Ideally the 0-20ma should be in a screened lead where the screen is only terminated at one end (terminating both ends can cause reflections in the cable), Is saying that I do know of many installs I have seen where signals have been mixed in Silflex type cable with no apparent problems especially if these runs are not to long, current loops are certainly more resistant to noise and 24v signals should not interfere that much.
One no no is the 415 ac supply in a multicore with signal cables unless specially designed i.e. multiple types of cable combined often used in trolley systems with umbilical cords.
