I would also do this lot as most of my hmi would be 24 v and Ethernet. I would also have buttons under the HMi So this would be another 24v cable and I never had a problem.
I didn't think it would be an issue.....just wanted to make sure.
I am doing a big Ethernet/IP system (16 addresses) with 24VDC control power (10 and 20 Amps DC control power).
So I was planning to run the DC power and Ethernet between cabinets in the same conduit.
