable tray? Should there still be some distance when placed together? Thank you
It should be fine; the voltage isn’t high.
The labels are in place, and the tag numbers are fine
It should be fine, as they all operate at low voltages; none exceed 36V
SH/T 3019-2016 \"Code for Design of Instrumentation and Pipeline Systems in Petrochemical Industries\" 7.1.9 Field buses and communication cables should be laid separately； When it cannot be laid separately, a partition should be used for separation. HG/T20512-2014 \"Code for Design of Instrument Piping and Wiring\", 8.1.14: The two wires of a redundant data communication cable shall be laid along two separate paths.
The requirements for the 6th floor are clearly specified. In current construction projects, they are usually placed in a cable tray; the standards require the use of shielded, specialized twisted-pair cables, but in practice ordinary cables are used as well – it depends on your requirements
