Do the instrument cables for DCS and ESD need to run in separate trays?
Thread Content
Do the instrument cables for DCS and ESD need to run in separate trays? I remember the specifications only stating that it should be run in separate cable trays from high-voltage circuits. DCS, ESD, and FGS should have separate wiring boxes. However, a colleague mentioned today that the instrument cables running from the instrument panels to the wiring boxes for DCS and ESD should also be placed in different cable trays. Is there any specification stating this? If so, please indicate what the standard is. Thank you
It is not specified; the standards state that switches and analog signals should be separated, as well as high-voltage and low-voltage systems.
They can be placed in the same cable tray, but it should be different junction boxes
It is necessary to strictly separate the cable trays for low-voltage and high-voltage systems. DCS, ESD, and FGS all belong to the low-voltage category; according to the design requirements, it is acceptable to use standard shielded cables and share a single cable tray and bus cabinet.
We can walk through the cable tray once. Generally, intrinsically safe and non-intrinsically safe cables, as well as signal cables and power cables, should be kept separate……

Sure, we all go together here
